Abstract: PROBLEM TO BE SOLVED: To obtain soft combined textured yarn, having a stiff body and a resilient property, rich in heat insulating property and suitable for worsted-like woven fabric by merging thermoplastic synthetic fiber yarns having a temperature difference through a false twisting rotary element for making the combined yarn. SOLUTION: This combined textured yarn having ununiform and short cycled uneven parts and shrinkage differences in the yarn axis direction of its single filaments and showing a gentle wave like crimp, is obtained by unevenly heating any one of the yarns having a lower temperature in its diameter direction as well as its yarn axis direction by the other yarn having a higher temperature in the process of supplying at least 2 yarns selected from a group of stretched yarn, half stretched yarn or unstretched yarn, e.g. stretched yarn A and half stretched yarn B, to the first rollers 1, 2 each independently, false twisting them until the second roller 9 by using hot plates 3, 4 having a temperature difference, a cooling plate 7 and a rotary false twisting element 8 of any of an outer contacting-type friction false twister, a belt nipping-type false twister and a spindle false twister, and winding as a package 12 through an interlacing nozzle 10.

Abstract: PURPOSE:To provide a pile web capable of having rich and various surfaces as well as having improved collectability and excellent shape changes at a low cost by subjecting pile fibers to an alternate twisting treatment instead of the real twisting treatment of the pile fibers. CONSTITUTION:A pile web using pile yarns each comprising two or more constituting fibers is characterized in that each of the pile yarns has an intermittently alternately twisted structure in which S-twisted parts and Z-twisted parts are alternately arranged through non-twisted parts along the longitudinal direction of the pile yarns. A method for producing the pile web of the invention is characterized by tufting the yarns having the intermittently alternately twisted structure as the pile yarns.

Abstract: PURPOSE:To simply, readily and stably obtain textured yarn having homogeneous crimps and high bulkiness by false twist texturing thermoplastic fiber in a low-temperature plasma atmosphere. CONSTITUTION:For example, yarn (Y) of thermoplastic fiber composed of at least one resin selected from polyester-based resins and a polyamide-based resin is treated in a low-temperature plasma atmosphere (e.g. a nonpolymerizable gas plasma) produced with a plasma producer 4 under 0.01-50Torr pressure for >=0.02 sec in at least part of a twisting zone and then cooled with a cooling plate 6. The resultant yarn (Y) is subsequently false twist textured by a false twister (e.g. a fluid or a spindle false twisting method) to afford the objective textured yarn.

Abstract: PURPOSE:To obtain the subject fiber having high strength and excellent dimensional stability under heat and useful as a rubber-reinforcing material such as tire cord or a material for fishing net, sewing thread, tent, rope, etc., by applying a tension to a polyhexamethylene adipamide fiber in a low-temperature plasma atmosphere and drawing the fiber. CONSTITUTION:The objective fiber having high orientation degree corresponding to a birefringence of >=58X10 can be produced by drawing a polyhexamethylene adipamide fiber having a relative viscosity etar of >=3.0, a birefringence of >=30X10 and a density of >=1.128 in a low-temperature plasma atmosphere (preferably an atmosphere of non-polymerizable gas having a pressure of 0.01-50Torr and an applied voltage of 0.5-10KV) at a draw ratio of 1.4-3.5 under a tension of 1.0-5.0g/de.

Abstract: PROBLEM TO BE SOLVED: To provide a process for stably producing a conjugate false-twisted yarn having the feeling of wool and silk, i.e., the springiness, body, resilience and bulkiness and further a spun-like feeling while suppressing the generation of fluffs. SOLUTION: A conjugate false-twisting treatment accompanying a drawing action is carried out by using plural yarns. At least a yarn is wound around the 1st hot roller 5, drawn after the heat-treatment, wound around the 2nd hot roller 8 and heat-treated to obtain a hot yarn A. The hot yarn A and another yarn B having a temperature lower than that of the hot yarn A are twisted with each other by the false-twisting action. In flase-twisting apparatus at least having feed rollers 2a and 2b, the 1st hot roller 5, a joining guide 9 a false-twisting rotor 11 and a take-up roller 12 in the order of the running direction of the yarn, a 2nd hot roller 8 is placed between the 1st hot roller 5 and the joining guide 9.

Abstract: PROBLEM TO BE SOLVED: To produce a knitted or woven fabric hardly causing a fluffy feeling, having body stiffness and high resilience and suitable for an outer garment such as a suit and pants by subjecting plural yarns having temperature difference to a composite false twisting. SOLUTION: At least two yarns A and B with temperature difference imparted by the temperature difference between hot plates 3 and 4 is doubled and subjected to false twisting by a false twisting rotor 8, etc., while heating the yarn B at the lower temperature with the yarn A at the higher temperature to carry out the composite false twisting to provide a composite false twisted yarn having 15-80% shrinkage in boiling water, 1-30% self-elongation, 1-25% crimp recovery, and 1-30% difference of yarn lengths between the yarns A and B. The obtained composite false twisted yarn is subjected to true twisting, and further twist setting at 30-80 deg.C by a dry-heat or a wet-heat, and thereafter knitted or woven to provide the objective knitted or woven fabric, in the method for producing the knitted or woven fabric.

Abstract: PROBLEM TO BE SOLVED: To obtain a composite textured yarn having a wool-like or silk-like feeling and hot causing irregularity such as streaky defect in a state of fabrics. SOLUTION: This composite textured yarn is obtained by giving one yarn A a bundling property with an interlacing nozzle 4 and heating it with a hot plate 5 up to higher temperatures, and by doubling the other yarn B with the yarn A at a lower temperature than that of the yarn A, and then false-twisting them with a spinner such as a false-twisting rotor 7. The yarn B is irregularly heat-treated by the yarn A during a false-twisting process and therefore we can obtain the composite textured yarn having a soft feeling and sufficiently having body, stiffness and resiliency and having excellent uniformity in shape and dimensions.
