“The description said leather, but frank leatherette arrived!”, “What is leather construction? Like leather or some kind of substitute?”- many of those who buy clothes and shoes where it is cheaper and of better quality - in foreign online stores - faced similar troubles and questions.

Leather (aka leather in English) is a multi-layered concept, and in every sense. Over the millennia, during which this material has been actively used in the manufacture of clothing, footwear, accessories, craftsmen have created a huge number of methods for dressing and processing leather.

From the same material, tanners can make a thing that is soft, and “oak”, and durable, and “just right”, and premium quality, and the budget segment. Therefore, leather in the product description should not mislead you - this is not at all a reason to believe that a store (even the most popular and reputable one) will certainly send you a high-quality leather jacket, bag, or, say, a pair of boots.

There are two big differences between “skin” and “skin”, as Odessans say. Let's talk about the difference.

And let's start with the very thing genuine leather.

Genuine Leather - leather from cattle skins

In terms of quality, genuine classic leather can seriously differ depending on the type of “manufacturer”.

Cow leather- one of the most popular types. As the name implies, it is made from processed cow hide. The result is a durable, strong, wear-resistant material, which at the same time has flexibility and a certain elasticity. Has a natural leather texture and thickness from 1.1 to 4 mm - on average, about 2-2.5 mm. It is mainly used for the manufacture of bags, outerwear, shoes of the middle price range.

Bull leather or Steerhide- despite its related origin to cow leather, this type of leather has quite significant differences from cow leather. First of all, in thickness - from 2.5 to 5 mm. Due to this parameter, bovine skin is very dense, tough, bends poorly, almost does not stretch and keeps its shape perfectly. It is used for the manufacture of high-strength (work) footwear, ultra-reliable outerwear, bags, belts, and other haberdashery goods - for example, key rings, bookmarks, etc.

Calfskin, calf, veal (“calfskin”)- thin, soft, plastic. Due to its elasticity and “tenderness”, it is often used in the manufacture of premium clothing, footwear and accessories (for example, gloves). At the same time, it has a predictably lower strength and durability compared to the types of leather listed above.

Buffalo leather- the densest, toughest and heaviest among the "cow" skins. Despite the relative thinness - on average, up to 3 mm, buffalo leather is resistant to mechanical damage and high moisture-repellent characteristics. It is found much less often of the types listed above, therefore it belongs to a higher price category. Coarse-grained buffalo leather is often used in premium accessories and is popular as a material for biker jackets, pants and shoes.

Cowhide, neat’s leather- strong, but at the same time plastic and elastic skin. Better than other leathers, it lends itself to all kinds of processing - dressing, dyeing, embossing, so the assortment of goods made of cowhide is very wide and varied. In addition to outerwear, shoes, accessories, cowhide is often used for upholstered furniture, decorating car interiors and living / working spaces, etc.

Goat leather, goat skin- one of the most delicate to the touch, thin, elastic types of leather. Has a characteristic “wavy” texture. Due to its plasticity, it is most often used in the manufacture of high-quality accessories (for example, tight-fitting women's gloves) and light outerwear that emphasizes the figure. Of particular note is the chevro skin, which is made from the skins of kids younger than 6 months: dense, with a pleasant texture in the form of fine wrinkles, it is most highly valued.

Shipskin ("sheepskin", "sheepskin")- has a characteristic “velvet” texture, lightness, firmness, softness and elasticity. It lends itself perfectly to any kind of processing, while maintaining a given shape. It is most often used as a basis for the manufacture of high quality outerwear, as well as accessories and hats.

Pigskin ("pigskin")- lightweight, elastic, thin, “porous”. This type of leather lends itself well to dressing and processing (for example, dyeing), however, it has certain problems with strength and water resistance. Therefore, pigskin is most often used in the manufacture of accessories - wallets, wallets, bags, and inexpensive clothing and shoes. This is the most economical type of genuine leather.

Horse leather, horsehide- differs in density, high strength and distinct "glossiness" in finished products. And this is not surprising, given that horse leather requires quite a long processing. From this type of leather, as a rule, they make high-quality outerwear for men, shoes, accessories (also predominantly “men's”), and are also often used in the production of all kinds of upholstery materials. Separately, it is worth taking out the skin of foals - thin, soft, elastic and expensive: it is used mainly in premium products.

Deerskin, deer leather, buck skin, doeskin- a very elastic material with high strength and excellent thermal characteristics. Deerskin is most often used to make suede material, which is used in the manufacture of gloves (deer, by the way, are considered the warmest), bags, briefcases, wallets. Also, after stiffening processing, it is often found as the basis for goods made in the Indian ethnic style.

Elk skin- similar in properties to deer, but more porous and silky to the touch. Differs in high strength, due to which it is often used in the manufacture of outerwear and footwear (for example, moccasins) for hunters.

There are a number of other exotic leathers:

crocodile - crocodile skin
snake - snake skin, snake leather; in particular, the most popular are python (pithon skin) and cobra (cobra skin)
ostrich - ostrich skin
kangaroo - kangaroo leather
shark - shark skin
stingray - stingray skin, stingray leather.

These skins are not often found on the European and American markets and are mainly used in designer collections of clothing, footwear, and accessories, which is due to their rather high cost. We will not dwell on each of the exotic types separately: as a rule, they do not save on dressing and processing of products, and therefore the output most often results in a high-quality, ergonomic and far from the most budgetary thing.

Having familiarized ourselves with the types of genuine leather, let's look at the options for its processing, on which the final cost and quality of products largely depend.

Types of leather processing

Natural hide in "pure" form is a rather unpresentable material. To make things from it look bright, beautiful, of high quality, give a pleasant tactile "response", the leather is processed - they remove the remnants of wool, apply one or another type of tanning, polish, apply various coatings (for example, to emphasize the texture or give a glossy shine), paint ...

The most popular leather processing methods that can be found in product descriptions in foreign online stores are as follows.

Smooth leather – smooth skin... It is made from high-quality hides and most often does not undergo almost any processing, except for the removal of wool: it is not polished and does not use additional coatings. Maximum - minimal ennobling treatment in the form of the lightest spraying of wax or paints. Thanks to this, the pores remain free, the skin “breathes”, providing physiological comfort to a person who will wear a product made of such material. In addition, it also increases the wear resistance and service life of the thing. Over time, a so-called "patina" appears on the surface of the skin - slightly darkened areas at the folds and in places of greatest friction, which gives the product a special chic. Smooth leather is usually used to make premium quality clothes, shoes, bags and accessories.

Krust - crust... It is a relative of smooth leather: crust retains an unprocessed front surface (maximum - natural wax), which, as in the case of smooth leather, allows crust products to “breathe” and also contributes to the appearance of a noble “patina”. Crust is often subjected to a special dyeing regime - through staining, in which the skin acquires color throughout the entire volume. Modern processing methods impart hydrophobic properties to this type of “skin”. Most often crust is used for the manufacture of shoes, accessories, riding goods (in particular, harnesses and saddles) and furniture constriction.

Aniline leather- aniline leather. This is the name of natural processed leather, on the surface of which a thin protective shell is applied. Aniline leather is considered the premium segment of the leather world - high quality, soft, natural and noble-looking, and the most prone to expensive-looking “patina”.

Semi-aniline leather- semi-aniline leather. The same as its aniline “brother”, but with additional coloring with various pigments and dyes. Due to this, it is more rigid and less "premium", but has increased resistance to external influences.

Corrected grain leather- skin with a corrected facial surface. In fact, this is an additionally processed semi-aniline leather: its surface was leveled as much as possible, then a polymer coating was applied and an embossing procedure was carried out to emphasize the natural texture of the material. The result is a product that is even tougher than semi-aniline leather, but it has reliable protection from moisture and dirt.

Nappa leather, nappa- in fact, thin (0.5-1 mm) corrected grain leather. Most often it is made from sheepskin, but skins of other cattle are also used. Nappa undergoes double tanning and a number of processing procedures that give it one or another decorative effect. It is used in the manufacture of hats, light outerwear, accessories and various decorative elements, including banners for car interiors.

Vegan leather- often this definition is interpreted as "vegan" or artificial leather... In fact, a vegan is a natural product. This is the name given to high-quality vegetable-tanned crust leather. Vegan is used in the manufacture of luxury apparel and footwear, biker apparel, equestrian and motorcycling products. It should be remembered that this leather belongs to the premium class, and therefore products made from it are unlikely to cost a penny. If a thing made of vegan leather is given away practically for nothing, it is most likely a “vegan leather” in its “frontal” understanding - artificial or eco-friendly.

Velur- velor. This is genuine leather that has undergone the procedure of tanning and subsequent polishing of the front or seamy side... Grinding "fluffs up" the skin, making its surface velvety. The result is a nice, but capricious material: it does not have a special strength and resistance to dirt, and requires careful maintenance to maintain its appearance.

Chamois leather- suede leather. Unlike velor, suede is sanded (“fluffed”) on both sides - front and back. Perfectly "breathes" (and just as well passes water, which may be a disadvantage), holds its shape well even when wet and after drying, and has the highest tactile characteristics, for which it is loved. Suede is most often used for the manufacture of clothing, including light outerwear, summer, demi-season and fashion shoes, hats, various accessories and jewelry.

Nubuk, nubuck- nubuck. Like velor, it undergoes grinding only on one side - the front side, acquiring a short, very fine pile. It is made of denser skins than velor and suede, due to which it has a higher strength, while maintaining "breathability". Most often, nubuck is used in the manufacture of shoes in the middle and budget segments, but it is also used in outerwear and upholstery materials. Like velor, this material is finicky and requires careful maintenance. Sometimes, in order to avoid problems with moisture permeability and quick pollution, nubuk is additionally impregnated with oil - this material is referred to as nubuk-oil.

Dogskin- like. Soft and elastic skin with a perfectly smooth facial surface. It is made from skins of young animals. Despite the tactile subtlety and tenderness, the husky has good durability. Most often it is used to make gloves, less often - light, tight-fitting shoes or accessories.

Сhevreau, kidskin- chevro. This is the name for soft and dense skin with an original wavy, wrinkled texture on the front surface. Previously, chevro was made from thin skins of young animals and this material was similar in properties to a husky. Nowadays, chevro is more and more often made from calf, sheep and lamb skins, which makes the material less “delicate” - inelastic, impermeable to water and air. Chevro is considered one of the best materials for making shoes; it is also used in furniture upholstery and in the production of accessories.

Sometimes you can find Chevrette leather with a pattern that resembles a chevro. However, the technology of its processing is somewhat different, which is why this type of leather has a noticeable "looseness" and reduced strength characteristics.

Saffiano leather, morocco leather, cross grain- morocco leather. This type of leather, due to a special dressing, as a result of which the surface acquires an unusual shimmering effect, seems to many similar to leatherette. Nevertheless, in front of you is completely natural leather (in most cases - sheepskin or calf), which has high strength, dirt and wear resistance. Model bags, wallets and other accessories are most often produced from this type.

Split leather- “split” leather, split leather. This material is obtained by mechanical “splitting” (roughing) of the hide into several layers - usually from 3 to 6. Thus, the split is front, middle and purl. Thin front Split leather is often used for lining for cameras 'and cameras' furs, as well as various accessories - gloves, hats, etc. The front split, in combination with the middle split, form the so-called split velor, which is used in the production of durable work shoes, clothing and upholstery materials.

Shagreen leather- pebbled leather. The root green, which you may have noticed in the name, is not accidental: earlier this leather was made from horse skins and was traditionally dyed in green color... Now it is made from sheep and goat skins and given any color. However, the word “shagreen” (shagrin), applied to the skin with a characteristic convex-granular texture, has been preserved. Most often, shagrin is used to create various decorative elements, as well as leather for technical purposes.

Cordovan- cordovan. A distinctive feature of this vegetable tanned leather is a smooth, glossy outer surface. This is practically an exclusive material: as a rule, it is made from horse skins, which are subjected to manual dressing for many months (up to six months). As a result, cordovan acquires premium properties: amazing strength, water resistance, dirt resistance, durability and characteristic gloss. This premium quality leather is used mainly for making expensive men's shoes.

Patent leather- patent leather. Well, everything is clear from the name: it can be any leather that has a varnish coating. Such processing gives the product additional attractiveness.

Pebble leather, pebble grain leather- grainy leather. Differs in texture - pronounced convex granular. Such texture in some cases (especially when it comes to exotic types of skins) is natural, but most often it is applied using special equipment. Its advantages: resistance to water and dirt, ease of care, interesting appearance.

And a little about the alternative

It is not uncommon for the word leather to appear in the description of a product, but it has little to do with the properties and quality of real leather.

For example, you can often come across the concept of leather construction - in this case we are talking about the so-called “recycled leather”, which is produced from tannery waste: various trimmings are crushed to obtain a fibrous powder, which is then glued together by adding latex or other adhesives. The resulting material is similar to natural leather and even has its smell, but its strength and quality characteristics are still lower than that of real leather.

And a separate item is faux leather and all kinds of leatherette. Modern production has reached such heights that the quality of such materials is often close to the quality of natural leather, but their cost is much lower - and this is a big plus for those who would like to purchase a high-quality, almost leather thing for little money.

Among the various types of artificial leather, the following are worth noting.

PU leather, polyurethane leather- PU or polyurethane leather. This material is made on the basis of natural, but damaged skins: the damaged face layer is replaced with the finest polyurethane fiber. The result is a product that, like natural leather, “breathes”, has a fairly high strength, and tolerates low temperatures well. The use of PU allows you to give the product almost any color that is often inaccessible for "natural", so products from this material can look much brighter and more attractive.

PVC leather, polyvinyl chloride leather, vinyl synthetic leather- PVC leather. The basis of this material is monolithic porous polyvinyl chloride (a chemical compound with good elasticity and pleasant tactile characteristics, similar to skin). PVC is applied to fabric, knitwear, various synthetics, and then impregnated with polymer substances that give the material strength and density. Vinyl leather is wear-resistant, has an attractive "leather" look, holds its shape well, and is easily cleaned from dirt. Outerwear is often sewn from it - youth or biker style, model and sports shoes, are used in the manufacture of accessories and in the hauling of car interiors.

Eco leather- eco-leather. It is also an absolutely synthetic material, except perhaps for the base, on which a layer of “breathable” polyurethane is applied - it can also be made of natural fabric. You shouldn't look down on eco-leather: experts assure that high-quality material has all the advantages of natural leather and, at the same time, is devoid of most of the disadvantages. Visually, eco-leather practically does not differ from natural, has comparable strength and durability, and also, unlike natural leather, does not require special care. And all this at a very humane price. Eco is used in a huge number of products - clothes, shoes, bags, belts, hats, decorative elements are sewn from it, as well as materials for upholstering furniture and car interiors.

Synthetic patent leather- patent artificial leather. It can be produced from all types of artificial leather by coating them with varnish. Has high strength, wear resistance, attractive appearance. Like eco-leather, it is used for the manufacture of almost everything - from clothes and shoes to decorative elements.

In general, artificial leather can be a very decent material. True, it should be borne in mind: their quality depends on the manufacturer's conscientiousness. If you trust the brand you intend to buy, then any type of faux leather in its description should not scare you - most likely, you will receive a quality item at a pleasant price.

The description clearly states that we are talking about Rubber Synthetic leather - rubberized artificial leather. However, given the status of the brand, there should be no doubt about the quality of this material.

Attention!

Often the phrase “Premium leather” appears in descriptions. At first glance, it reads unambiguously - “premium leather”. However, as practice shows, such a definition can hide both high-quality natural or artificial leather, and cheap leatherette. Again, it all depends on the integrity of the manufacturer and the scrupulousness of the online store in which the product is placed. Therefore, deciding to purchase shoes or clothes from Premium leather in some online stock at an attractive price, do not be lazy to look for the same model on the official website or in trusted stores that give a more complete description.

One of the most frequent questions that readers ask me is: "How do I know if shoes or a bag are made of pigskin?" For a Muslim, it is very important what material a thing is made of.

So pigskin. In the fashion industry, many brands use pigskin / suede to make accessories such as shoes, belts and bags because it is cheap, which drives down the price of the item. I don’t know what it’s connected with: either because it’s easier to tan pork skin, or because it’s easier to get pigskin (because pigs are very fertile).

I hope that Muslims will benefit from this publication and will be able to figure out what kind of leather products they buy. In real life, I can identify pigskin by its specific features and texture. When it comes to buying from an online store, then again there is an easy way to determine if it is pigskin or not.

1. Physical properties.

Most main feature pigskin is the presence of a three-point pattern over the entire surface of the skin... Take a closer look, there are many variations of the three dot symbols, but they all have one thing in common: the three dots are so close to each other that they form a kind of group. I call it Mickey Mouse symbol because ... well, doesn't it look like it?

Another sign is that pores are visible on the entire surface... On a typical pigskin, you can easily notice the pores. Some manufacturers try their best to mask this so that the pores are no longer visible, but Allah is Merciful: what is wrong cannot be completely hidden.

So how do you recognize pigskin even from a photograph? Very simple. You will immediately notice where she is.

For example, this insole is like pigskin.

This is obvious because there are three points.

This is another variation of the pigskin insole. When you enlarge the photo, you again notice the three-point pattern, the pores are clearly visible.

Pigskin footbed in neutral tones.

Do you see the pores? Yeah. So it's pigskin!

I call this "pig suede". Even in suede, the pores are clearly visible and a three-point pattern can often be seen.

And this I call "smoothed" pigskin. I think it's the skin of an old pig.

Do you think this is pigskin? Yes!

Here's another version of the "smoothed" pigskin. The pores are strongly smoothed, but visible.

These shoes from the Sandro label can fool you: it's easy to think it's calfskin. But - wait a minute - can't you see the three-point pattern?

And here - as if peeled pigskin. The Asos label itself is made of sheep.

If you see that the label says that the skin is not pigskin, be sure to look at the sides of the shoes, because sometimes individual brands, in order to reduce the cost of products, trim the sides of the shoes with pigskin. Here are some examples:

How do you know it's NOT PIG SKIN? Remember what the skin of other animals looks like.

Typical young calf skin is smoother and smoother than that of an adult bull. The grain on the skin is almost imperceptible, it is very smooth.

Small pores are visible on sheep's skin, but they are not grouped in three, as is the case with pigskin. Take a look at the Asos label I pointed out to above.

Buffalo skin is similar to the skin of an adult bull, but more "grainy" and rather heavy for bags. And, like calf skin, the pores are not visible, unlike pigskin and sheep skin.

Deer skin is a bit like the skin of a young calf, as pores are not visible on it (as I understand it) and it is not "grainy", unlike buffalo. To the touch, it differs from all others.

Ostrich skin is easy to recognize. The pores on it are very noticeable, they are embossed and clearly visible. In this it looks like a pig's skin, but the pattern of ostrich skin is one-point, there are no groups of three points.

Examples of calfskin insoles:

This is not pigskin because it is not pores, but perforations.

Sometimes it happens that you have doubts. And then it is very likely that the skin is pork. For example, as with these McQ shoes:

Doubt immediately creeps in: it is either smoothed pigskin or calf. But, looking closely, you can find confirmation that the skin is pork.

2. Smell.

It is very difficult to describe the smell in the text - you have to smell it yourself. I can say that pigskin has a pungent smell, vaguely similar to the smell of burnt leather, in contrast to the intoxicating aroma of calfskin.

I once bought boots over the internet. Looking at the photo of the insole, I was sure that it was not pigskin. There was no photo of the sidewalls on the Internet, and I bought it blindly. When the package arrived and I opened it, I smelled a familiar smell. Pigskin smell? But where could the pigskin be? And she is on the sides!

3. Price.

Another easy way to determine if a product is made from pigskin (especially if you buy from overseas online stores) is to look at the price. Most of the cheap shoes will have pigskin insoles because this reduces the cost.

As for brands, I avoid many of them, because their shoes have pigskin insoles. I say this with confidence, because I saw these shoes in real life - in stores in London.

These are the following brands:

Kurt Geiger (especially cheap models, with rare exceptions).
Hudson.
Swear.
Most of the "mid-range stores" eg Topman, River Island, New Look.
In H&M, somewhere they use pigskin insoles, and somewhere they use synthetic ones.
Most of Asos shoes.
Most of the shoes are nubuck from Nike.

As for brands such as Gucci, Prada, Fendi, in general I confirm that they use calfskin. That is why they are so expensive.

The most important - CHECK BEFORE BUYING... You need to make sure the skin is not pork skin. Maybe even at Gucci or Fendi you will find pigskin ... (by the way, under the Gucci label, women’s handbags made of pigskin were produced, which was openly reported).

If in doubt, don't buy. As a Muslim, I never buy pigskin products. Point.

Leather: types of leather, methods of leather dressing.

Leather is a strong and durable material that is made from the skins of various animals. Leather production is one of the most ancient. Man has long learned to process leather and use it to make clothes, shoes, bags, accessories and various household utensils. Genuine leather is classified according to several criteria: by purpose, by the type of raw materials used, by the method of dressing and finishing.

Leather dressing methods

Crafted leather is usually divided into three main types: raw leather, rawhide and tanned leather.

Raw leather (raw, cast)- leather material of the most ancient way of production. Usually, she only cleans the skin and removes the wool, that is, this is what is called "leather" in the leather industry.

Rawhide (damp, ball)- leather material of the ancient method of dressing. It is produced by loosening the structure of the skin with the fixation of this state with fatty substances. It was ubiquitous, but now it is practically superseded by tanned leather.

Tanned leather (sheepskin coat)- pelt (raw leather) treated with tanning agents to impart plasticity, strength, durability, etc. In the old days, oak bark was used in the process of making leather, hence the name "tanning".

Despite the difference in methods and recipes for processing leather, there are general mandatory steps. The first generic operation is flesh, in which the skin is deprived of the remnants of meat, fat and subcutaneous adipose tissue. Then, if required, dehairing or cindering is performed, removing hair and epidermis. The resulting product is called cast.

Mereya- This is a pattern on the surface of the skin, formed by traces of hair follicles removed together with the epidermis as a result of tanning the skin.

Bakhtarma- the inner surface of the skin formed after fleshing.

Types of leather tanning

After the initial processing of the leather, tanning is started. According to modern concepts, tanning is the process of bonding collagen molecules with tanning particles (cross-linking of molecules). There are many types of tanning now:

Vegetable tanning- in the manufacturing process, oak bark and other ingredients obtained from plants are used. The result is an elastic material Brown color... The desired shade is achieved by varying the quantity and quality of the ingredients used and by choosing the color of the raw material. Vegetable tanned leather is not water resistant. When exposed to moisture, it changes color, and if it absorbs liquid and then dries, it will decrease in size (shrink) and harden, become less elastic. In hot water, this type of leather shrinks and becomes a hard, brittle material, which affects its quality and limits its use.

Iron tanning- it is used very rarely due to the negative properties of ferric iron to catalyze the destruction of collagen.

Aluminum tanning- For tanning, usually aluminum alum is used, which, upon hydrolysis, form tanning basic aluminum salts. Compared to chromium salts, tanning basic aluminum salts have a weak tanning effect. Aluminum tanning is used mainly for the manufacture of glove leathers (huskies). To increase heat resistance, it is possible to use aluminum and organic tanning agents at the same time.

Chrome tanning- Trivalent chromium salts are used for tanning. The softness and elasticity of chrome-tanned leather is higher than that of tannid-tanned leather. More resistant to high temperatures. In humid conditions they get wet faster and dry more slowly. Chrome tanning agent stains bakhtarma in a gray-green color.

Zirconium tanning- Zirconium tanned leathers have good strength and abrasion resistance. Zirconium tanning agent paints bakhtarma white.

Titanium tanning- the leather obtained by titanium tanning has basically a quality similar to that of zirconium tanned leather and does not stain the bakhtarma.

Fat tanning- In fat tanning, pelt is treated with fats containing unsaturated fatty acids. These include the fats of marine animals (seals, sperm whales and fish). The mechanism of fat tanning is complex and is currently interpreted in different ways. It is usually believed that in the tanning process, the oxidation of unsaturated fats occurs due to the addition of air oxygen double bonds at the site. Oxidation products enter into a chemical bond mainly with the amino groups of collagen. Fat tanning is used to produce one type of leather - suede. Fat-tanning gives the leather high water resistance and softness. When in contact with water, suede leather initially lets it through, but becomes waterproof as it swells. This property also allows the use of suede as special filters.

Tanid tanning- Vegetable tannins and synthetic tannins (syntans) are used in tannin tanning. They are compounds of the carbocyclic series, being derivatives of polyhydric phenols. Plant extracts containing tannins (for example, willow, spruce, oak, quebracho) are used as raw materials for the production of plant tannins. Phenols, resorcinol, naphthalene resotan, etc. are used as raw materials for syntans production. Tanides bind to amino groups of collagen molecules. In addition, they are deposited as a filler in the skin. Tanides give the skin a number of valuable properties: increased thickness, plasticity. They are mainly used in the manufacture of plantar leather. Currently, due to low heat resistance and wear resistance, pure tannin tanning is not used. Tanid tanning is usually combined with chrome, titanium and zirconium. This allows you to obtain leather with the advantages of these tanning.

Aldehyde tanning- Of the aldehydes for tanning, formaldehyde and glutaraldehyde are used. They are currently not widespread. Formaldehyde tanned leather is thin. Tanning with glutaraldehyde is of great interest. In terms of physical and mechanical properties, glutaric leather is close to chrome, but it is distinguished by high perspiration resistance, alkali resistance, softness and elasticity. Such tanning, due to imparting high perspiration resistance and microbiological resistance to the leather, is advisable to use for the production of insole leather.

Combined tanning- Combinations of tanning agents are used to give the leather the beneficial quality of each tanning process. For example, the use of chrome compounds for tanning gives leathers high wear resistance, heat resistance; tannides - plasticity and increased thickness; zirconium compounds - density, strength, etc. Of the combined tanning, the most widespread for the production of sole leathers are: ХР (chromium-vegetable), ХТС (chromium-titanium-syntanic).

With poor penetration of tanning agents into the structure of the dermis (in the case of thick and dense leather tissue), such a defect in the skin as bad tanning occurs (in the form of a light strip in the center of the cross section of the skin).

Types of leather by type of raw material used

Skin of cattle (cattle)

Calfskin- is considered the highest quality and most valuable leather. It is used to make shoes, clothes, belts, accessories, upholstery and is an affordable and popular material for making bags. Calfskin is smooth, soft, durable, does not break or crack on its surface. Production includes chrome and vegetable tanning. Calfskin bags are very elegant and do not wear out for a long time.

Calf skin, depending on the age of the animal, is subdivided into the following types:

1. Slime- the skin of unborn calves. Skin thickness from 1.0 to 1.4 mm. Used to make haberdashery leather.

2. Calms- the skin of calves up to 6 months old breastfeeding... Soft, delicate, elastic, it is considered the most valuable skin. Skin thickness from 0.5 to 1.4 mm.

3. Outgrowth- skin of calves up to one year old, feeding on plant food. The skin is less elastic and softer than the calves. Skin thickness from 0.7 to 1.6 mm.

4. Half-leather- skin of calves under the age of 1.5 years. The leather is tougher and is cut. Skin thickness from 1.0 to 3.0 mm.

5. Yalovka- the skin of a calved cow is denser and more uniform in thickness; superior in quality to the bull and bull. The skin of a calving cow is distinguished by a small saddlecloth and large thin floors. Cow skin is available in thickness from 1.2 to 4.0 mm. The leather is cut.

6. Goby- the skin of a young bull (up to 5.00 mm thick). It is used for the production of shoe and technical leather.

7. Bychina- the skin of castrated bulls. Has a thin hairline. It is used for the production of footwear, saddlery and technical leathers, raw materials.

8. Buffalo- the skin of bulls. It is the thickest and heaviest among cattle skins, has a rough and loose structure. The heaviest and thickest is buffalo skin. Due to their thickness and strength, such leathers have a long service life, but they are rarely used in production. Compared with bovine, it has thickened floors, knobs, rump; more wrinkled skin. It is used for the production of technical leathers and raw materials.

Sheep and goat skins

Sheep skin have a large thickness of the papillary layer of the dermis - from 50% in fine-wooled to 80% in coarse-haired. Low strength and good plasticity are inherent in such skins. Due to the weak connection between the reticular and papillary dermis, lagging of these layers can be observed. Used to make chevrette and haberdashery leathers.

Goat skin- durable, soft and thin material with a beautiful measure. Goat skins have a large thickness of the reticular layer (up to 60%), dense interlacing of collagen bundles, which makes these skins dense and durable with a small thickness. Used to make chevro.

1. Chevro(from French "сhevreau" - kid) - leather made from the skins of kids up to 6 months. It is considered one of the most expensive lame tanned leathers. Very beautiful, dense, elastic chevro skin has a strong structure with an original pattern on the front side in the form of fine wrinkles. It is used for the tops of footwear (including children's), haberdashery, clothing, furniture upholstery.

2. Kozlina- goat skin made from an adult.

3. Chevret- leather, lame tanned from sheep skins. In terms of design, the mei is similar to a chevro. Used for the top of shoes, clothing and haberdashery.

Pig skin

Pigskin- the most economical and unpresentable type of leather, it differs in appearance and structure from cattle leather. Pigskin is nowadays mainly used as a lining material and rarely as a main material. This is due to the fact that pork skin is not elastic enough, gets wet quickly, has a rough and hard surface, and also has a persistent odor. In addition, it is not strong enough, and the ugly perforated texture in the product does not look interesting.

Horse skin

Horse skins are not often used in leather goods production. Due to the numerous highly developed sweat and sebaceous glands, the dermis is looser than that of cattle skins. The front is more suitable for making soft leather; Khaz is used to make tough leather.

1. Slime- skins of unborn or stillborn foals. Hair is almost absent, mane is not developed; in properties it is close to opoyka. Used to make haberdashery leather.

2. Foal- the skin of dairy foals is a valuable material. The skin is uniform in thickness and has almost no defects, which is why it is highly valued. It is used for the production of haberdashery leather and shoe uppers.

3. Lesson- the skin of foals that ate plant foods.

4. Fringe- skins of young horses up to one year old. It is used for the production of leather upper shoes.

5. Large horse raw materials- area up to 400 sq. dm., thickness 1.5-3 mm.

Deer skin

Deer skin- very elastic leather, has high strength and heat protection. Most often, suede material is made from deer skin. Used for the production of gloves, briefcases, bags, wallets. The warmest gloves are made of deer skin.

Moose leather- elegant, durable, silky to the touch leather, similar in properties to deer, but has a slightly more porous structure. Used for sewing men's outerwear and accessories.

Camel skin

Camel skins produce low-quality, low-strength leather, which is used mainly for leather goods.

Cut raw materials from finished leather

In the production of leather, they are cut and have various configurations. This is determined by the size of the hide and the range of finished leathers.

- Whole skin.
- Semi-leather- half of the skin, cut along the back line.
- Kulat- a skin with a cut off collar.
- Vorotok- part of the skin from the neck, usually has many blemishes.
- Cheprak- the most valuable part of the hide is the dorsal part, which does not have a floor and collar. It can be up to 55% by area of the area of the entire skin. It can be divided into “upper saddle” and “lower saddle”. It is usually used for the production of belts, bags and other products that require high density of raw materials.
- Krupon- saddle cloth, cut in the form of a rectangle.

Areas of the hide with the most defects:

- Paws.
- Paul- part of the skin from the peritoneum.
- Flanks- areas of the skin adjacent to the paws from the ventral side.

Horse hide is subdivided into the following sections:

- Haz- the back of the hide (croup and legs).
- Der Spiegel- thickened areas of the skin, located above the articulation of the pelvis and femurs. Khaza site.
- Front- skin without khaz. Most valuable part.

Classification of finished leather by purpose

- Saddle leather- for human and equestrian equipment. Used the skin of cattle and pigs.
- Technical leather- for mechanisms (eg drive belts).

A broader classification includes the following items:

- Leather for the upper of shoes- for these purposes, chrome-tanned cattle leather, horse fronts and whips, chevro with various finishes - nubuck, velor, split leather, varnish are used. For the top of heavy shoes, leather is used.
- Lining leather- designed for shoe lining parts. Pork skins are mainly used for these purposes.
-Leathers for the bottom of the shoes- used for the manufacture of insoles and shoe soles. For these purposes, pork skins and cattle skins, as well as horse khaz are used.

Skin types

There are many classifications of leather, which differ in the type and age of the animals from which they are obtained, as well as in the way they are processed and dyed.

Here are some examples:

Bovine skin- its thickness, in contrast to calf skin, is 2.5-5 mm, and the size of the skins can exceed 2.5 sq. M. Traditionally, it is called "saddlery". It was originally used for the production of saddles, harnesses and other harness elements. Nowadays, bovine is used, as a rule, for the manufacture of denim belts, ethnic style bags, wardrobe trunks and backpacks. This type of leather is better than others for hand and mechanical embossing. Due to the thickness and strength of the leather, products made from it can last almost forever.

Bovine skin

Buffalo skin- according to its main characteristics, it is very close to bovine skin, but the skins still have large size and an interesting "coarse-grained" (or "harvested") texture of the front surface. Resistant to moisture and mechanical damage. Very popular in biker jackets and accessories. Unfortunately, this type of skin is not widespread in Russia.

Cowhide- plastic, elastic, durable leather with an impressive natural texture of the front side. Accepts well various types of dressing, processing and coloring. It allows you to get a significant range of leather materials of various colors and textures, including elite and exclusive. It has a wide range of applications, including: sewing clothes, footwear and haberdashery, upholstering furniture, upholstery and decoration of car interiors, residential and office premises, the manufacture of decorative and gift items.

Cowhide

Cow's skin- strong leather, less thick and less tough than bovine. Has a pleasant natural texture, wear-resistant. It is used for the manufacture of haberdashery goods, outerwear, footwear and accessories of a moderate price range.

Calfskin- thin, soft, plastic, silky to the touch skin, has a natural "breathing" structure, high strength and wear resistance. The characteristics, use and cost of calfskin depend on the age of the animals. The skin of calves of milk age (up to 6 months) - calves - perfectly drapes and holds its shape, has high elasticity and resistance to deformation. High quality clothing and accessories are made from it. The skin of calves up to one year of age - the outgrowth - is thicker, less elastic and serves for the manufacture of high quality shoes, bags and other haberdashery products and accessories. The toughest and densest skin of calves up to 18 months of age is half-leather. It is used both for the manufacture of high-quality shoes, bags, suitcases and various souvenirs, as well as for interior decoration.

Calfskin

Opoyek- Soft, elastic leather obtained from the skins of suckling calves. Most valuable leather. Fibers are thin, elastic, dense weave. The calf's hair is thicker, thinner and more beautiful than that of an adult animal. The calf skin turns out to be soft, full, with a beautiful measure.

Opoyek

Outgrowth- the skin of a calf that has switched to plant food, changing the primary hairline during the molting process. The quality of the leather is worse than that of the calfskin, the interweaving of the fibers is weaker. The finished skin is even, thick, with a beautiful grain, but not as full as the calves. Upper shoes and leather goods are made from it.

Outgrowth

Pigskin- rather thin and light skin with a characteristic large-pored texture. Accepts dressing and coloring well, but does not differ in strength and water resistance. It is used for the mass production of inexpensive haberdashery goods, clothing, shoes, accessories, upholstery and lining materials.

Such leathers undergo chrome or chrome-free tanning and undergo cover or through dyeing. To protect against moisture, the front surface of the crust is treated with natural wax, while maintaining the natural breathability of the skin. Crust is used for the manufacture of footwear, haberdashery and office products, upholstery of furniture, the manufacture of riding goods (saddles, harnesses) and special-purpose goods (scabbards, game bags, holsters, etc.). Trust products are durable, with prolonged use in places of folds and constant friction acquire more dark color(patina) and the effect of natural aging.

Krust

Vegan(Vegan) - crust, tanned with substances of natural (vegetable) origin. To obtain a vegan, both cattle skins and pork skins are used, with a thickness of 1 to 3 mm. Designed specifically for the manufacture of carved elements, carving and embossing, which are widespread in subcultures, the biker environment, as well as in the manufacture of traditional elements of the costume and everyday life of the inhabitants of the western United States (belts, game bags, holsters, scabbards, etc.).

This material can be equally soft and thin, also hard and thick, it all depends on the processing technology. It is used for the manufacture of tops of shoes, clothing and leather goods.

Velours

Natural velor gloves.

Suede leather- oil-tanned leather (ie raw hides, subjected to preliminary preparation. When tanned, impregnated with fats). Serves for the manufacture of shoes, gloves, haberdashery, outerwear, jackets, skirts, and also as a filtering and polishing material. High-quality shoe suede is obtained from the skins of deer calf, outgrowth and Russian short-tailed sheep, technical - from the sheepskin of Russian long-tailed sheep, wiping - from the skins of adult deer, Russian sheepskin. Suede has a high ductility and porosity, which makes it more breathable. Suede is distinguished by its special softness, which it retains not only after soaking in water, but also after washing in soapy water, which is why Suede is also called “washable leather”. This material is less durable than smooth leather and requires careful maintenance.

Suede leather

Laika- Thin, soft, elastic skin. In the old days, it was made from dogs - hence the name, now it is mainly made from the skins of lambs and goats with chrome or chromium-fat tanning. The surface of the grain should be perfectly smooth, without wrinkles. Despite the softness and tenderness of the husky, it is quite durable and wear-resistant. It is mainly used for the manufacture of gloves, decorative items and ornaments, much less often - in the manufacture of light footwear and haberdashery. Laika does not tolerate moisture well, and after drying it loses its shape and properties. Products made from huskies require proper care.

Nubuck is similar to suede, but it is made from other types of leather, usually cattle. Nubuck is less resistant to dirt and pickling faster than suede. Nubuck requires careful attention, especially in the first month of wearing. Nubuck like a sponge absorbs any moisture and it will be good if you are especially careful during this period. It goes away later. Remember that light-colored nubuck clothes darken over time, and dark ones lighten. Nubuck is durable and durable with proper care.

Nubuck

Distinguish: natural nubuck, artificial nubuck, nubuck-oil.

Natural nubuck made of genuine leather. Has a weak bristle on the front surface, which gives the skin a good appearance - it becomes velvety. Genuine leather nubuck has good breathability. The disadvantages of this leather include low wear resistance and the need to care for products. Products made from natural nubuck must be cleaned with special products.

Natural nubuck

Artificial nubuck or synthetic is much cheaper than nubuck made of genuine leather. It is a multi-layer polymer material that has a velvety texture and is similar in appearance to natural nubuck. Unlike natural nubuck, synthetic nubuck does not absorb water and is more durable.

Artificial well-well

Nubuck oil- this is nubuck, which during the production process was protected from moisture by processing with a fat impregnation. Nubuck is soft and velvety to the touch, while nubuck oil is moist to the touch and heavier than regular nubuck. It is more durable and unpretentious than regular nubuck.

Nubuck oil

Crazy(Crazy) - refined leather with an elegant matte face and pull-up effect. Unlike nubuck, after sanding it undergoes a special stretching and waxing treatment. This treatment gives the effect of lightening and "floating" color in places of skin stretch. Also used for making shoes and as furniture material.

Chromic and chromium-fatty skins of cattle and pigs are subjected to exfoliation. The front, middle and back (bakhtarmyany) split is obtained by lamination. Thin facial splits are used to obtain high-quality haberdashery and photo leather. Thick front and middle split cuts form a velor split used for the manufacture of technical footwear, workwear and for the manufacture of upholstery leather.

Split

Split-velor

Cheprak(butt) - heavy, dense, thick leather produced by fat tanning from cattle hides taken from the back of an animal. This type of product usually goes to leather for belts for both men and women, since this is the densest part of the hide.

Chevrette(Chevrette) - elastic, viscous, dense and loose leather obtained from chrome tanned young sheepskin. The pattern of the front surface resembles a chevro, but is much less durable and worse in quality. It is used for the manufacture of outerwear, footwear and haberdashery. To increase the strength, the loose chevret is treated with polymeric and other materials. A more durable variety of chevrette, better suited for sewing shoes, is obtained from the skins of sheep of coarse-wooled steppe breeds.

Chevrette

Cordovan(Cordovan) - durable, strong, elastic exclusive vegetable tanned leather with a shiny smooth front surface. It is made from individual sections of horse hide by very long-term manual dressing (about 6 months). Cordovan is waterproof, durable, easy to clean from dirt, retains its shine for a long time. Used for sewing exclusive men's shoes.

Yuft- Thick leather produced by fat tanning from cattle hides taken from the belly of an animal. Much softer and more flexible than saddlecloth or blinker. It is made from barn or cow raw materials and skins of one-year-old bulls, with the exception of veal raw materials. After washing and fleshing, the raw material is subjected to ash, washing, trampling and kneading in crushes and drums, cutting, shavings, wringing out the face, boiling in jelly, filling in weak tanning juice and then juice and bulk tanning. Yuft is white, red and black. The best skins are selected for white leather.

Yuft

Cowhide leather- "Yalovy" in the Slavic languages denoted animals that had not yet given offspring. Cowhide leather for boots was made from the skins of one-year-old gobies or cows that had not yet given birth. Such leather was optimal for durable and comfortable shoes... Older or younger animals were not suitable - the delicate skin of the calves was still not strong enough, and the thick skins of old cows and bulls, on the contrary, were too hard and heavy to wear.

Cowhide boots

Chromium- Chromium foals are chrome skins made from foal skins. This subspecies of leather is produced in very small quantities, since the bulk of the raw material is used for the manufacture of fur. The thickness of the leather ranges from 0.4 to 1.0 mm. This raw material is mainly used for the manufacture of officer's chrome boots.

Chrome boots

Kirza- shorthand for the Kirovsky plant, where they began mass production of these products during the Great Patriotic War, - dense durable multilayer fabric. The term is more often used in relation to shoe tarpaulin - a composite material consisting of a multilayer fabric treated with film-forming substances (actual tarpaulin). Used as a skin substitute. The surface of the shoe tarpaulin is embossed to imitate the texture of pigskin. It is mainly used in the production of tops of army boots, as well as for the manufacture of rubberized drive belts, pouches, tablets.

Kirz boots

Aniline leather(aniline leather) - leather dyed with organic dyes with minimal processing. It is the highest quality of all leathers. It is characterized by marks caused by nature, for example, scars and different color shades. It is this type of skin that is more sensitive and prone to patinating (acquiring an antique look) during use.

Aniline leather

Smooth skin- made from the highest quality raw materials, not polished. Only the wool is removed. The pores of the skin remain in their natural state: the skin "breathes" and, at the same time, the service life of the product increases. Products made from this type of leather are more wear-resistant. In the process of wearing, a natural “patina” appears on the surface of the product and it becomes more beautiful every year. The highest quality furniture and shoes are made from smooth leather.

Smooth skin

Brushed leather- the skin is subjected to grinding and breaking. Sands on one side where natural pores are present. The other side is smooth. It is used for the manufacture of footwear, haberdashery products, clothing.

The resulting embossing pattern can imitate the skin of reptiles (snakes, crocodiles), exotic animals.

Embossed leather

Parchment- leather, which got its name from the name of the Greek city of Pergamum. This is raw leather made from the skins of lambs, kids, calves. Used to make musical instruments such as drums, some machine parts, book bindings, and women's jewelry. In the old days it served as the main material for writing.

Fish skin- Manufacturing of fish skin began in ancient times, before it was one of the main materials for sewing clothes and shoes. Fish skin is a material with excellent consumer properties, a beautiful and varied texture. The leather is produced from fish processing waste and has excellent development prospects. Each skin is good in its own way. Salmon - honeycomb, carp - shaggy, sturgeon - with thorns and stars. Now fish skin has begun to be used in industrial production, from it they make: clothes, shoes, various accessories and decor items.

Fish skin

Fish skin shoes

Patent leather- this is chrome-tanned leather with lacquer coating or duplicated with a lacquer film, which gives the surface a mirror shine. The quality of patent leather largely depends on the properties of the varnish coating, which must have a certain thickness, the necessary ductility and resistance to repeated bending. Good-quality patent leather should have a shiny, non-sagging film, a uniform color. An amazing glossy, shiny finish gives natural patent leather an exquisite originality, but unfortunately, it has poor durability and low temperature resistance. At temperatures below -10 ° C and above + 25 ° C, patent leather becomes cracked. It is not recommended to wear patent leather shoes in bad weather. From dampness and street dirt, the shiny varnish surface gradually fades and becomes covered with small cracks. Patent leather shoes require special careful care. Periodically, shoes are lubricated with glycerin, petroleum jelly or castor oil to protect them from premature cracking in heat or frost; varnished shoes should be stored wrapped in paper.

One of the most frequent questions that readers ask me is: "How do I know if shoes or a bag are made of pigskin?" For a Muslim, it is very important what material a thing is made of.

1. Physical properties.

The most important sign of pigskin is the presence of a three-point pattern over the entire surface of the skin... Take a closer look, there are many variations of the three dot symbols, but they all have one thing in common: the three dots are so close to each other that they form a kind of group. I call it Mickey Mouse symbol because ... well, doesn't it look like it?
