Polypropylene staple fiber as an important member of the synthetic fiber family, has shown extraordinary application potential in multiple fields with its unique physical and chemical properties.Its most notable feature lies in its extremely low density, only 0.91g/cm, which is much lower than that of other common synthetic fibers. This makes the products made from it not only lightweight but also have good thermal insulation and hydrophobicity. This feature has been widely applied in outdoor clothing, thermal insulation materials and hygiene products, effectively enhancing the comfort and functionality of the products.


In terms of mechanical properties, Polypropylene staple fibers demonstrate a perfect combination of high strength and high elasticity. It has high breaking strength, large elongation, and its wet strength is basically the same as its dry strength. This characteristic makes it perform well in the production of products such as ropes, fishing nets, and safety belts that need to withstand high-intensity tensile forces. Meanwhile, its excellent wear resistance and chemical corrosion resistance have further expanded its application scope in industrial filter cloth, geotextile and other fields, providing reliable material support for infrastructure construction.


With the advancement of technology, the modification technology of Polypropylene staple fibers has been constantly broken through, promoting the continuous expansion of its application fields. Through blending modification, graft copolymerization and other means, fibers can be endowed with multiple functions such as antibacterial, flame-retardant and UV resistance, meeting the demands of high-end markets such as medical care, protection and outdoor equipment. Especially in the field of hygiene materials, hot-melt Polypropylene staple fibers, with their low strength and high elongation properties as well as excellent water permeability, have become the ideal choice for the production of nonwoven hygiene materials such as sanitary napkins and diapers. In addition, polypropylene short fibers also demonstrate great potential in the field of environmental protection. Their recyclability and biodegradability provide new ideas for solving the problem of plastic pollution.
