< /p >

< p > (two) substitute leather: < /p >

< p > 1, regenerated leather: the leftover bits and pieces of the leather are crushed into fibrous form, together with plant fiber adhesive and various kinds of compounding agents, pressed and molded, used for touring shoes and belts.

Because the raw material of regenerated leather is mainly the waste of natural leather, regenerated leather has certain hygroscopicity, permeability and permeability, and also has certain heat resistance, abrasion resistance and elasticity, but its strength is small and tear property is poor.

< /p >

< p > 2, artificial leather: synthetic resin based on textile or knitted materials, which belongs to imitation leather products. The coating material is mainly PVC resin, its luster is brighter, its color is bright and varied, and its surface has no scar marks.

< /p >

< p > 4, PU leather: (Gao Ji) the exterior coating is highly emulation, and can emit various patterns and bright colors, but it has poor hygroscopicity, poor temperature difference and tear. It is easy to expand when incisions, but the quality is uniform, and the surface is free from disability and moldy. It has certain resistance to water and solvent.

< /p >

< p > three, all kinds of leather products should meet the quality standard < /p >.
