Do the abbreviations of PU and SP fabrics refer to spandex?

No. PU is the abbreviation of poly urethane, and its Chinese chemical name is polyurethane. SP is the abbreviation of Spendex, and the chemical Chinese name is polyurethane fiber, which is the abbreviation of spandex.

The leather of PU leather is composed of polyurethane, which is widely used in the decoration of clothes, shoes, bags, vehicles and furniture. It has been more and more recognized by the market, and its quantity, variety and application range are beyond the satisfaction of traditional natural leather.

Spandex is an elastic fiber. Spandex is generally composed of multiple filaments, generally 10d/ root, and now there are 15d/ root, or even 20D/ root. The less the theoretical number, the better the uniformity. DMAC, the production solution of dry spinning, is harmful to human liver because there is less chance of morphological overlap, and the content of 10d/ root is generally controlled at 0.5mg/kg.

Extended data:

In our country, people are used to calling the artificial leather made of PU resin as PU artificial leather. The artificial leather made of PU resin and non-woven fabric is called PU synthetic leather. The cleaning method is as follows:

4, can not be exposed to the sun.

5. Don't touch some organic solvents.

6.PU leather clothes need to be collected in bags and cannot be folded.

Spandex has excellent elasticity, but its strength is 2 ~ 3 times higher than that of latex yarn, and it is more resistant to chemical degradation and has finer linear density. Spandex has good seawater resistance, dry cleaning resistance, acid and alkali resistance, sweat resistance and wear resistance.
