1, natural leather is irregular shape, thickness is not uniform, the surface is often more or less, there was some light or heavy physical defects, with varying degrees of its surface smooth and detailed, General side abdominal relaxation, all material upper leather with visible pores and patterns, leather lining generally tuft. The synthetic leather uniform thickness, smooth surface, no natural defects, its pores and patterns are very uniform, no tuft leather in general.
2, for finished leather, leather is more difficult to distinguish between true and false, especially the small size, compact structure, can not see the inside of leather products, the identification of these products is: look at the appearance, texture, uniformity, no disability, No coarse grain, without any defects may be artificial leather; while there are some differences in the texture of leather, leather products, especially primary and secondary parts of the binding site at the difference should be obvious more. Then carefully observed distribution and pore shape; natural leather and deep holes should not be more clear, slightly tilted; rather plain vertical pores may be modified synthetic leather upper leather. In addition, from the cross section view, natural leather fiber cross-section has its own characteristics, there are layers of fiber thickness variations. The basic synthetic leather uniform fiber layers, the surface layer of the plastic film was. shoes factory3, drip test: absorbent apparent as natural leather, on the contrary may be leather.
4, the tension and elasticity test: natural leather has good elasticity and tension, whereas that is leather.
5, inflatable test: the opposite can be aligned with the saliva leather blowing in front of leakage, precisely because of the dermis with this "anti-reverse performance," When you wear leather, the cold effect is very obvious, and the formation of good permeability, which fully reflects the value of the dermis.
6, visual identification method: First, should leather patterns, pores, etc. to identify, in a natural leather surface you can see the pattern, the existence of pores and unevenly distributed, there is a negative animal fiber, side section, the level of clearly identifiable , the lower animal fiber, with a fingernail scratch test will appear ruffled leather fibers, there is a feeling of napping, a small amount of fiber can also be falling down, but opposite to see the fabric of synthetic leather, side no animal fibers, usually skin without pores However, there are some artificial leather pores, pores will be obvious presence, some patterns are not obvious, or have more regular artificial patterns, pores are fairly consistent. shoes manufacturer7, feel identification method: Second hand leather elastic, the leather face down bent 90 degrees occur naturally folds, respectively, different parts of bending, the resulting folds thickness, how much there is obviously uneven, which can be leather that this is because the true nature of the leather with natural uneven fibrous tissue, thus forming crease lines there was a marked uneven. The synthetic leather feel like plastic, recovery is poor, bend down how many folds thickness is similar.
8, odor identification method: natural leather coat with an very strong flavor, even after treatment, the taste is more pronounced, leather products, there are stocks of plastic taste, no smell of fur.
9, combustion identification method: mainly sniffing coke smell and look ashes status, natural leather burns with an odor of burning hair, burning ashes generally breakable into powder, and leather, the combustion flame is also more Wang, shrink rapidly, and there are shares smelled plastic taste, after burning sticky, stiff after cooling will become lumpy.women shoes manufacturer
