Polypropylene woven geotextiles made of polypropylene staple fibers with high strength, acid resistance, alkali resistance, anti-microbial, dry and wet strength and other excellent characteristics can be used for civil engineering (such as dams, reservoirs, highways, etc.) built on soft soil foundations. Railway, etc.) play a reinforcing role, and make the bearing load evenly distributed on the geotextile, so that the subgrade settlement is even, and the ground cracks are reduced.

When building a slope, the use of woven  polypropylene staple fiber geotextile can stabilize the slope, reduce the collapse of the slope, shorten the construction period and prolong the service life of the slope. When carrying large loads, PP short fiber woven geotextiles and non-woven fabrics can be used as composite geotextiles.

Of course, polypropylene staple fibers can be used as filling materials for concrete, plaster, etc., to improve the impact resistance, waterproof and heat insulation of concrete.

Polypropylene staple fiber is a synthetic fiber spun from isotactic polypropylene obtained by propylene polymerization as a raw material, and its trade name in my country is polypropylene.

Polypropylene staple fiber has the advantages of high strength, good toughness, good chemical resistance and anti-microbial resistance and low price, so it is widely used in ropes, fishing nets, safety belts, luggage belts, safety nets, sewing threads, cable sheathing, geotextiles , filter cloth, papermaking felt and paper reinforcement materials and other industrial fields.

Taizhou Hailun Chemical Fiber Co., Ltd., formerly known as Taizhou Chenguang Synthetic Fiber Factory, was founded in 1995.
