What is imitation leather?

When artificial leather was invented, hardly can be determined. However, about 100 years ago, cases and surfaces of instrument handles and cameras were covered with coated textiles, which had the look of a smooth leather surface. And not all of these surfaces were made of imitation leather only to save money. Also valuable items were processed with the still new material.

Iimitation leather is a material that looks like leather, but can not be declared as such, because it is not leather in the sense of the standards.

Since leather is an expensive material and because of the grain structure and natural markings and the irregular outer contour of a leather skin, the leather cutting waste costs are very high. Attempts have always been made to present a leather surface by means of a substitute material. Synthetic leather is used in almost all areas where leather is used: Shoes, clothing, furniture or vehicle upholstery.

Visually, the manufacturers succeeded very well in imitating a leather surface. The technical properties of leather (breathability, haptics, water vapor permeability, etc.) are not reached by artificial leather. Therefore, imitation leather remains to be the inexpensive alternative to genuine leather.

But there are also areas where artificial leather is better than leather. A motorcycle seat, the outer cushions on boats or the seats of jet ski are more durable than the alternatives in leather. Sun and water would be too strong for the leather.

Iimitation leather as boat upholstery material is more weather-resistant.

Also in the medical field (dentist chairs, massage beds, examination and treatment furniture) upholstery is more durable, if processed with artificial leather. Such furniture must be regularly disinfected. Disinfectants are mostly solvent based. This would cause the finish of leather to dissolve and to get brittle.

Imitation leather is also used where surfaces need to be replaced frequently or is cleaned with stronger cleaning agents.

Imitation leather expressions

There are many expressions for immitation leather. faux leather', fake leather, leatherette, synthetic leather, artificial leather or skai are just some of them. Artificial fur is called Artificial fur or Fourrure artificielle. Modern synthetic leather have a polyurethane coating instead of the PVC coating. Therefore the name PU imitation leather is also used. Some Chinese call imitation leather PU leather and the Portuguese call it napa and there are a lot of other expressions in other countries.

There is also an intention to surch for names which hide that the material ist not genuine leather. Names like Coskin, like leather, textile leather, pleather, vegan leather, vegetarian leather or Pellissimo and many more expressions are used to make sound the material more valuable.

The distinction between leather and artificial leather

The distinction to genuine leather is not always easy, even for experts. There are good forgeries, which can not be distinguished at first glance. In this case, it is generally necessary to check the material in the laboratory. The following are some of the distinguishing features, but a characteristic alone is often not enough. Only experienced experts with daily use of these materials are able to quickly determine what kind of material is present in most cases.

All synthetic leather objects. The distinction to genuine leather is not possible by just looking at it.

The reverse of the material

Characteristic of artificial leather is usually a textile backing, which is coated with smooth, grained plastic coating. Leather is fibrous on the back. But there are also artificial leathers, where even the back looks like a real leather and also experts at first glance can not identify the material as artificial leather. For the end user, it is therefore even more difficult to distinguish leather and artificial leather. At door panel or at handbag mostly ther is no access to the back of the material without disassembling or damaging it. In case of velor fabrics (like Alcantara), it is not easy to recognize the difference to nubuck and suede.

The grain structure

The grain pattern is more irregular in real leather because artificial leather has to be embossed, resulting in a more uniform surface. This is also the case with embossed leathers. Therefore, this assessment is only conditionally conclusive.

The cutting edge

WWhen a synthetic leather is cut, the cutting edge is often smooth and clean. In leather, this is rather linting. Leather is a fiber structure under the magnifying glass. The grain side has a dense fibre layer and becomes more fibrous towards the center and back. In the case of artificial leather, the top layer is very dense and without fibers and then usually a fabric. Even if there are fibers on the backside, the cutting edge can be frayed and then fabric threads get visible. Sometimes the artificial leather is only a pure foam foil.

The cut edge of artificial leather looks different than with genuine leather.

Behavior when heated

Imitation leather melts at high heat and burns well while leather only glows and solidifies without burning with flame. For artificial leather the burn smell is like burnt plastic. In leather like burnt hair. This test is not enough in case of mixed materials.

Leatherette is much more flammable then genuine leather.

Haptic and stretchability

Experts also note that synthetic leather is often thinner and stretches more when heated. An end user can hardly recognize this due to lack of experience. If the materials are glued on hard surfaces (e.g. steering wheels, table tops), this feature can not be tested.

Sometimes is argued that artificial leather would feel colder than leather. But there are exceptions. Good imitations with smooth or rough surfaces can feel warmer than bad comparative leather. The natural haptic of a thick aniline leather can not be copied until now. But also experienced leather experts have to check this because the end user does not recognize the difference because of the lack of experience.

The smell

It is often argued that leather can be recognized by the smell. Only very natural leather has a characteristic leather smell that is not transferable to artificial leather. There is not one "leather smell", but very different leather odors. Some artificial leather manufacturers perfume the material so that it smells like leather. The smell test is therefore only an indication among other indices and rather a test for experienced leather experts.

The breathability

A distinctive feature is the breathability. Even strong coated leather has more breathability than unporforated artificial leather. In rubber boots you sweat more quickly than in a waterproofed trekking boots made of leather. When you sit on synthetic leather surfaces for longer, you notice that you sweat faster than on real leather. But artificial leather can be micro-perforated to make it more vapor-permeable. This test would not lead to a correct result in such cases. This test also is unsuitable for suede and nubuck and their imitations.

Creaking noise

It is argued that rubbing artificial leather would cause more creaking noises than leather. This may be valid for inexpensive artificial leather. But an expensive patent leather will also strongly creak and well-made artificial leather creakes as real leather. This test is unsuitable for suede and nubuck and their imitations.

Labelling of Leather

Normally, one can rely on the manufacturer's labeling. For online vendors, trade fairs or shopping abroad, however, be careful. Artificial leather must be clearly marked. If this is not done, the goods can be reclaimed.

Damages

If the leather or artificial leather is damaged due to its age and use, it is usually immediately clear to the experts what material it is. Synthetic leather often breaks and the fabric appears. Leather is worn slowly from top to bottom and breaks due to aging do have a different appearance.

Material mix

In case of furniture and car interior (but also other objects), sometimes identical looking leathers and artificial leathers are simultaneously processed. Usually, the contact surfaces (seat, back, armrest) are made of genuine leather and the body and the backs of artificial leather. In such cases, it is not sufficient to test only one area.

Special features on vehicles

In almost every car there are grained surfaces that are not leather-covered. These are hard plastic parts (dashboards, steering wheels, handles etc.) or synthetic leather-covered door panels or backs and lower parts of car seats.

For a lot of models of Jaguar, American, French and Japanese car manufacutres, it is common to use genuine leather for the contact surfaces (seat, back, front of the headrest), but all other surfaces of the seat set are made of artificial leather. In contrast to the furniture sector, the qualities of the artificial leather are generally good. Incredibly robust was e.g. the MB-TEX from Mercedes, which generations of taxi drivers used to have. The new generations of imitation leather of Mercedes is called "Artico leather" with comment "man-made leather". This material description does not appear to be in compliance with EU standards.

Special features of furniture leather

Imitation leather, where it is not obvious at first glance.

Especially in the low-priced furniture segment, there is a large selection of upholstered furniture, which is completely covered with artificial leather. As with car seats, there are also furniture, where only the contact surfaces are made of genuine leather and the rest is made of artificial leather. Synthetic leather is also often used in highly frequented areas, such as waiting areas in hotels and restaurants. In such areas it is necessary to exchange more frequently because of the heavy use of the furniture and the constant need for cleaning is also easier to perform with artificial leather. In principle, this is not a quality deficiency, as long as the durability of the artificial leather lies within the expected parametres and the furniture was declared accordingly at the sale.

At first glance not recognizable as artificial leather. Reverse is textile and the material is very thin.

Artificial leather in the furniture area is always the "little brother" of genuine leather. In the case of very inexpensive imitation leather leather, unexpected early damages occurs. On the seats and arm rests in particular, the coating often breaks within the guarantee or shortly thereafter.

Typical damage to artificial leather furniture in the contact areas (seat, armrest, headrest).

3 years old synthetic leather couch. Besides the sitting area it also breaks in areas without burden of use. The artificial leather disintegrates without external influences.

Frequently, customers do not know that at least partial surfaces are made of artificial leather. Usually, this declaration appears hidden in small letters on long texts and is also often misleading explained: "textile leather", "leathertex", "leather imitation", "like leather", etc. These are always artificial leather. Dealers who do not declare the goods clearly and intelligibly should not be trusted.

Increasingly, artificial leather is offered, with leather fibers glued to the reverse. Such synthetic leather is not genuine leather.

In the furniture area is also offered an artificial leather with the name "Napalon leather". Since it is an artificial leather, the name is misleading without the indication that it is only a synthetic leather, and does not correspond to the obligation to label.

Special features of bags and suitcases

Many cheap bags and cases are made of artificial leather. But also in the highest-quality segment emerges artificial leather, which is also extremely robust. At Louis Vuittons bags, the large areas with the logos outside and the interior of suitcases are made of imitation leather.

Beautiful, but surprisingly, all the large surfaces are made of artificial leather. The handle is made off vegetable-tanned leather.

Special features of clothing

Synthetic leather is usually found in the lowest price segment in the clothing sector. Customers often do not realise that its not leather. Caution is particularly important in markets and on-line auctions. Especially in online auctions, misleading terms such as "coskin" and "textile leather" are used.

Artificial furs are often offered because genuine furs are expensive and are also critically discussed. Artificial fur is also characterized as "artificial fur" or "fourrure artificielle".

Belt and jacket look like genunine leather at first glance.

Imitation of a stingray leather at a motorcycle suit. The copy is well done and hardly distinguishable from the original. Since not declared as "stingray leather", it is also no deception of the customer.
