Seven characteristics of PP fibre!

1. The vertical surface of the form polypropylene is flat and smooth, and the cross-section is circular.

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

3, strong extensional polypropylene has high strength, large elongation, high initial modulus and excellent elasticity. So polypropylene wear resistance is good. In addition, the wet strength of polypropylene is basically equal to the dry strength, so it is the ideal material for making fishing nets and cables.

4, PP fibre moisture absorption and dyeing, light quality and good heat preservation; Almost no moisture absorption, but the core absorption ability is very strong, moisture absorption and sweating effect is obvious; The hygroscopic property of polypropylene is very small, almost non-hygroscopic, and the moisture regain rate under general atmospheric conditions is close to zero. However, it has a core suction effect, which can transfer water vapor through the capillary tubes in the fabric, but does not have any absorption effect itself. The dyeing property of polypropylene is poor and the chromatography is incomplete, but the method of stock solution coloring can be used to make up for the deficiency.

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

6, PP fibre light resistance and other polypropylene light resistance is poor, thermal stability is also poor, easy to age, not resistant to ironing. However, the anti-aging properties can be improved by adding anti-aging agents during spinning. In addition, the electrical insulation of polypropylene is good, but it is easy to produce static electricity during processing. Because the thermal conductivity of polypropylene is small, the heat preservation property is good.

7, high strength polypropylene filament strength is second only to nylon, but the price is only 1/3 of nylon; The size of the fabric is stable, the wear resistance and elasticity are good, and the chemical stability is good. However, the thermal stability is poor, not resistant to sunlight, easy to aging brittle damage, for which anti-aging agents are often added to polypropylene.

Shandong Huimin Taili Chemical Fiber Products Co., Ltd. was founded in 2017, the company now has the domestic advanced fiber production line, twisting production line. Anti-aging, acid and alkali resistance, low boiling water shrinkage, high breaking strength, low elongation, environmental protection and pollution-free. Widely used in chemical fiber rope net, fire hose, sling, safety belt, concrete, mortar, engineering fiber, etc., is to replace polyester, nylon, ethylene fiber, nylon, glass fiber new ideal material.
