What are the excellent characteristics of PP staple fiber?

PP staple fiber is a synthetic fiber spun from isotactic polypropylene obtained from propylene polymerization, and the product name is polypropylene in China.

PP 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 nets, safety belts, luggage belts, safety nets, sewing thread, cable cover, geotextiles, filter cloth, paper felt and paper reinforcement materials and other industries.

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

When building the slope, the use of woven PP short fiber geotextiles can stabilize the slope, reduce the collapse of the slope, shorten the construction period and extend the service life of the slope. When carrying large loads, composite geotextiles based on PP staple fiber woven geotextiles and nonwovens can be used.

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