Abstract: PROBLEM TO BE SOLVED: To provide a water absorbing material from which moisture does not leak or ooze and consequently does not cause a person to feel damp, causes the person to feel excellent comfortableness when worn and can be used repeatedly by washing. SOLUTION: This fabric-like water absorbing material is obtained by using a split type conjugate fiber which consists of at least two components, namely, a polycapramide polymer as component A and a polyester polymer as component B and which can be split into extra fine fibers of 0.01 to 3 dtex single yarn fineness and incorporating an antibacterial agent in the conjugate fiber or sticking the antibacterial agent to the surface of the conjugate fiber. The porosity of this water absorbing material is made to be ≥10 cc per 100 cm 2 and the thickness is made to be 0.5 to 20 mm. COPYRIGHT: (C)2004,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a raised cloth having improved spinnability while keeping the multicolor property. SOLUTION: The raised cloth is produced by using a raising yarn consisting of a spun yarn obtained from a core-sheath conjugate staple fiber composed of sheath component comprising a copolyester containing ethylene terephthalate as a main repeating unit and copolymerized with a component containing a metal sulfonate group and a core component comprising a polyethylene terephthalate and a polyester staple fiber having a dyeability different from that of the core-sheath conjugate staple fiber.

Abstract: PURPOSE:To obtain the high-quality polyamide tow with animal hair-like touch, having good stretch breaking nature by melt spinning of nylon 66 dope followed by cooling and solidification and then oiling the resultant fibers with a lubricant containing both surfactant and inert fine particles so as to result in a specified amount of the inert fine particles attached to the fibers. CONSTITUTION:Nylon 66 dope containing 0.25wt.% of titanium dioxide is put to melt spinning through a spinneret heated to 285 deg.C and taken up at a speed of 1200m/min to form an undrawn subtow. A plural number of such subtows are then put in parallel into an undrawn tow, which is, in turn, put through a bath where a lubricant containing a surfactant (e.g. lauryl alcohol-based phosphoric ester potassium salt) and inert fine particles (e.g. silica) is placed, to provide oiling treatment. Thence, the resulting tow is put in between a pair of rubber nip rollers to control the pickup of the inert fine particles on the fibers so as to come to 0.1-1.0wt.% based on the fibers. Thence, the tows are drawn in steam by a factor of 3.5 and heat treated on a drum at 170 deg.C and then crimped, thus obtaining the objective polyamide tow

Abstract: PROBLEM TO BE SOLVED: To provide a drawing method for synthetic staple effective for reducing emergency stop relating to entanglements by installing a guide having a specific shape. SOLUTION: In a production process for synthetic staple drawing and heat treating after melt spinning a thermoplastic polymer, a ctenoid shaped guide 4 is installed before guiding the undrawn fiber to the drawing process and tearing off the entanglements by this ctenoid shaped guide 4 before entering to the drawing machine.

Abstract: PURPOSE:To obtain the polyamide tow capable of stretch-breaking spinning in a high productivity by applying a surfactant and a specific amount of inert fine particles on the filament surface and a sufficient amount of silver- substituted antimicrobial zeolite in the filament. CONSTITUTION:The polyamide filament tow has a surfactant and inert fine particles on the surface and contains silver-substituted antimicrobial zeolite inside. The inert fine particles are preferably silica or the like. The particle pick-up is 0.01 to 1.0wt.% preferably 0.05 to 0.5wt.%, based on the fibers and enough to lower the abrasion resistance between the filaments on stretch breakage. The content of the silver-substituted zeolite depends on the amount of silver, and usually 0.01 to 20wt.%, preferably 0.1 to 2wt.%, based on the fiber.
