How To Match Spandex Double-covered Yarn Models Under Different Process Requirements?

The key to selecting spandex double-covered yarn lies in matching the elasticity requirements of the actual processing technology. Warp knitting typically requires yarns with higher resilience and uniformity, while weft knitting focuses more on the softness and coverage of the yarn.

Warp knitting yarn: Prioritize yarns with higher coverage and uniform twist to ensure stable elasticity release during high-speed knitting.

Weft knitting yarn: Emphasize yarn surface smoothness to prevent spandex fibers from being exposed due to friction, which would affect the feel of the finished product.

Special pattern knitting: Requires special twist directions or double-ply structures to prevent fabric twisting and deformation.

Cotton-spandex core-spun yarn, with its naturally skin-friendly outer cotton fiber, is more suitable for knitted underwear, socks, and other products that come into direct contact with the skin. Its combed version further enhances yarn strength, making it suitable for cuffs and necklines that require frequent stretching.

High-elasticity double-covered yarn, with its double-layer spandex fiber coverage structure, provides stronger resilience than conventional core-spun yarn and is often used in sportswear, shapewear, and other applications with stringent requirements for deformation recovery. However, it should be noted that its high rigidity may affect the drape of some ultra-thin fabrics.
