Do you know wet spinning?

A method in which a dope is solidified into filaments by double diffusion in a coagulation bath.

Production process: stock solution----spinning pump----enter warm water from spinneret, below 90℃----regeneration tank coagulation bath----remove solvent----

filament washing--- -Drying----winding and forming.

Spinning speed: from 50 to 150M/min.

Spinning temperature: warm water below 90°C.

Fiber fineness: 44～440dtex.

Features: The production process of this method has large pollution, slow spinning speed and high cost.
