Today we will come to understand the basic knowledge of PP yarn.
The performance characteristics of PP yarns are as follows:
Form: The longitudinal direction of the PP yarn is straight and smooth, and the cross section is round;
Density: The biggest advantage of PP yarn is its light weight. Its density is only 0.91g/cm3, which is the lightest of the common chemical fibers.
Strong stretchability: PP yarn has high strength, large elongation, high initial modulus and excellent elasticity. Therefore, polypropylene has good wear resistance. In addition, the wet strength of the PP color yarn is substantially equal to the dry strength.
Hygroscopicity and dyeability: PP yarns have little hygroscopicity and are almost non-hygroscopic. The moisture regain under atmospheric conditions is close to zero. However, it has a wicking action and can transfer water vapor through the capillary in the fabric, and does not have any absorption by itself.
Acid and alkali resistance: PP color yarn has good chemical resistance. In addition to concentrated nitric acid and concentrated caustic soda, PP yarn has good resistance to acid and alkali.
Light resistance: PP color yarn has poor light resistance, poor thermal stability, easy aging, and is not resistant to ironing. However, it is possible to improve the anti-aging property by adding an anti-aging agent at the time of spinning. In addition, the PP yarn has good electrical insulation, but it is easy to generate static electricity during processing.
The performance of PP yarn is superior, and it is a kind of chemical fiber material that is often used in our life and production.
Dongguan Donggang Chemical Fiber Co., Ltd. currently has 16 polypropylene filament production lines, which has formed an annual production capacity of 20,000 tons of PP yarn, and its market share ranks first in the same industry.
Donggang Chemical Fiber has always adhered to the road of scientific and technological development, constantly improving the company's management level and product technology content, and enjoys a high reputation in the international market.
