Do you know melt spinning?

a method in which the polymer is heated to above the melting point to become a melt and become a filament.

Production process: Polymerization without solvent----Pelletizing----Slicing at constant temperature----Cleaning and removing impurities----Drying----Dehydration----Entering screw press Made into a solution - spinneret extrusion - cooling through a cold box - winding molding.

Spinning speed: from 600 to 1600M/min.

Spinning temperature: 160～220℃.

Fiber fineness: 9～1100dtex.

Features: short process, low cost, low pollution.
