The main difference between PU leather and man-made leather is that PU leather is called two-layer cow leather. At the same time, it is also called artificial leather with cow leather fiber. It is not the leather growing on cattle. Therefore, the cow leather can be made by adding polyethylene material after the leftover material is broken, and then spraying chemical materials on the surface and covering with PVC and Pu films. In terms of artificial leather, it is mainly based on textile cloth and non-woven cloth. It is mainly made by coating and foaming PVC and Pu with different formulas,.
The characteristics are also relatively different, mainly in the aspect of PU leather. The folding fastness is very comparable to that of natural leather, and the bending degree can reach about 200000 times at room temperature without cracks and low temperature. When there are no cracks after 30000 times of bending, the mechanical property and temperature resistance are very good, and the elongation is very moderate, At the same time, the peel strength and tear strength are higher, the tear strength, wear resistance and tensile strength are significantly higher, and the environmental protection performance is obviously better. In terms of artificial leather, there are more varieties of designs and colors, better waterproof performance, more neat edges, higher utilization rate, and the price will be cheaper than leather.
In terms of application, PU leather is mainly used in the manufacture of clothing, vehicles, bags, footmats, sofas, etc. in the early stage of artificial leather, a kind of material is popular, which is mainly used to make all kinds of leather products.
Super fiber leather is mainly one of the mainstream leather, and compared with many sofa and other furniture, it will use the leather material of super fiber leather. In terms of advantages, as an artificial leather, super fiber leather mainly has no pores, so its texture will be more regular and neat, and it will be more waterproof. In fact, it is easier to remove oil stains when we scrub with household alcohol or water, And the resistance to acid and alkali is not low, and mildew is not easy to occur. Because it is man-made, the super fiber leather is very excellent in flexibility and wear resistance. The air permeability and moisture absorption are very close. After touching, it also appears very smooth and soft, and the hand feel is more comfortable. Microfiber leather has better shaping than natural leather. At the same time, it is not easy to deform after encountering water. In terms of color brightness, compared with natural leather, it has more choices, and there is no fat flavor of natural leather.
