Abstract: PROBLEM TO BE SOLVED: To provide a process for producing a textured conjugate yarn giving a woven or knit fabric having soft texture and high springiness, stiffness and resiliency, exhibiting deep natural color tone and giving comfortable soft feeling to the wearing person. SOLUTION: Conjugate false-twisting work is carried out by using at least three yarns. The plural yarns are divided into two groups, i.e., the fiber group A and the fiber group B, these groups are supplied to feed rollers 2a, 2b at the same or different speeds and at least one group A is heat-treated with a heater. Both groups are joined together in a state having temperature difference by the twisting action of a false-twisting rotor to obtain the objective textured conjugate yarn.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing at low cost textured yarn enabling spun-rich feeling like that of silk spun yarn to be presented through developing natural feeling-rich puffiness and gentle crimps when made into a woven/knit fabric by affording length difference and/or shrinkage difference among constituent filaments and also affording at least part of the filaments with crimps. SOLUTION: This texturized yarn is obtained by the method comprising the following process: a feed multifilament is brought for a short time into contact with the surface of a hot roller in revolution substantially at the same rate as a feed roller so as to develop heating unevenness among the constituent filaments to afford them with length difference and/or shrinkage difference followed by affording the resultant multifilament with false twists by the action of a turning nozzle to afford at least part of the filaments with crimps.

Abstract: PROBLEM TO BE SOLVED: To obtain a polyester differently shrinkable combined filament yarn having difference in shrinkage in the fiber axis direction in any constitutent single yarn and sufficient difference in shrinkage between constitutent single yarns at an arbitrary point in the fiber axis direction so as to develop a more natural swelling in a woven or knitted fabric. SOLUTION: This polyester differently shrinkable combined filament yarn is characterized in that a degree of crystallization and an optical birefringence change in a fiber axis direction in any constitutent single yarn, a degree of crystallization and an optical birefringence have distributions between constitutent single yarns at any arbitrary point in the fiber axis direction, when a primary regression curve of the distribution is obtained by a method of least squares in a single yarn group having a higher degree of crystallization in the distributions, the inclination m is m>0 and the optical birefringence is continuously distributed.

Abstract: PROBLEM TO BE SOLVED: To obtain a knitted and deknitted yarn capable of providing a fabric having a soft surface touch, proper stretchability and drapability and yet excellent surface quality. SOLUTION: This knitted and deknitted yarn capable of providing the fabric having a soft surface touch, proper stretchability and drapability and yet excellent surface quality is obtained by knitting a yarn composed of a polypropylene terephthalate, heat-setting the knitted fabric and then deknitting the knitted fabric.

Abstract: PROBLEM TO BE SOLVED: To obtain a bulky yarn generating a puff rich in natural feeling on making a woven or knitted fabric from it, and capable of expressing a coreless touch feeling by making a fed multi-filament in contact with the surface of a hot roller under a specific condition and imparting the fiber length difference among its single filaments. SOLUTION: This bulky yarn is obtained by bringing a fed multi-filament having >=6 constituting single filaments in contact with the surface of a hot roller 3 having Tg+20-Tm deg.C (Tg is a glass transition temperature; Tm is a melting point) surface temperature and rotating essentially at a same speed with a feeding roller 2 for 5×10-4-5×10-2 sec so as to generate heating unevenness among the single fibers to impart the fiber length difference and/or shrinkage difference among the constituting single fibers. Further, it is preferable that the fed multi-filament is of a polyethylene terephthalate, and the yarn tension in feeding the yarn to the hot roller 3 is 5×10-3 CN/dtex.

Abstract: PROBLEM TO BE SOLVED: To provide a water purifier and a water-purifying system capable of suppressing the propagation of bacteria in water stayed in the purifier over a long period and manufacturing highly safe drinking water. SOLUTION: This tube structure comprises a molded body containing an antibacterial agent in a tube. The tube forming the tube structure is formed of a high polymer material. The molded body containing the antibacterial agent is molded without being molded integrally with the tube. The water purifier and the water-purifying method use the tube structure.

Abstract: PROBLEM TO BE SOLVED: To provide a knitted or woven fabric having excellent tension, stiffness and repulsion, having a dry touch, and further having a natural irregular touch similar to that of a grandrelle yarn after dyed. SOLUTION: The objective composite polyester false-twisted yarn comprises at least two kinds of false-twisted and crimped polyester multi-filaments A and B, wherein the multi-filaments B have a large shrinkage degree than that of the multi-filaments A and contain single filaments partially having undrawn portions. The composite polyester false-twisted yarn comprises at least two kinds of false-twisted and crimped polyester multi-filaments A and B, wherein the multi-filaments A have a smaller shrinkage degree than that of the multi- filaments B and contain single filaments partially having undrawn portions. The method for producing the composite polyester false-twisted yarn comprises combining and falsely twisting plural filaments containing at least one thick and thin filament. Therein, the filaments having a higher temperature are joined to the filaments having a lower temperature by the twisting action of a rotary false-twister, and the filaments having the lower temperature are heated with the filaments having the higher temperature.

Abstract: PROBLEM TO BE SOLVED: To provide a method for stably producing a bulky yarn capable of exhibiting fullness rich in a natural feeling and a touch feeling without a core when the yarn is formed into a woven or a knitted fabric by imparting a difference in filament length or/and a difference in shrinkage among constituent filaments and further changing the shrinkage percentage in the fiber axial direction. SOLUTION: Feed rollers, a turning nozzle, a hot roller and takeoff rollers are installed in the order mentioned in the yarn running direction and a feed multifilamant yarn in a state thereof false twisted with the turning nozzle is brought into contact with the surface of the hot roller rotating at the substantially same speed as that of the feed rollers in a short time so as to produce unevenness of heating among the constituent filament. Thereby, the difference in filament length or the difference in shrinkage or both are imparted among the constituent filaments.
