Abstract: PURPOSE:To obtain a yarn of mixed filaments differing in deniers comprising a fine- denier dividable segment and a high-denier segment with a different cross section and giving woven and knitted fabrics which have high softness, bulkiness and rich drapeability. CONSTITUTION:(A) Polyethylene terephthalate(PET) containing 1.2 to 10wt.% of titanium oxide dull additive is prepared as the polymer 1 for the segment to be divided 1, and (B) a hot water-soluble isophthalic acid-copolymerized PET as a dividable segment 2 and as a taperable segments 3 and (C) an isophthalic acid-copolymerized PET containing 1.2 to 10wt.% titanium oxide dull additive as a highly different cross section segment 4 are also prepared. Both the low-shrinkage dividable conjugated filaments comprising the polymer components 1 and 2 with the denier of the divided segment of 0.05 to 0.5de and the conjugated filaments whose single yarn deniers are 4 to 10 comprising polymer components 3 and 4 are simultaneously melt-extruded through a same spinneret to give the yarn of mixed filaments differing in deniers. The mixed filament yarn is used as weft and warp to form a woven fabric, then treated with hot water to leach out the components 2, 3 and obtain a woven fabric in which the count of the denier of the fine filaments is more than 20 to that of the thick filaments.

Abstract: PURPOSE:To obtain napped woven and knitted fabrics having excellent gloss and deepness in color and a high-class feeling by using ground yarn composed of polyester yarn and pile yarn having a specific dulling agent content and fineness, respectively, wherein yarn having a product of strength and elongation in a prescribed range is used as the pile yarn. CONSTITUTION:Polyester yarn having 1.0-4.0de fineness of single yarn is used for ground yarn and pile yarn. Yarn containing 0.05-0.5wt.% of a dulling agent such as titanium oxide, having 50-100de fineness is used as the ground yarn and yarn containing 0-0.1wt.% of a dulling agent, 75-125de fineness and 3.5-6.5 product of strength and elongation when the product of strength and elongation=TX(1+E/100) [in the formula, T is strength (g/d) at break, E is elongation (R) at break] is used as the pile yarn. Woven and knitted fabrics of double structure are produced by using the ground yarn and the pile yarn, subjected to center cutting and passed through a shearing process to give napped woven and knitted fabrics having stable qualities with slight wear of a knife without deforming the cut section.

Abstract: PURPOSE:To stably produce the subject fiber having high quality by specifying the roughness of the inner wall of the pipe for introducing electrically conductive polymer, the roughness of the wall of the nozzle hole and the tapering angle between the polymer-introducing part and the extrusion part, filling a non-conductive polymer and then switching to an electrically conductive polymer. CONSTITUTION:An electrically conductive fiber is produced by the composite spinning of an electrically conductive polymer containing 15-20wt.% of electrically conductive carbon black and a fiber-forming non-conductive polymer. The composite spinning spinneret 1 to be used in this process is composed of an electrically conductive polymer introducing hole 1, an electrically conductive polymer metering and restricting hole 3, a non-conductive polymer introducing hole 2, a nonconductive polymer metering and restricting hole 4, a composite polymer introducing hole 5 and a composite extrusion hole 6. The roughness of the inner wall of the polymer pipe for passing the electrically conductive polymer is set to

Abstract: PURPOSE:To obtain polyester hollow fiber having collapse resistance, light weight and heat retaining properties as well as excellent transparency which no conventional material can attain and unique color-developing properties, thus giving a valuable excellent fiber material which can be distinguished from conventional ones. CONSTITUTION:The hollow fiber has a round cross section, a triangular hollow cross section and 10 to 15% hollowness, thus showing high collapse resistance. No conventional hollow fibers could have reached the high level of collapse resistance and the fiber can be used as a material for knitted wear, especially sport wear manifesting full effect of the high collapse resistance.
