To produce PVC leather, the following steps are typically involved:

1. Select a suitable grade of polyvinyl chloride (PVC) resin, which is the base material for PVC leather. The grade of PVC resin is chosen based on the desired properties and characteristics of the final product, such as color, texture, and thickness.
2. Mix the PVC resin with other ingredients, such as plasticizers, stabilizers, fillers, and pigments, to form a liquid or paste-like mixture. The proportions of the ingredients are carefully controlled to ensure the desired properties and characteristics of the final product.
3. Spread the PVC mixture onto a backing fabric, such as polyester, cotton, or nylon, using a coating machine. The backing fabric provides support and structure to the PVC leather, and can also be used to add color, texture, and pattern to the final product.
4. Dry the PVC mixture using heat, air, or infrared radiation, to remove excess moisture and solvent from the mixture. The drying process is carefully controlled to ensure the desired properties and characteristics of the final product, such as flexibility, strength, and water resistance.
5. Calender the PVC leather using a calendering machine, which applies heat and pressure to the material to smooth and compact it. The calendering process is used to improve the appearance, texture, and thickness of the PVC leather, and can also be used to add special effects, such as embossing or printing.
6. Cut the PVC leather into the desired size and shape using a cutting machine, and then attach it to the final product, such as a piece of clothing, footwear, or furniture, using heat, pressure, or adhesives. The cutting and attachment processes are carefully controlled to ensure the desired properties and characteristics of the final product, such as durability, flexibility, and water resistance.

Overall, the production of PVC leather involves a series of carefully controlled steps that are designed to ensure the desired properties and characteristics of the final product. The process is typically automated and involves the use of specialized equipment and machinery, such as coating, drying, calendering, and cutting machines.
