What is PU fabric? What kind of material is PU fabric?
PU is an artificial synthetic material that has the texture of genuine leather, is very strong and durable, and is cheap. The often referred to as PU leather is a kind of leather, such as PVC leather, Italian leather bran paper, recycled leather, etc.
Characteristics of natural leather and artificial leather
Characteristics of natural leather
Characteristics of natural leather Its properties are superior to other materials in that it is flexible, breathable, wear-resistant, fold-resistant, and beautiful…so it is a necessary material for high-end leather shoes. Its characteristics are:
1. The quality of natural leather parts varies greatly.
Because the skin has different functions in different parts of the animal’s body, and the production and development are also different. After being made into leather, its fiber structure, density, tear resistance, and tensile strength are different in each part. In particular, the look and feel, extended feel, flex resistance and processing properties are all different.
2. The fiber (silk pattern) structure of the site is directional.
Different parts of each piece of leather have different fiber directions.
When leather is stretched, different parts have different elongation rates.
Some force rates are different, and their elongation rates are also different, and the gap is very large.
3. Breathable.
This feature allows the wearer’s sweat to be discharged out of the shoe cavity, making the wearer feel comfortable.
4. Good heat resistance and cold resistance.
5. It has good wear resistance and stamping resistance, and is easy to process.
6. Leather is soft, tough, elastic and resistant to bending. Adapt to human physiological needs.
7. Beautiful and easy to modify and shape.
Characteristics of Artificial Leather
Any imitation leather that is artificially made and used as an auxiliary material or auxiliary material is called artificial leather. According to its structure, it can be divided into two types: synthetic leather and artificial leather.
Features of synthetic leather:
1. Good corrosion resistance. Because the surface is coated with plastic, it is not prone to chemical reactions when in contact with mild acids and alkalis. And it has anti-insect properties.
2. It has good anti-sand performance and cannot penetrate the inner layer when in contact with sand.
Therefore, when the surface is stained, wet cloth can be used to control the dock, and its luster will remain unchanged
3. The surface is smooth and the material is uniform, and there are no defects of natural leather deep in the surface. The leather surface is bright and beautiful, and the surface color and pattern can be designed artificially. And because the bottom is basically flat, the material is uniform. Therefore, it is easy to mechanize, standardize and assemble.
4. Poor air permeability. Because the fiber structure of the base is sealed by the surface plastic, it has poor air permeability compared with natural leather.
5. It is not resistant to high temperature and cold, which is determined by the properties of its material.
Characteristics of artificial leather:
Light, thin and soft, suitable for moccasins. The strength is not as good as that of full leather, and it is afraid of scratches. The upper structure has more reinforcements to make up for its shortcomings. Artificial leather has poor breathability and sweat absorption. AAGFREGRTTHR
