Qinfeng Chemical Fiber is a company focusing on the production, research and development, sales of polypropylene staple fiber and polyester staple fiber, located in Hai 'an County, Nantong City, after years of development, the company with professional technical strength, front-end quality testing system and perfect quality testing system ranks among the industry's high-quality enterprises, in order to advance to the high-end, expand the market, our company with a lofty attitude, Committed to the independent research and development of polypropylene staple fiber, PP staple fiber, polyester staple fiber and other products, innovation as a benchmark, to establish a model of industry forward.

Our main products are polypropylene staple fiber and polyester staple fiber.

Polypropylene staple fiber density is small, light, can float on the water; High strength of polypropylene yarn, strong tensile resistance; Polypropylene staple fiber has a certain acid, alkali and corrosion resistance, even if soaked in seawater inside do not have to worry; Polypropylene short fiber hygroscopicity is small, almost not hygroscopicity; Polypropylene staple fiber is environmental protection and pollution-free products.

Introduction to physical and chemical properties of polypropylene staple fibers

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

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

3, strong extension polypropylene fiber has high strength, large elongation, high initial modulus and excellent elasticity. So polypropylene has good wear resistance. 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 quality good heat preservation; Almost not hygroscopic, but the heart absorption ability is very strong, hygroscopic sweating effect is obvious; The hygroscopic property of polypropylene fiber is very small, almost no hygroscopic, general atmospheric conditions under the moisture recovery rate is close to zero. But it has a core absorption effect, which can transfer water vapor through the capillary tubes in the fabric, but does not have any absorption effect on itself. The dyeing property of polypropylene short fiber is poor and the chromatography is not complete, 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 corrosion resistance, in addition to concentrated nitric acid, concentrated caustic soda, polypropylene acid and alkali resistance is good, so suitable for filtration materials and packaging materials.

6, high strength polypropylene filament strength is second only to nylon, but the price is only 1/3 of nylon; The fabric is stable in size, good in wear resistance and elasticity, and good in chemical stability. But the thermal stability is poor, not fast, easy to aging brittle damage, so often add anti-aging agent in polypropylene fiber
