Process principle of polypropylene short fiber:

Heat and melt the polymer into a spinning melt with a certain viscosity, use a spinning pump to continuously and evenly squeeze it to the spinneret, press it into fine filaments through the spinneret hole, and then cool and solidify it in air or water, and draw it into filaments.

Polypropylene staple fiber process:

Polypropylene staple fibers, direct spinning, and chip spinning.

Direct spinning is the process of transferring polymer melt directly to spinning;

Slice spinning requires the polymer solution to be transported to spinning after being prepared through processes such as tape casting and cutting.

Polypropylene short fibers are a univariate system that only involves heat transfer between polymer melt filaments and cooling media.
