Definition and application of polypropylene staple fiber: The polymer is heated and melted into a spinning melt of a certain viscosity, and is continuously and evenly extruded to the spinneret by a spinning pump, and is pressed into filaments through the spinneret holes, and then cooled and solidified in air or water, and drawn into filaments.

The polypropylene staple fiber process mainly includes: preparation of spinning melt; the melt is pressed out through the holes of the spinneret - forming melt flow; the melt flow is elongated, thinned, cooled and solidified. Oiling and winding of solid wire.

Uses of polypropylene staple fiber: sanitary non-woven fabrics, needle-punched carpets, needle-punched non-woven fabrics, automotive interior fabrics, geotextiles, filter cloths, clothing linings, filter yarns, electric blankets and other fields, and can also be blended with cotton and man-made fibers.

Polypropylene staple fiber, with its unique texture, occupies an important position in the field of synthetic fibers. First of all, it has an extremely light weight, with a relative density of only 0.91g/cm3, which is a variety with a lower density among common chemical fibers. This characteristic makes polypropylene staple fiber much lighter than other fibers when covering the same area.

Our customers use polypropylene staple fiber in different products and markets. Each market and application has different requirements for the characteristics of polypropylene. We are not just a simple supplier. We can develop and customize corresponding polypropylene staple fiber products for customers based on the specific needs of customers or projects, from raw material ratios, product characteristics to production processes.
