Polypropylene staple fiber is a kind of non-absorbent or very low water absorption, and cannot be dyed like other synthetic fibers such as polyester, eyeglass, etc., and because of its high static electricity, it is difficult to perform processing such as cleaning and spinning. Limiting its application, high-efficiency, durable, practical antistatic agent, dyeable components were analyzed and screened

Polypropylene staple fiber can well improve the crack resistance, impermeability, erosion resistance, frost resistance, explosion resistance of mortar/concrete and improve the workability of concrete. Tens of millions of fibers are evenly distributed in the mortar/concrete, which plays a good role of micro-reinforcement, so that the integrity of the structure is well maintained, and the structure is prevented from being scattered into many fragments when the structure is impacted. The corrosion of the steel bars can greatly extend the service life of the project and reduce the maintenance cost of the project. White recycled flame-retardant polyester staple fiber.
