The characteristics of polypropylene Staple  fiber: polypropylene short fiber density is small, light, can float on the water; Polypropylene colored yarn has high strength and strong tensile resistance. Polypropylene staple fiber has a certain acid and alkali corrosion resistance, even if immersed in seawater are not to worry about; The hygroscopicity of polypropylene staple fiber is small, almost no hygroscopicity; polypropylene Staple fiber is environmental protection and pollution-free products.

Introduction of physical and chemical properties of polypropylene Staple  fiber

1, the longitudinal surface of the shape of polypropylene is straight and smooth, and the cross section is circular.

2, the advantage of density polypropylene is light texture, its density is only 0.91g/cm3 is the most common chemical fiber density of the lightest variety, so the same weight of polypropylene than other fibers to get a higher coverage area.

3. High tensile polypropylene has high strength, large elongation, high initial modulus and excellent elasticity. So polypropylene wear well. In addition, the wet strength of polypropylene is almost equal to the dry strength, so it is an ideal material for making fishing nets and cables.

4, moisture absorption and dyeing light and good heat preservation; Almost no moisture absorption, but the heart suction ability is very strong, moisture absorption and sweating effect is obvious; Polypropylene hygroscopicity is very small, almost no hygroscopicity, the moisture return rate under general atmospheric conditions is close to zero. But it has a core action, can transfer water vapor through the capillary in the fabric, but does not absorb any of its own. The color of polypropylene staple fiber is poor and the chromatogram is incomplete, but the method of stock solution coloring can be used to make up for the deficiency.

5, acid and alkaline resistance polypropylene has good chemical corrosion resistance, in addition to concentrated nitric acid, concentrated caustic soda, polypropylene acid and alkali resistance is good, so suitable for use as filtration materials and packaging materials.

6. The strength of high strength polypropylene elastic wire is second only to nylon, but the price is only 1/3 of nylon; Made of fabric size stability, wear-resisting elasticity is also good, good chemical stability. But poor thermal stability, not resistant to sunlight, easy to aging brittle damage, so often in polypropylene added anti-aging agent.
