Polyester in Apparel: Sportswear and Fashion
topic
Apparel polyester applications: (1) Sportswear/activewear: moisture-wicking DTY knits, high-stretch PET/elastane wovens, compression fabrics (FDY warp-knit, 75D/144F); (2) Outwear/fleece: open-end spun rPET staple fleece (Polartec®), bonded fleece (thermal bonding of fibre web); (3) Fashion/woven: FDY and DTY weaving yarns, peach-skin finishing (emery abrasion of microfibre fabric); (4) Linings: 100% polyester taffeta (low friction, light, dimensionally stable); (5) School uniforms/workwear: PET/cotton blends (65/35) — durability + comfort. Global apparel polyester consumption: ~34 million tonnes/year.
Role
Apparel is the dominant application domain for polyester, encompassing the widest range of yarn types, fabric constructions, and finish technologies. Understanding each sub-segment's specific requirements illustrates applied fibre selection and product development logic.
