Learn about the principle of polypropylene staple fiber  process!

The polymer is heated and fused into a spinning melt of a certain viscosity, which is continuously and evenly extruded to the spinneret by the spinning pump, pressed into a filament flow through the spinneret hole, and then cooled and solidified in air or water, and formed into a filament by drafting.

Polypropylene staple fiber process mainly includes:

The production process of polypropylene staple fiber is a precise and complex process, which mainly involves multiple steps such as raw material preparation, melt spinning, drafting, crimping, drying and shaping, cutting and packing.

Polypropylene staple fiber selection of high quality polypropylene resin as the main raw material. According to product requirements, functional masterbatches may be added, such as anti-aging masterbatches, flame retardant masterbatches, etc., to enhance the special properties of the fiber. Polypropylene resin is heated to a molten state, continuously and evenly extruded to the spinneret through a spinning pump to form a filament flow, and then cooled in air or water to solidify. After cooling, the filaments undergo a drafting process to improve the strength and elasticity of the fibers. By mechanical action, the fiber forms a curly structure to increase its fluffiness and softness.
