Classification of leather fabrics: genuine leather, ultra-fiber leather, environmentally friendly leather, western leather, imitation leather

Imitation leather is PVC plastic, but the surface is made of leather grain, the quality of imitation leather is determined by the thickness, general imitation leather thickness 0.7mm, there are 1.0mm thick 0.7mm, 1.2mm 2.Omm, 1.5mm, leather, the thicker the better. The color of imitation leather is very important and must be the same color or close to the dermis. If the difference is relatively large, it will seriously affect the quality of furniture.
Xipi is a kind of artificial leather, mainly made of PVC, thicker than 1.0MM.
Environmental protection leather is a new type of artificial leather, which feels very soft and the skin pattern is similar to that of genuine leather.
Super-fiber leather, also known as super-fiber leather, is the best artificial leather, the skin pattern is very similar to the dermis, the feel is a little hard, it is difficult for outsiders to tell whether it is dermis or recycled leather.
Ultra-fine leather, the full name of ultra-fine fiber simulated sofa leather, also known as recycled leather, belongs to a newly developed high-grade leather in synthetic leather, not real leather. Because of its cold resistance, air permeability, aging resistance, soft texture and beautiful appearance, it has become an ideal choice to replace human leather.
The natural dermis is made of many collagen fibers of different thickness, which is divided into two layers: the granular layer and the reticular layer, and the thicker collagen fibers of the reticular mountain.

Because the surface layer of ultra-fiber leather is composed of polyamine vinegar layer which is similar to the grain layer of natural dermis, and the bottom layer is made of ultra-fine fiber non-woven fabric, the structure is very similar to the reticular layer of natural dermis. Therefore, the structure and properties of ultra-fiber leather and natural dermis are very similar.

Compared with natural dermis, ultra-fiber leather mainly has the following characteristics:

1. The fastness to folding is comparable to that of natural leather. The bending at room temperature reaches 200000 times and the low temperature (- 20 ℃) has 30 000 times without cracks (good temperature resistance and mechanical properties).
two。. The elongation is moderate (good skin feel).
3. Tear strength and peel strength are higher (wear resistance, tear force, tensile strength are high).
4. There will be no pollution from production to use, and the environmental protection performance is superior. The appearance effect of ultra-fiber leather is most like real leather, and its thickness uniformity, tear strength, color brightness and leather surface utilization are better than natural leather, which has become the development direction of contemporary synthetic leather. If there is dirt on the surface of ultra-fiber skin: scrub with high-grade gasoline or clean water, do not scrub with other organic solvents or substances with alkaline, in case the quality is stolen. The use conditions of superfiber skin: the heat setting temperature is no more than 25 minutes at 100 ℃, no more than 10 minutes at 120 ℃, and no more than 5 minutes at 130 ℃.
