"Moving-Cavity" Texturing Technology and High-Speed Texturing of Poly(ethylene Terephthalate) Yarns

Abstract

A new "moving-cavity" texturing technology has been developed. The mechanism of texturing consists of yarn striking a moving screen surface to initiate crimp and then being further crimped and "set" in plug form within a cavity. The effects of design and processing conditions to texture poly(ethylene terephthalate) (polyester) yarn (150/ 34) at 2,700 mpm are discussed. The textured yarns have good texture levels and are uniform.
