The reverse side of the material
Heartsunleather china leather factory introduce you. Artificial leather usually has 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 real leather and also experts at first glance cannot identify the material as artificial leather. For the end user, it is therefore even more difficult to distinguish leather and artificial leather. With door panels or handbags mostly the back of the material cannot be accessed without de-assembling or damaging it. With velour fabrics (like Alcantara), it is not easy to recognise 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
When a synthetic leather is cut, the cutting edge is often smooth and clean. When leather, is cut it has an almost lint-like effect. Leather has a fibrous structure that can be seen under a magnifying glass. The grain side has a dense fibre layer and becomes more fibrous towards the centre and back. In the case of artificial leather, the top layer is very dense and without fibres and then usually a fabric. Even if there are fibres on the back, the cutting edge can be frayed and then fabric threads become visible. Sometimes the artificial leather has just a pure foam foil.
Behaviour when heated
Imitation leather melts at high heat and burns well, while leather only glows and solidifies without catching fire. Burnt artificial leather smells like burnt plastic, whereas, leather smells like burnt hair. This test is not sufficient where there is a mixture of materials.
Haptic and stretchability
Experts also note that synthetic leather is often thinner and stretches more when heated. An end user can hardly recognise this due to lack of experience. If the materials are glued on hard surfaces (e.g. steering wheels, table tops), this feature cannot be tested.
Sometimes it is argued that artificial leather feels colder than leather. But there are exceptions. Good imitations with smooth or rough surfaces can feel warmer than bad comparative leather. It is now possible to copy the natural haptic of a thick aniline leather.
It is often said that leather can be recognised 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 smells. 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.
A distinctive feature is the breathability aspect. Even a heavily coated leather has more breathability than unperforated artificial leather. In rubber boots you sweat more quickly than in waterproofed trekking boots made of leather. When you sit on synthetic leather surfaces for longer, you notice that you sweat more quickly than on real leather. But artificial leather can be micro-perforated to make it more vapour-permeable. This test would not lead to a correct result in such cases. This test is also unsuitable for suede and nubuck and their imitations.
