There are many classifications of artificial leather. According to different directions, artificial leather can be subdivided. So what are the common artificial leather classifications? Which are artificial leather? The editor sorted out the detailed classification of artificial leather, let’s take a look What are the classifications of common artificial leathers? Which ones are artificial leathers? First, according to the base material classification
is divided into cotton cloth base, synthetic fiber base and fiber base according to the class of matrix material. The cotton cloth base includes plain cloth, bleached cloth, dyed plain cloth-based artificial leather, canvas-based artificial leather, knitted cloth-based artificial leather and raised cloth-based artificial leather. Synthetic fiber bases include nylon spun polyurethane artificial leather and wet single-coated polyurethane artificial leather; fiber bases include paper Base polyvinyl chloride artificial leather and non-woven fabric-based artificial leather.
2. Classification by production method
1. Direct application of artificial leather
The rubber material is directly applied to the pretreated base fabric with a scraper, and then put into a plasticizing box for gelation and plasticization, and then through embossing and cooling processes, the finished product is obtained.
2. Transfer coating method artificial leather
Transferred scraping method is also called indirect scraping method. The carrier used is release paper or stainless steel belt, so it is divided into release paper method and steel belt method.
3. Calendering and pasting legal artificial leather
According to the requirements of the formula, the resin, plasticizer and other compounding agents are metered and mixed evenly in a kneader, and then plasticized by an internal mixer or extruder, and then sent to a two-roll or four-roll calender. The film of the required thickness and width is attached to the pre-heated base fabric, then embossed and cooled to obtain the finished product.
4. Squeeze out legal artificial leather
The resin, plasticizer and other compounding agents are mixed uniformly in a kneader, and after being plasticized, they are extruded into a film with a certain thickness and width through an extruder, and then pasted with the preheated base cloth on the two-roll setting machine After preheating, filming, embossing, and cooling, the finished product is obtained.
5. Rotary net coating method artificial leather
Using a spatula, the emulsion polyvinyl chloride paste resin prepared by the formula is slowly coated on the cloth base to produce artificial leather through a rotary screen.
6. Wet artificial leather
The law is for the next law. The definition can be found in polyphthalamide artificial leather. This method is suitable for producing wet polyurethane artificial leather, polyamide artificial leather, etc.
