UNCRINPABLE TORQUE TEXTURED YARN HAVING Y SHAPE CROSS SECTION AND PRODUCTION THEREOF

摘要

PURPOSE:To obtain the title textured yarn industrially stabilized and improved in quality by subjecting a yarn consisting of a polyamide filament having Y cross section to pin false twist finishing in a specific false twist number and tension ratio. CONSTITUTION:A yarn consisting of one or two polyamide filament having Y shape cross section and 1.75-2.0 deformation degree of cross section is subjected to pin false twist finishing in false twist number of 3200/D<1/2>-5200/D<1/2> (t/m) (b is denier of the above-mentioned yarn) and tension ratio of <=2.0 to provide the aimed textured yarn having 110-260 torque index and suitable in producing a stocking product having excellent transparency and luminous properties.
