Features of polypropylene 1000D industrial yarn
1. Form: The longitudinal plane of polypropylene fiber is straight and smooth, and the cross section is round.
2. Density: The biggest advantage of polypropylene fiber is its light texture. Its density is only 0.91g/cm3, which is the lightest variety among common chemical fibers. Therefore, polypropylene fiber with the same weight can obtain a higher coverage area than other fibers.
3. Strength and elongation: Polypropylene fiber has high strength, elongation, high initial modulus and excellent elasticity. Therefore, polypropylene fiber has good wear resistance. In addition, the wet strength of polypropylene fiber is basically equal to the dry strength, so it is an ideal material for making fishing nets and ropes.
4. The hygroscopicity of polypropylene fiber and dyed polypropylene fiber is very small, almost no hygroscopicity, and the moisture regain under general atmospheric conditions is close to zero. However, it has wicking effect and can transfer water vapor through the capillary in the fabric, but it does not have any absorption effect. Polypropylene fiber has poor dyeability and incomplete chromatography, but the method of original solution coloring can be used to make up for the deficiency.
5. Acid and alkali resistant polypropylene fiber has good chemical corrosion resistance. In addition to concentrated nitric acid and caustic soda, polypropylene fiber has good resistance to acid and alkali, so it is suitable for use as filter material and packaging material.
6. Polypropylene fiber, such as light resistance, has poor light resistance, poor thermal stability, easy aging, and is not resistant to ironing. However, anti-aging performance can be improved by adding anti-aging agent during spinning.
