Understand 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 squeezed to the spinneret by a spinning pump, and then pressed into fine filaments flowing through the spinneret holes, and then cooled and solidified in air or water, and then produced by drawing.

Polypropylene staple fiber technology mainly includes:

Preparation of spinning melt; The melt is pressed out through the holes in the spinneret -- forming a melt flow; The melt flows, elongates, tapers, cools and solidifies. Oiling and winding of solid wire.

The main characteristics of polypropylene staple fiber:

Fast winding speed, no need for solvent and precipitating agent, simple equipment, short process time. Using this method, fiber polymers can be prepared with melting point lower than decomposition temperature and can be melted to form heat stable melt. Such as polyester, polypropylene, nylon, etc.
