1、 Classification of artificial leather

Due to the different synthetic resins used, substrate varieties, production processes, foaming and uses, artificial leather can be divided into many varieties. Here, artificial leather is classified according to the synthetic resin used, substrate, presence or absence of foaming, production process method, and purpose.

（1） Classification by synthetic resin used

1. PVC artificial leather

It is a plastic product made by coating or bonding a mixture of polyvinyl chloride resin, plasticizers, and other additives onto fabric and undergoing certain processing techniques. In addition, there are also double-sided polyvinyl chloride artificial leather with plastic layers on both sides of the substrate.

2. Polyamide artificial leather

It is a plastic product with a continuous porous structure made by coating nylon 6 or nylon 66 solution on fabric and using wet film-forming method.

3. Polyolefin artificial leather

Polyethylene artificial leather is a kind of foam artificial leather. It is a product 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 a multi-layer structure composed of a solvent based polyurethane resin solution that evaporates the solvent, resulting in a multi-layer film and a base cloth. Wet polyurethane artificial leather, on the other hand, is a multi-layer structure obtained by using solvent based polyurethane resin and water-based film-forming method, which has excellent breathability and moisture permeability, as well as continuous porous layers.
