Polypropylene Filament Products

Today for everyone, here are some pictures of finished products of polypropylene filament:


In addition, Yinxiang has the following five requirements for polypropylene filament products:

1. Form: The longitudinal plane is straight and smooth, and the cross section is round.

2. Density: light texture, density is 0.91g/cm (Polypropylene fibers are the lightest chemical fibers in common use, so the same weight of polypropylene fibers can get a higher coverage area than other fibers.)


3. Strength and elongation: high strength, elongation, high initial modulus, excellent elasticity. Yinxiang's 

polypropylene fiber has good wear resistance and wet strength is equal to dry strength. It is an ideal material for making fishing nets and cables.

4. Hygroscopicity and dyeability: It is required that the moisture regain under general atmospheric conditions be close to zero.(The company's polypropylene fibers have little moisture absorption, almost no moisture absorption, but it has core absorption, can transfer water vapor through capillaries in the fabric, but it does not absorb any of its own. The dyeing property of polypropylene fibers is poor and the chromatogram is incomplete, but this problem has been solved by the method of original solution



5. Acid and alkali resistance: excellent chemical corrosion resistance. The company's polypropylene fiber has good resistance to acid and alkali, so it is suitable for use as filter materials and packaging materials.

However, polypropylene fibers have poor light resistance, poor thermal stability, easy aging and ironing resistance. To solve this problem, the company improves its anti-aging performance by adding anti-aging agent in spinning.
