What is leather, leather, PU, PVC, super fiber leather fabric?

"Genuine leather" is a common word in the leather products market. It is mainly made of animal skin. There are many kinds of genuine leather with different structure, quality and price. Therefore, leather is not only the general name of all natural leather, but also a vague mark in the commodity market. From a physiological point of view, any animal skin has hair, epidermis and dermis. Because the dermis contains reticular small fiber bundles, it has considerable strength and permeability. The epidermis is located under the hair, close to the top of the dermis, and consists of epidermal cells of different shapes.

Microfiber leather

The matching leather is made by smashing the leftover material of the first layer of cow hide, adding polyethylene material to re fit it, and then spraying chemical materials on the surface or coating PVC and Pu films. It maintains the characteristics of natural elasticity and process plasticity, but its strength is poor, and it will produce errors such as lines and colors with the main skin, resulting in poor visual effect and high cost.

PVC, full name polyvinyl chloride, is mainly composed of PVC. In addition, other ingredients are added to enhance its heat resistance, toughness, ductility, etc. Different additives can be added according to different uses, and PVC plastics can present different physical and mechanical properties. A variety of hard, soft and transparent products can be made by adding proper amount of plasticizer into PVC resin. There are many kinds of plasticizers, and their toxicity data are very different. The advantages are low price, rich colors and various patterns, while the disadvantages are that it is easy to become hard and brittle.

Pu is a kind of artificial synthetic material, which has the texture of genuine leather and is very durable. It is different from artificial leather. PU synthetic leather is used to replace PVC artificial leather, its price is higher than PVC artificial leather. In terms of chemical structure, it is closer to leather fabric. It does not use plasticizer to achieve soft properties, so it will not harden and become brittle. At the same time, it has the advantages of rich colors and various patterns. The price is cheaper than leather fabric, so it is welcomed by consumers.

Microfiber leather is the abbreviation of superfine fiber polyurethane synthetic leather. It is the third generation of artificial leather after PVC synthetic leather and traditional PU synthetic leather. The base fabric of super fiber leather is superfine fiber, not ordinary knitted fabric or woven fabric, but fully simulates the structure of natural leather, so it has more excellent properties than ordinary artificial leather, and is closer to the natural fiber of leather in structure. To some extent, some of its properties even surpass that of leather.

Zero solvent PU leather -- different from the traditional production process, zero solvent PU leather does not need to add any low boiling point organic solvent in the production process, which makes the product very environmentally friendly and healthy, tasteless and non-toxic, and has excellent weather resistance, wear resistance, antistatic, anti UV, low fogging value and other properties. The solid content of solvent-free polyurethane resin is 100%.
