Premium Black Polyester Yarn for Durable Textiles

    Polyester (Sheath Fiber) Polyester serves as the outer sheath material of the core-spun yarn. It has high tensile strength, excellent abrasion resistance and reliable dimensional stability. It effectively protects the inner spandex core from friction damage during weaving, knitting and dyeing processes. It features good color fastness and anti-pilling performance. Fabrics made from this fiber hold their shape well after repeated washing, and the yarn runs smoothly on textile machines for mass production. Spandex (Core Filament) Spandex forms the elastic inner core of the yarn. It possesses high elongation capacity and outstanding elastic recovery. Wrapped securely inside the polyester sheath, the spandex filament is isolated from direct contact with external friction, which prevents premature aging. The finished fabric maintains consistent elasticity after repeated stretching, offering flexible movement and good shape retention. Summary This core-spun yarn uses polyester as the out…
