What Are The Types Of Artificial Leather? It Should Meet These Requirements!

Artificial leather products are now widely used, and there are many production technologies, which have derived several related leather products, including PVC leather, dry PU leather, and wet pu leather, etc., and these leather products need to meet certain requirements in the production process, and these requirements are reflected in what aspects?

What are the types of artificial leather?
1. PVC leather

The basic types of PVC artificial leather include knitted fabrics, woven fabrics and non-woven fabrics. Knitted fabrics are usually cylindrical jerseys, mainly veils, and polyester-cotton blended yarns, with a unit area of 60~300g/㎡.

Woven fabric is mainly used for bags and upper leather, generally using twill, satin cotton or canvas, with a unit area of 270~400g/㎡.

2. Dry PU leather

In the base fabric of dry PU artificial leather, the amount of raised woven fabric is larger, and its specifications are not the same. In addition, there are also non-woven fabrics, and artificial leather made from the base cloth is mostly used in shoe uppers and shoe linings, while knitted fabrics are rarely used.

3. Wet PU leather

Wet-laid PU leather mainly uses non-woven fabrics and raised fabrics. The nonwoven base fabric used as wet synthetic leather has special requirements.

The requirements that high-quality artificial leather should meet:
1. The surface of the base cloth must be smooth, and the thickness of the base cloth must be uniform and consistent without defects such as heads, pimples, holes and twists.

2. The joints of the artificial leather base cloth must be firm and flat.

3. The base fabric of artificial leather must meet the requirements of the corresponding standards.

4. The base fabric should be able to withstand the higher processing temperature during the production of artificial leather and PU leather.

5. If the fabric is a fabric, it is necessary to ensure that the strength of the warp and weft directions is close, and if it is a non-woven fabric, the strength of the vertical and horizontal directions must be consistent.
