Along with the science and technology development, the imitation leather technology day by day is also mature, the product quality enhances greatly, specially is imitating the dermis aspect, may confuse falsehood with the truth, in the permeability, the flexibility, feel and the outward appearance and so on many aspects is all similar with the natural leather, but the price by far is lower than the natural leather actually, thus, for sharpens our resolution capability, presently introduced some simple and the direct method supplies the reference.

　　The visual distinction law should from aspects and so on leather pattern, pore distinguish, may see in the natural leather surface the pattern, the pore exist truly, and distributes non-uniform, the reverse side has the animal fiber, the profile, the level may distinguish obviously, the lower level has the animal fiber, blows with the fingernail tries to be able to appear the leather fiber to raise up, some carding feeling, the few textile fibers also may fall down, but synthesizes the leather reverse side to be able to see the fabric, the side non-animal fiber, the general epidermis does not have the pore, but somewhat has imitates the skin man-made pore, can have not the obvious pore existence, some patterns are not obvious, or has the regular man-powerThe manufacture pattern, the pore quite is also consistent.

　　The feel distinction law dermis feel rich elasticity, can appear the leather frontage downward bend 90 degrees about the nature to fold, distinguishes the bend different spot, produces fold thick thin, how many, has the obvious non-uniformity, basic may recognize this is a dermis. Because the real leather has natural the non-uniform fiber structure to constitute, therefore forms the bulging trace performance also has the obvious non-uniformity. But synthesizes the leather feel plastic, the reply is likely bad, the bend gets down fold thick thin how many to be all similar.

　　The smell distinction law natural leather has a very thick superficial knowledge taste, even if process processing, the flavor is also obvious, but imitation leather product, then has the plastic flavor, non-superficial knowledge flavor.

　　The burning distinction law mainly is smells the burnt fetid odor and looked ashes condition, when natural leather burning can send out the smell which hair scorches, fires the ashes general brittle become powdery, but the imitation leather, after burning the flame is also prosperous, the contraction is rapid, and has the stock very ill-smelling plastic flavor, after the fever becomes sticky, after cooling can harden turns massive.
