Regenerated skin
After crushing all kinds of animal waste and leather waste, the chemical materials are processed and manufactured. Its surface processing technology is the same as that of shaving leather and embossing leather, which is characterized by neat edges, high utilization rate and low price; However, the leather body is generally thick and the strength is poor, so it is only suitable for the production of low-cost official case, pull rod bag, ball rod cover and other shaped products and low-cost belt. The longitudinal section of the fiber structure is uniform, which can identify the solidification effect of fluid mixed fiber.
Artificial leather
Also known as imitation leather or rubber, it is the general term of PVC (artificial leather) (polyurethane resin), PU (synthetic leather) (PVC), super fiber and other artificial materials. It is made on the basis of textile or non-woven fabric by foaming or laminating of PVC and Pu with various formulations. 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 top of the base cloth, but also be included in the middle, so that the existence of the base cloth can not be seen.
The physical properties of PU leather are better than that of PVC leather, with good bending resistance, softness and tensile strength. The pattern of PVC leather is hot pressed by steel pattern roller; The pattern of PU leather is a kind of pattern paper, which is first hot pressed on the surface of semi-finished leather, and then separated from the paper leather after cooling down for surface treatment. The price of PU leather is more than twice as high as that of PVC leather. The price of PU leather with special requirements is 2-3 times higher than that of PVC leather. Generally, the pattern paper for PU leather can only be used for 4-5 times, and then it will be scrapped; The use cycle of pattern roller is long, so the cost of PU leather is higher than that of PVC leather.
Artificial leather can be made according to different strength, wear resistance, cold resistance, color, luster, pattern and other requirements. It has the characteristics of various designs and colors, good waterproof performance, neat edge, high utilization rate and low price compared with genuine leather. However, most of the artificial leather can not achieve the effect of genuine leather in handle and elasticity; If you squeeze hard, the leather won't wrinkle.
There are no pores on the surface, and the bottom plate is not animal skin. Its longitudinal section, you can see fine bubble holes, cloth or surface film and dry man-made fiber.
It is a kind of material which is very popular from the early days until now. It is widely used to make all kinds of leather products, or some genuine leather materials. Its increasingly advanced manufacturing technology is widely used in the production of double skin.
Nowadays, the artificial leather which is very similar to the real leather has been produced on the market. Its surface technology and the fiber structure of the base material almost reach the effect of real leather, but it can still be distinguished from the base material on the reverse side. Its price and domestic price of the first layer of leather is also comparable.
Generally speaking, PVC feel more hard, thick, suitable for shaping bags, furniture and so on. And Pu feel soft, thin, suitable for leisure bag, and is imitation leather production, so with leather can be better match.
As for super fiber, it's expensive and not easy to fade. But feel more hard, generally do outside the single shaped bag, sofa, car cushion, etc.
