Spun yarn-like textured yarns and process for producing same |
摘要 |
Spun yarn-like textured polyester yarns comprised of two types of polyester multifilament component yarns and having broken filaments, in which textured yarns there is a difference in length between the component yarns, whereby high bulkiness is imparted thereto. The individual filaments of one of the component yarns have a fineness less than those of the other component yarn. The spun yarn-like textured yarns have satisfactory pilling resistance and frosting resistance. The spun yarn-like high bulky textured yarns can be produced by a process comprising doubling two types of undrawn polyester multifilament yarns having different properties through an intertwisting regulative device and simultaneously draw-texturing the doubled undrawn yarns.
