What kind of fabric is pu
PU is the abbreviation of polyurethane in English, and the chemical name in Chinese is “polyurethane”. It is a polymer material. Polyurethane is an emerging organic polymer material, known as the “fifth largest plastic”, and is widely used in many fields of the national economy because of its excellent performance. Product application fields include light industry, chemical industry, electronics, textile, medical care, construction, building materials, automobiles, national defense, aerospace, aviation, etc.
PU coated on the surface of fabrics first appeared on the market in the 1950s. In 1964, the American DuPont Company developed a PU for shoe uppers. Synthetic Leather. After a Japanese company established a production line with an annual output of 600,000 square meters, after more than 20 years of continuous research and development, PU synthetic leather has grown rapidly in terms of product quality, variety, and output. Its performance is getting closer and closer to natural leather, and some properties even exceed natural leather, reaching the point where it is difficult to distinguish between genuine and fake natural leather. It occupies a very important position in human daily life.

Frequently asked questions about PU fabrics
Question: What is the difference between PU and PVC fabrics
Answer: Most people refer to synthetic leather other than genuine leather such as PVC and PU leather collectively. Artificial leather or imitation leather. PVC and PU are both polyvinyl chloride (a type of plastic), but the manufacturing processes of these two products are different.
During the manufacturing process of PVC leather, plastic particles must be hot-melted and stirred into a paste, and then evenly coated on the T/C knitted fabric base according to the specified thickness. Then enter the foaming furnace for foaming, so that it has a softness that can adapt to the production of various products and different requirements. Surface treatment (dying, embossing, polishing, matting, grinding and raising) is performed at the same time as it comes out of the oven. etc., mainly based on specific product requirements).
The manufacturing process of PU leather is more complicated than that of PVC leather. Since the base fabric of PU is canvas PU material with good tensile strength, in addition to being coated on In addition to the top of the base fabric, the base fabric can also be included in the middle so that the existence of the base fabric cannot be seen from the outside. The physical properties of PU leather are better than PVC leather, including resistance to bending, good softness, high tensile strength, and breathability (not available in PVC). The pattern of PVC leather is hot-pressed by a steel pattern roller; the pattern of PU leather is hot-pasted on the surface of the semi-finished leather with a pattern paper, and then the paper leather is separated after it cools down to make the surface. deal with. The price of PU leather is more than double that of PVC leather, and the price of PU leather with certain special requirements is 2-3 times higher than that of PVC leather. Generally, the pattern paper required for PU leather can only be used 4-5 times before being scrapped; the pattern roller has a long service life, so the cost of PU leather is higher than that of PVC leather.
Question: How to wash PU fabric
Answer: Cleaning method:
1. Clean with water and detergent, avoid scrubbing with gasoline
p>
2. Cannot be dry cleaned
3. Can only be washed with water, and the washing temperature cannot exceed 40 degrees
4. Do not expose to sunlight
5. Do not come into contact with some organic solvents
6. PU leather jackets need to be hung in bags and cannot be folded
