1. Classification of Artificial Leather
Due to the different synthetic resins, types of substrates, production processes, whether foamed or not, and different applications used in artificial leather, it can be divided into many categories. Here, artificial leather is classified according to the synthetic resins used, substrates, whether foamed or not, production processes, and Applications.
(1) Classification by Synthetic Resins Used
1. Polyvinyl Chloride Artificial Leather
It is a mixture made of polyvinyl chloride resin, plasticizers, and other additives, coated or bonded onto fabric, and produced through a certain processing method into a plastic product. In addition, there is also double-sided polyvinyl chloride artificial leather with plastic layers on both sides of the substrate.
2. Polyamide Artificial Leather
It is made by coating nylon 6 or nylon 66 solution onto fabric, using a wet film formation method to create a plastic product with a continuous porous structure.
3. Polyolefin Artificial Leather
Polyethylene artificial leather is a type of foam artificial leather, made primarily from low-density polyethylene resin, mixed with modified resins, crosslinking agents, lubricants, foaming agents, and other components.
4. Polyurethane Artificial Leather
Polyurethane artificial leather is further divided into dry method polyurethane artificial leather and wet method polyurethane artificial leather. The so-called dry method polyurethane artificial leather refers to the multi-layer structure formed by evaporating the solvent from the solution of solvent-based polyurethane resin, resulting in a multi-layer film combined with a base fabric. Wet method polyurethane artificial leather is obtained by using a water-based film formation method with solvent-based polyurethane resin, which has good breathability and moisture permeability, while also having a continuous porous layer multi-layer structure.
In addition to the four main types of artificial leather mentioned above, there are also polyurethane-polyvinyl chloride composite artificial leather, rubber-plastic nylon canvas leather, etc.

Advantages of artificial leather
Artificial leather, also known as synthetic leather or leatherette, is a general term for synthetic materials such as PVC and PU. It is made by processing various formulations of PVC and PU through foaming or coating on a textile or non-woven fabric base, and can be manufactured according to different requirements for strength, abrasion resistance, cold resistance, color, gloss, patterns, and designs.

Comparison of PVC Artificial Leather and PU Artificial Leather Production Processes
Artificial leather, a plastic product similar to leather. It is made by rolling plastic film onto cotton fabric or evenly coating synthetic resin containing plasticizers onto cotton fabric, followed by processing. It has a soft texture and comes in various colors and patterns.

Comparison of the characteristics of PVC artificial leather and PU artificial leather
The first generation of synthetic leather products is PVC (PVC), which is inexpensive and has a certain texture similar to natural leather, but it has disadvantages such as poor weather resistance, a stiff feel, and poor softness. It is mainly used in low-end bags, shoes, and sports balls. The second generation of products is PU (polyurethane), which originated after the large-scale application of polyurethane materials in the 1940s. It has advantages such as a soft luster, a soft feel, a strong leather-like sensation, and good cold resistance, and is widely used in clothing, furniture, and mid-to-high-end footwear.

Introduction to the Advantages of PU Artificial Leather
The development of synthetic leather has basically gone through three stages. In the 1930s, PVC synthetic leather made from PVC polymer materials appeared, achieving practical industrial applications as a substitute for natural leather. This is the first generation of artificial leather. In the manufacturing process of PVC leather, plastic particles are first thermally melted and mixed into a paste, then evenly coated on a T/C knitted fabric base according to the specified thickness. It then enters the foaming furnace for foaming, giving it the softness needed to adapt to the production of various products with different requirements. Surface treatment (dyeing, embossing, polishing, matting, and brushing) is carried out simultaneously as it comes out of the furnace, mainly according to the specific product requirements.

Distinguish between synthetic leather and genuine leather products
Artificial leather products have already covered all aspects of life, including seats, sofas, leather shoes, bags... Artificial leather products can be said to be everywhere. However, many people are still unclear about the characteristics of artificial leather and the differences from genuine leather. Although the current trend is for artificial leather to further develop and genuine leather products to lose market share, it doesn't hurt to understand a bit more.
