Leather identification can sum up in the following ways

Is characterized with aniline finished said, aniline leather surface have JingLiangLiang light, the light is very bright, but not out there, no plastic. Natural leather made of leather, cowhide is usually 5 ~ 6 mm thick, the surface is surface, organization fiber meticulous tight tight, lubrication beautiful, strength, excellent wear resistance; Layer is the suede layer, coarse fibre, gap is big, fuzzy appearance. First layer of leather than split leather appearance lubrication flat, split leather. Split leather by finishing, moving film or film Don’t see rough can make appearance, low temperature resistance is poor, but moving film leather at low temperature is used as a wrinkle. Cowhide leather on the second floor flat, no significant drawbacks, after embossing and pigskin split leather usually visible three piles of MAO cavity, it shine. Difference should note when corrected grain and positive leather, corrected grain is destroyed the original grain surface, and then press the markings, speckle varieties can be imitated cattle, sheep, pig, etc., but striped glabrous cavity, speckle is floating on the skin surface, and upper MAO cavity exists, careful investigation can be identified.

 

 

Artificial leather is on the bottom base cloth coating a layer of organic material, thin sheep (imitation leather), thickness (with foaming coating of organic materials, pressed again on the markings) two type. After synthetic leather is made of organic fiber limit, and after finishing layer embossing. Regenerated leather is the leather, leather fibre grinding slag, the adhesion, high pressure with adhesive sheet formation, and then the thickness of leather machine pills to demand, and then to finish, make it has some features, leather for bags leather pieces, a few used shoes.
