PVC artificial leather is a kind of composite material made by combining polyvinyl chloride or other resins with certain additives, coating or laminating them on the substrate and then processing them. It is similar to natural leather and has the characteristics of softness and wear resistance.
During the production process of PVC artificial leather, the plastic particles must be melted and mixed into a thick state, and then evenly coated on the T/C knitted fabric base according to the required thickness, and then enter the foaming furnace to start foaming, so that it has the ability to process various products and different requirements of softness. At the same time, it starts surface treatment (dyeing, embossing, polishing, matte, grinding and raising, etc., mainly according to the actual product requirements).
In addition to being divided into several categories according to the substrate and structural characteristics, PVC artificial leather is generally divided into the following categories according to the processing method.
(1) PVC artificial leather by scraping method
① Direct scraping method PVC artificial leather
② Indirect scraping method PVC artificial leather, also called transfer method PVC artificial leather (including steel belt method and release paper method);
(2) Calendering method PVC artificial leather;
(3) Extrusion method PVC artificial leather;
(4) Round screen coating method PVC artificial leather.
According to the main use, it can be divided into several types such as shoes, bags and leather goods, and decorative materials. For the same type of PVC artificial leather, it can be divided into different types according to different classification methods.
For example, market cloth artificial leather can be made into ordinary scraping leather or foam leather.
