Polymerization process: the raw material particles are heated by an extruder to form a solution, and then the metering pump sends the solution to the spinneret as needed;
Spinning process: the solution is formed into fibers through the spinneret;
Stretching process: cooling and solidifying the fiber by the action of secondary air;
Web-forming process: spray the fiber onto the drum or web curtain to condense the web;
Reinforcement process: forming the cloth by thermal bonding or self-adhesion; packaging process: packing the cloth into rolls.
