Polypropylene staple fiber is a kind of fiber material made from polypropylene as raw material through processes such as melting, drawing, spinning and cutting. During the production process, functional masterbatches such as anti-aging masterbatches and flame-retardant masterbatches can be added according to actual needs, thereby endowing it with more outstanding performance. Among them, polypropylene staple fiber for felt is a category specifically used for making felt and has important applications in the field of filter materials.

From the perspective of classification, polypropylene staple fibers, referring to the specifications of natural fibers, can be divided into cotton type, wool type, carpet type and medium-long type, etc. Its textile methods are flexible and diverse. It can be spun alone or blended with natural fibers or other fibers in different proportions to produce various products such as yarns, fabrics and felts.

The performance advantages of polypropylene staple fibers are very prominent. It has excellent moisture conductivity and flexibility, and performs well in web formation, carding and heat bonding. Meanwhile, it features high strength, strong curling elasticity, light weight, low melting point and good surface permeability. Its acid and alkali resistance and wear resistance are even superior to many other fibers.

With these excellent properties, the application fields of polypropylene staple fibers are extremely wide, covering needle-punched non-woven fabrics, hygiene non-woven fabrics, needle-punched carpets, automotive interior fabrics, geotextiles, speaker fabrics, filter fabrics, filter yarns, garment interlinings, artificial fur, spinning, spinning yarn, filter materials and adsorption materials, and many other fields, playing an important role in various industries.
