Advantages of Pu artificial leather

Advantages of Pu artificial leather

The development of artificial leather has experienced three stages, namely, in the 1930s, PVC artificial leather coated with PVC polymer material has been appeared. It has been applied in the industrial practice in the replacement of natural leather, which is a generation of artificial leather products.

During the manufacturing process, PVC leather is mainly made of hot melt of plastic particles to paste, evenly coated on t/c knitted fabric base according to the specified thickness, and then into the foaming furnace for foaming, so that it can meet the requirements of various products and requirements of softness. Surface treatment (dyeing, embossing, polishing, extinction, surface roughing, etc.) is carried out at the same time, It is mainly carried out according to the specific product requirements).

The manufacturing process of PU leather is more complicated than that of PVC leather. As the base cloth of Pu is canvas PU material with good tensile strength, it can not only be coated on the top of the base cloth, but also include the base cloth in the middle, so that the existence of the base cloth can not be seen. The physical properties of PU leather are better than those of PVC leather, such as bending resistance, good softness, high tensile strength and air permeability.

The differences between Pu artificial leather and PVC artificial leather are mainly reflected in the following aspects:

1. Pu is softer than PVC, with good quality and toughness. It is generally used to make fabrics and can bear relatively large tensile force;

2. Pu is more expensive than PVC;

3. PVC can be torn off, but Pu can't;

4. PVC bottom cloth is generally thin and thin; PVC has more water needle cloth bottom and sweatcoat cloth bottom, while Pu has higher quality cloth bottom; The base of PVC leather is textile and knitted fabric, while the base of PU leather is non-woven fabric;

5. If you use fire, Pu taste is lighter, PVC will turn black, smell.

6. The specific gravity of PVC is larger than that of PU.

7. The texture of PVC is deep, and the foaming layer in the middle is obvious.
