(Summary description)Artificial leather, plastic products similar to leather. The plastic film is rolled on the cotton cloth or the synthetic resin containing plasticizer is evenly coated on the cotton cloth and then processed. It is soft in nature and has various colors and patterns. Artificial leather is a kind of material similar to natural leather, which is a mixture of resin raw materials and other additives and obtained after certain processing. At present, the widely used resin raw materials are PVC (PVC) and polyurethane (PU). In the manufacturing process of PVC leather, the plastic particles shall be melted and stirred into a paste, evenly coated on the T / C knitted fabric substrate according to the specified thickness, and then enter the foaming furnace for foaming, so that it has the softness that can adapt to the production of various products and different requirements. The surface treatment (dyeing, embossing, polishing, matting, grinding and fuzzing, etc.) shall be carried out at the same time when it is out of the furnace, mainly according to the specific product requirements. The manufacturing process of PU leather is more complicated than that of PVC leather. Because the Pu base cloth is canvas PU material with good tensile strength, it can not only be coated on the base cloth, but also be included in the middle, so that the existence of the base cloth can not be seen outside. The physical properties of PU leather are better than those of PVC leather, with twists and turns resistance, good softness, high tensile strength and air permeability (PVC free).

Advantages of artificial leather
Artificial leather, also known as imitation leather or rubber, is the general name of artificial materials such as PVC and PU. It is made of foamed or coated PVC and Pu with different formulas on the basis of textile cloth or non-woven cloth. It can be processed according to the requirements of different strength, wear resistance, cold resistance, color, luster and pattern. It has the characteristics of a wide variety of designs and colors, good waterproof performance, neat margins, high utilization rate and relatively cheap price compared with leather, but the hand feel and elasticity of most artificial leather can not reach the effect of leather; In its longitudinal section, you can see fine bubble holes, cloth base or surface film and dry man-made fibers. It has the characteristics of a wide variety of designs and colors, good waterproof performance, neat margins, high utilization rate and relatively cheap price compared with leather, but the hand feel and elasticity of most artificial leather can not reach the effect of leather; In its longitudinal section, you can see fine bubble holes, cloth base or surface film and dry man-made fibers. It is a very popular kind of material in the early days until now. It is widely used to make all kinds of leather products or some leather materials. Its increasingly advanced production technology is widely used in the processing and production of two-layer leather. Nowadays, the artificial leather with the characteristics very similar to leather is available in production. Its surface technology and the fiber structure of the base material almost reach the effect of leather, and its price is similar to that of domestic first layer leather.

Comparison of properties between PVC artificial leather and Pu artificial leather
Comparison of characteristics between PVC artificial leather and Pu artificial leather the first generation of artificial leather is PVC (PVC), which is cheap and has a certain natural leather texture, but it has the disadvantages of poor weather resistance, stiff hand feel and poor softness. It is mainly used in the field of low-end luggage, shoes and balls. The second generation product is pu (polyurethane), which originated from the large-scale application of polyurethane materials in the 1940s. It has the advantages of soft gloss, soft hand feeling, strong leather feeling and good cold resistance. It is widely used in the fields of clothing, furniture and medium and high-grade shoes. The pattern of PVC leather is hot pressed by steel pattern roller; The pattern of PU leather is first hot pasted and pressed on the surface of semi-finished leather with a kind of pattern paper, and then separated the paper leather after cooling down for surface treatment. The price of PU leather is more than twice that of PVC leather, and the price of PU leather with special requirements is 2-3 times higher than that of PVC leather. Generally, the pattern paper required for PU leather can only be used for 4-5 times and will be scrapped; The service cycle of patterned roller is long, so the cost of PU leather is higher than that of PVC leather. The scope of application of the two materials is also different. In terms of footwear, PVC leather is mostly used in lining or non weight bearing parts, or in the manufacture of children's shoes; PU leather can be applied to the fabric of shoes or parts bearing weight. In terms of bags, PVC leather is more suitable. This is because the items in the bag are different from the feet in shoes and will not emit heat; No need to bear personal weight. It is easy to distinguish between Pu and PVC. From the corners, the bottom cloth of Pu is much thicker than PVC, and there are also differences in hand feeling. Pu feels softer; PVC feels harder; You can also burn it with fire. The taste of Pu is much lighter than that of PVC.
