What are the classifications of artificial leather?

　　I. Classification of artificial leather

　　Because of the different synthetic resins used in artificial leather, the different types of substrates, the different production processes, the different foaming and uses, artificial leather can be divided into many types. Here, artificial leather is categorized according to the synthetic resin used, base material, with or without foam, production process method and usage.

　　(I) Classification according to the synthetic resin used

　　1、Polyvinyl chloride artificial leather

　　It is a mixture of polyvinyl chloride resin, plasticizers and other agents, coated or laminated on fabrics, made of plastic products through certain processing techniques. In addition, there are also double-sided PVC artificial leather with plastic layers on both sides of the base material.

　　2、Polyamide artificial leather

　　It is coated with nylon 6 or nylon 66 solution on the fabric, and made into plastic products with continuous porous structure by wet film forming method.

　　3、Polyolefin artificial leather

　　Polyethylene artificial leather is a kind of foam artificial leather, which is made of low-density polyethylene resin as the main raw material, mixed with modified resin, cross-linking agent, lubricant, foaming agent and other components.

　　4、Polyurethane artificial leather

　　Polyurethane artificial leather is divided into dry polyurethane artificial leather and wet polyurethane artificial leather. The so-called dry polyurethane artificial leather refers to the solvent-based polyurethane resin solution volatilization of the solvent, the multilayer film plus the backing fabric and the multilayer structure. Wet polyurethane artificial leather, on the other hand, is a multilayer structure with good air permeability and moisture permeability and a continuous porous layer obtained by applying a solvent-based polyurethane resin to a film-forming method in water.

　　In addition to the above four main artificial leather, there are also polyurethane-polyvinyl chloride composite artificial leather, rubber-plastic nylon canvas leather and so on.
