The polypropylene staple fiber is the synthetic fiber which is spun by the isotropic polypropylene obtained by the propylene polymerization. The commodity name is polypropylene.

Polypropylene staple fiber is spun by solution. Almost no moisture absorption, but with a unique core, water vapor can be transported through capillary tubes. Therefore, it can be made into sportswear or press cloth. Poor staining and incomplete chromatographic staining.

Polypropylene staple fiber has the advantages of high strength, good toughness, good chemical resistance and microbial resistance and low price, so it is widely used in rope, fishing net, safety belt, luggage belt, safety net, sewing thread, cable cover, geotextile, filter cloth, paper felt and paper reinforcement material industry fields.

Thepolypropylene staple fiber made of high strength, acid resistance, alkali resistance, microbial resistance, dry and wet strength and other excellent characteristics can strengthen the civil engineering built on the soft soil foundation (such as DAMS, reservoirs, highways, railways, etc.), and make the load evenly distributed on the geotextile, so that the subgrade settlement is uniform, reduce the ground cracking.

When building the slope, using woven polypropylene short fiber geotextile can stabilize the slope, reduce the slope collapse, shorten the construction period, extend the service life of the slope. When the load is larger, the composite geotextile based on PP staple fiber woven geotextile and nonwoven geotextile can be used.

Of course, polypropylene staple fiber can be used as a filling material for concrete, mortar, etc., to improve the impact resistance of concrete, waterproof and heat insulation.
