Including base fabric treatment, rubber preparation, coating, bonding, gelation, surface treatment, embossing, cooling, winding and other processes. There are 4 main production methods.
Direct coating method:
The rubber material is directly coated on the pretreated base fabric with a spatula, and then put into a plasticization box for gelation and plasticization, and then undergoes processes such as embossing and cooling to obtain the finished product. This method can produce all kinds of cloth-based ordinary artificial leather, film artificial leather and foam artificial leather.
Transfer coating method:
Also known as indirect coating method. The paste is coated on the carrier (release paper tape or stainless steel tape) with a reverse roller or a doctor blade, and after gelation, the cloth base is compounded on the gelled layer without tension, and then After plasticizing, cooling and peeling from the carrier, and then post-processing, the finished product is obtained. This method is suitable for the production of knitted fabric or non-woven fabric-based foam artificial leather and ordinary artificial leather.
Calendering is legal:

According to the requirements of the formula, weigh the resin, plasticizer and other compounding agents, put them into the kneader and mix them evenly, and then send them to the three-roller or four-roller calender after being mixed with an internal mixer and an open mill or extruder. (See the plastic machine calendered into a film with the required thickness and width, and bonded with the pre-heated base fabric, then embossed and cooled to obtain the finished product. This method can produce various artificial leathers with different fabric bases. In order to improve the base fabric For the bonding effect with the film, a layer of adhesive is often applied to the base fabric first.
Squeeze out legal:
The resin, plasticizer and other compounding agents are mixed uniformly in a kneader. After refining, they are extruded into a film with a certain thickness and width by the extruder, and then laminated with the preheated base fabric on a three-roller setting machine After preheating, filming, embossing, and cooling, the finished product is obtained. This method is used to make thicker products, such as floor leather, conveyor belts, etc.
