FDY is a type of highly drawn polyester filament yarns which can be used to produce high strength fabrics and textiles. We produce both semi-dull FDY and bright FDY. The fabrics and textiles made from bright FDY have a bright luster. FDY is typically used to produce fabrics and textiles for high-end undergarments, high-end sportswear and sports shoes, and home furnishings.
