What is polypropylene yarn ?

The chemical molecules of PP yarn are also very different, which is composed of polypropylene yarn .

The PP gauze has good heat resistance. Its density is only 0.91g/cm3. It is a variety of mild density in common chemical fibers. Therefore, the same weight patellar is higher than other fibers.

Regarding the introduction of polypropylene yarn , let's talk about its advantages.

polypropylene yarn :

1. polypropylene yarn form: The vertical surface of Plerontal is straight and smooth, and the cross section is round.

2. polypropylene yarn density: The advantage of large pallin is light texture, and its density is only 0.91g/cm3.

3. PP yarn strong extension: The strength of the pallonium wire is high, the extension is growing, the initial mode is high, and the elasticity is excellent. Therefore, the abrasion resistance is good. In addition, the wetness of Pthi Pleu is basically equal to dryness.

4. PP gauze moisture absorption and dyeing: The hygroscopic absorbent of Polypropylene is very small, almost no hygroscopic, and the recovery rate under the condition of a single atmosphere is close to zero. However, it has a core suction effect. It can pass the water vapor through the capillary in the fabric, which does not have any absorption effect.

5. PP gauze resistant alkali resistance: Polypropylene has good chemical resistance. In addition to concentrated nitric acid, thick sodium, palloprine has good resistance to acid and alkali.

6. PP gauze light resistance: Pleellastate has poor light resistance, poor thermal stability, easy aging, and not resistant to ironing. However, it can improve its anti -aging performance by adding anti -aging agents during spinning. In addition, the electrical insulation of Pthi Pleuria is good, but it is easy to generate static electricity during processing.
