Artificial leather
Artificial leather is a composite material that combines fiber and plastic. The current artificial leather is mainly PVC artificial leather.
The artificial leather has the characteristics of soft texture, elasticity, high mechanical strength, acid and alkali resistance, non-flammable, easy to wash, bright color and various patterns, so it is widely used. Often used to make clothing, hats, gloves, shoes, sofas, chairs and other covering materials.
Synthetic Leather
The surface of the synthetic leather is a polyurethane resin. It is a composite material formed by coating a polyurethane microporous elastomer on a composite fiber knitted fabric or a non-woven fabric.
Synthetic leather has the characteristics of oxidation resistance, wear resistance and oil resistance. Its mechanical strength, wear resistance and elasticity are better than artificial leather; its permeability and moisture permeability are close to natural leather; its surface hardness is high, it is not easy to be worm, mildew, and water resistant. Good oil resistance; stable product size, not easy to deform, soft texture at low temperature; product appearance is bright, beautiful, easy to maintain, durable. Therefore, it is extremely versatile and can replace natural leather production boxes, bags, clothes, hats and other leather products, and is widely used as a raw material for shoes.
