What are the production methods of PVC artificial leather

Direct coating method: The rubber compound is directly coated on the pretreated base cloth with a scraper, and then it is put into a plasticizing box for gelation and plasticization, and then the finished product is obtained by embossing, cooling and other processes. This method can produce ordinary artificial leather, film artificial leather and foamed artificial leather with various cloth bases.

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 scraper, and after gelation, the cloth base is compounded on the gelled material layer without tension, and then After plasticization, cooling and peeling from the carrier, and then post-processing, the finished product is obtained. This method is suitable for producing knitted fabric or non-woven fabric-based foam artificial leather and ordinary artificial leather.

Calendering method: According to the requirements of the formula, after measuring the resin, plasticizer and other compounding agents, put it into the kneader to mix evenly, and then pass through the internal mixer, open mixer or extruder to make plastic, and then send it to the three-roller or Four-roll calender (see Plastics are mechanically calendered into a film of the required thickness and width, and laminated with a pre-heated base cloth, and then embossed and cooled to obtain the finished product. This method can produce various artificial leathers with different cloth bases. In order to improve the bonding effect between the base fabric and the film, a layer of adhesive is often applied on the base fabric.
Extrusion bonding method: Mix resin, plasticizer and other compounding agents in a kneader evenly. After plasticizing, the extruder is extruded into a film layer of a certain thickness and width, and then preheated on a three-roller setting machine. After preheating, filming, embossing and cooling, the finished product is obtained. This method is used to manufacture thicker products, such as floor leather, conveyor belts, etc.
