Polyester filament is a synthetic fiber material made from polyester (PET) through a melt spinning process, belonging to a form of polyester (polyethylene terephthalate).
Its production process includes polymerization, melting, spinning, stretching, and winding steps, ultimately forming a continuous filament structure. Polyester filament features high strength, abrasion resistance, corrosion resistance, UV resistance, and low moisture absorption, and is easy to dye and process.
