Patent number: 10358748Abstract: A protective woven fabric of the present invention includes super fiber yarns. The warp of the woven fabric is a covered yarn (1, 4, 5) composed of two or more twisted inorganic filament yarns as core yarns (2a, 2b) and one or more super fiber yarns (3, 3a, 3b, 3c) as covering yarns that are wound and twisted around the core yarns (2a, 2b), and a weft thereof is a super fiber yarn. Preferably, the covered yarn is a W covered yarn in which a twist coefficient K of the covering yarns with respect to the core yarns is 2000 to 30000. Due to this, it is possible to provide a protective woven fabric that, even when the warp and the weft is squeezed or rubbed by the reed, heddles, etc., of a loom, has few defects such as fluff or fiber aggregates and which has a satisfactory weaving pattern while retaining a high protective function.Type: GrantFiled: January 18, 2016Date of Patent: July 23, 2019Assignee: The Japan Wool Textile Co., Ltd.Inventors: Ichiro Sugimoto, Keita Tasaki

Patent number: 9642399Abstract: A suit of the present invention is a two-piece suit (1) including a coat (2) and trousers (3) and/or a skirt that are made from a woven fabric containing animal hair fibers and/or synthetic fibers. The coat (2) stretches more in the weft direction than in the warp direction, and the trousers (3) and/or skirt stretch more in the warp direction than in the weft direction. A method for producing the suit includes: for upper and lower parts of the suit, dyeing yarns of the same quality by the same method and producing woven fabrics that are woven in the same structure; differentiating stretchability of the woven fabrics in warp and weft directions in tentering processing by a heat set in a final finish step, thereby producing a cloth for coat and a cloth for trousers and/or skirt; and cutting and sewing the cloths. Thus, it is possible to provide a suit imparted with a function of high mobility even though it is a two-piece suit, and a method for producing the same.Type: GrantFiled: November 15, 2012Date of Patent: May 9, 2017Assignee: The Japan Wool Textile Co., Ltd.Inventors: Takeichiro Baba, Hiroyuki Kondo, Norio Asakawa, Shuichi Tanaka

Publication number: 20130045653Abstract: A heat-resistant flame-retardant protective suit fabric of the present invention is formed of a uniform blended spun yarn including 25 to 75 mass % of polyetherimide fiber, 20 to 50 mass % of at least one fiber selected from wool and flame-retardant rayon, and 5 to 25 mass % of para-aramid fiber when the spun yarn is 100 mass %. The fabric experiences no heat shrinkage when exposed to a heat flux at 80 kW/m2 ±5% for 3 seconds in accordance with ISO 9151 Determination of Heat Transmission on Exposure to Flame. And the char length is not more than 10 cm in the longitudinal and horizontal directions in the flammability test specified in JIS L 1091A-4. Thereby, the present invention provides a protective suit fabric that provides comfort in wearing even if the suit is worn in the hot seasons or even if the wearer perspires during exertion. The fabric has high heat resistance and high flame retardance, favorable dye affinity, and the fabric can be produced at a low cost.Type: ApplicationFiled: January 12, 2012Publication date: February 21, 2013Applicants: SABIC INNOVATIVE PLASTICS IP B.V., THE JAPAN WOOL TEXTILE CO., LTD.Inventors: Masanobu Takahashi, Hideki Omori

Publication number: 20130040523Abstract: A protective suit fabric of the present invention is a heat-resistant flame-retardant protective suit fabric, which is formed of a spun yarn. The fiber blend rate is: 25-75 mass % of polyetherimide fiber (A); 20-50 mass % of at least one fiber (B) selected from wool and flame-retardant rayon; and 5 to 25 mass % of para-aramid fiber (C). The spun yarn for forming the fabric is a two-fold yarn (20) prepared by twisting: 1) a single yarn (24) of a uniform blended spun yarn including the fiber components (A) and (B); and 2) a single yarn (23) of a sheath-core spun yarn including a core (21) of stretch-broken spun yarn of the para-aramid fiber (C) and a sheath (22) formed by blend-spinning the polyetherimide fiber (A) and the at least one fiber (B) selected from wool and flame-retardant rayon. The protective suit fabric has high washing resistance. The protective suit fabric provides favorable comfort in wearing even if the suit is worn in the hot seasons or even if the wearer perspires during exertion.Type: ApplicationFiled: February 27, 2012Publication date: February 14, 2013Applicants: SABIC INNOVATIVE PLASTICS IP B.V., THE JAPAN WOOL TEXTILE CO., LTD.Inventors: Masanobu Takahashi, Hideki Omori

Patent number: 8209948Abstract: The multilayer-structured spun yarn of the present invention is a multilayer-structured spun yarn C composed of a core fiber A and a cover fiber B that wraps around the core fiber; the core fiber A is in a range of 20 to 50 wt %; the cover fiber B is in a range of 50 to 80 wt %; the core fiber A contains a para-aramid fiber and is a stretch breaking twist yarn; the cover fiber B contains a flame-retardant acrylic fiber, a polyetherimide fiber, or a meta-aramid fiber; the direction of twist of the stretch breaking yarn and the direction of twist of the multilayer-structured yarn are the same; and the multilayer-structured yarn C has a twist number 1.2 to 1.6 times greater than that of the stretch breaking yarn. The heat-resistant textile of the present invention uses the aforementioned multilayer-structured spun yarn. The heat-resistant protective suit of the present invention uses the aforementioned heat-resistant textile.Type: GrantFiled: July 10, 2008Date of Patent: July 3, 2012Assignees: The Japan Wool Textile Co., Ltd., Sabic Innovative Plastics IP B.V.Inventors: Masanobu Takahashi, Keita Tasaki, Yukimasa Tanimoto
