Description

technical field

[0001] The invention relates to the technical field of floor leather, in particular to the technical field of regenerated leather prepared by a non-woven fabric process. Background technique

[0002] Polyvinyl chloride (PVC) floor leather is a floor coil produced by coating or calendering on the sheet-like continuous base material with PVC resin as the main raw material and adding appropriate additives. The sheet-like continuous base material is foamed High-quality PVC material, the thickness generally accounts for more than 80% of the finished floor leather. The PVC foaming process is complicated, and a large amount of plasticizers, stabilizers, antioxidants and other additives need to be added. The complexity of raw materials directly determines the safety hazards of PVC floor leather products, which can easily cause excessive volatilization of organic components and Heavy metal pollution.

[0003] Genuine leather fiber regenerated leather is a green and ...
