Product Description
The production process of polyester yarn mainly includes four stages: Raw Material Preparation → Spinning → Yarn Formation → Post-treatment.
Polyethylene terephthalate (PET) melt is produced by esterification and polycondensation reactions of terephthalic acid (PTA) and ethylene glycol (EG).
The melt is extruded through spinnerets, then cooled and solidified into polyester filaments or staple fibers (staple fibers are cut to cotton-type or wool-type lengths).
This stage includes heat setting (to improve dimensional stability), dyeing (to impart color as required), and winding (to form finished yarn packages).
