Abstract: PROBLEM TO BE SOLVED: To produce a composite processed yarn in which slub-like entangled portions and substantially non-twisted entangled portions are alternately repeated in the longitudinal direction of the yarn in irregular lengths, and which has a spun-like touch, a projection-like hand touch, and deep black color surface variation, when dyed with a black dye, and is suitable for the use of black formal wears, and to provide a method for producing the same. SOLUTION: This composite processed yarn in which slub-like entangled portions and substantially non-twisted entangled portions that comprise a cation dye-dyeable filament yarn as a sheath yarn are alternately repeatedly formed on a core yarn comprising polyethylene terephthalate filaments in the longitudinal direction of the yarn in irregular lengths is characterized in that the colors of the slub-like entangled portions are deeper than the colors of the substantially non-twisted entangled portions, when dyed with a black dye.

Abstract: PROBLEM TO BE SOLVED: To provide a composite false-twisted yarn which has an irregular multicolor splashed pattern effect and an uneven touch at arbitrary positions in the longitudinal direction of the yarn, and has a natural spun yarn-like touch. SOLUTION: This composite false-twisted yarn is obtained by interlacing the thick-and-thin false twisted yarn A of ionic dye-dyeable fibers with the thick-and-thin false twisted yarn B of non-ionic dye-dyeable fibers. Therein, after subjected to repeated tension-relaxation treatments, the false-twisted yarn has the irregularly repeated lengths of the opened portions in the interlaced yarn form of interlaced portion-opened portion-interlaced portion in the longitudinal direction of the yarn. The practical yarn lengths of the thick-and-thin false twisted yarns contained in a constant length of the composite false-twisted yarn are expressed by (the false twisted yarn A

Abstract: PROBLEM TO BE SOLVED: To obtain a textile having knit-toned appearance and excellent in knit-toned surface uneven effect and dry touch. SOLUTION: This textile comprises false twist coil stretch yarn consisting of 100-500 denier thermoplastic synthetic multifilament yarn as the warp A and/or weft B. The warp A and/or weft B have coil parts having same twisting phase of false twisting and straight parts, 2-100 average coil number n per one inch, real twist in false twist direction and organizing points, that is, inclined interlacing points θ of the warp A with the weft B.

Abstract: PURPOSE:To obtain an elastic fiber having excellent heat-stability and flexural fatigue resistance, by melt-spinning a polymer composed of specific aliphatic diamine, aliphatic dicarboxylic acid, poly(alkylene oxide) glycol, etc., and a dicarboxylic acid and drawing the fiber at a specific draw ratio. CONSTITUTION:The objective fiber can be produced by melt-spinning a polyether ester amide polymer and/or polyether amide polymer derived from (A) a 6-20C aliphatic diamine, (B) a 6-15C aliphatic dicarboxylic acid (equimolar amount to the component A), (C) a poly(alkylene oxide) glycol and/or poly(alkylene oxide) diamine having a number-average molecular weight of 300-6,000 and (D) a 4-20C dicarboxylic acid, cooling and solidifying the spun fiber and drawing the fiber successively or continuously at a draw ratio larger than 0.5 times the breaking elongation of the elastic fiber.

Abstract: PURPOSE:To improve cooling effect while keeping a reduced pressure state, by setting a cooling air sending part at just below a spinneret in a spinning column in a reduced pressure atmosphere, withdrawing cooled yarn from an outlet part of the fluidly sealed spinning column by a withdrawing means laid at the outside of the spinning column. CONSTITUTION:The movable column 17 is brought into contact with the ring- shaped chimney 12 by pressure, and the space Sa extending from a position just below the spinneret 7 to the seal guide 24 at the bottom of the fixed cylinder 18 is prepared. Degree of reduced pressure of the space Sa is detected by the vacuum meter 27, and the vacuum pump 26 is regulated by the controller 22 to make the degree of reduced pressure constant. The yarn Y is cooled and solidified by cooling air sent from the chimney.

Abstract: PROBLEM TO BE SOLVED: To obtain a coated elastic yarn having excellent coatability, stretch power, elastic recovery ratio, soft feeling, dyeability, or the like, and to provide a method for producing the same. SOLUTION: The coated elastic yarn comprises an elastic yarn as a core yarn and a false-twist crimpled yarn as a sheath yarn, composed of a conjugate fiber made of a polytrimethylene terephthalate as at least one component in which the elastic yarn of the core yarn is coated with the sheath yarn of the false-twist crimpled yarn composed of the conjugate fiber substantially by false twisting.
