wet spinning
WET-SPINNING, a method in which the original solution is solidified into silk 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.
chemical reaction
A method in which a polymer is made into a solution by chemical reaction with a chain extender, and then solidified into a silk.
Production process: solution - through spinneret to coagulation liquid - adding chain extender - winding forming - hardening - processing into mesh fibers.
Spinning speed: from 50 to 150M/min.
Fiber fineness: 44～80dtex.
Features: This method has large pollution and high cost in the production process.
