Abstract

Air-jet textured core/effect nylon yarn provides fabrics having better cover when the core component has been draw-oriented after conventional melt-spinning, and the effect component has been spin-oriented by melt-spinning at unusually high speed. The improved yarn is particularly useful in upholstery fabrics.
