Publication number: 20230257938Abstract: An industrial two-layered fabric includes a front side fabric with warps and wefts and a back side fabric with warps and wefts. The front and back side fabrics are bound by binding warps. A first pair of warps consists of the front side warp and back side warp. A second pair of warps consists of two binding warps. A mutually complementary structure presents where one of the two binding warps forms consecutive knuckles on the front surface while another one of the two binding warps does not emerge on the front surface side, and where the another one of the two binding warps forms consecutive knuckles on the front surface whereas the one of the two binding warps does not emerge on the front surface side. A back side warp and an adjacent binding warp form knuckles below a one back side weft and another one back side weft.Type: ApplicationFiled: April 21, 2023Publication date: August 17, 2023Inventors: Ikuo Ueda, Kunio Nomura, Toru Egawa, Hideyuki Yanai

Patent number: 11668049Abstract: The object of the present invention is to provide an industrial two-layered fabric including binding wefts which is capable of improving a high adhesivity of the fabric on the front and back surface sides and the supportability of the warps, without deteriorating the surface smoothness, the abrasion resistance on the back surface side, the extension resistance in the longitudinal direction and the hydration property, which have been conventionally desired.Type: GrantFiled: March 13, 2019Date of Patent: June 6, 2023Assignee: NIPPON FILCON CO., LTD.Inventors: Ikuo Ueda, Kunio Nomura, Toru Egawa, Hideyuki Yanai

Publication number: 20210324552Abstract: In a multilayer fabric for nonwoven fabric 30, an upper-surface-side fabric formed from upper-surface-side warps (1Ub, 2U, 3U, 4U, 4U?, 5Ub, 6U, 7U, 8U, 8U?) and upper-surface-side wefts (1?U, 2?U, 3?U, 4?U) and a lower-surface-side fabric formed from lower-surface-side warps (1Lb, 2L, 3L, 5Lb, 6L, 7L) and lower-surface-side wefts (1?L, 2?L, 3?L, 4?L) are bound together. First warps (1Ub, 5Ub) of the upper-surface-side warps serve as first binding yarns that bind the upper-surface-side fabric and the lower-surface-side fabric, and second warps (1Lb, 5Lb) of the lower-surface-side warps serve as second binding yarns that bind the upper-surface-side fabric and the lower-surface-side fabric. A high-friction yarn is used as at least some of the upper-surface-side warps.Type: ApplicationFiled: June 25, 2021Publication date: October 21, 2021Inventors: Toru Egawa, Tsutomu Usuki, Keisuke Inoue

Publication number: 20210238784Abstract: According to the present invention, the curling or lifting of webs that occurs during the production nonwoven fabrics, and wrinkles that form on the surface of nonwoven fabrics are prevented. Also, the webs can be easily taken off without making grip stronger than necessary. The present invention pertains to an industrial fabric formed by weaving warp and weft, wherein an embossed pattern having a concavo-convex shape is formed in the vicinity of the apex of a knuckle portion exposed on the surface side of the warp and/or weft. In particular, the industrial fabric is characterized in that the warp and/or weft having the embossed pattern are plastic monofilaments.Type: ApplicationFiled: April 18, 2019Publication date: August 5, 2021Inventors: Keisuke Inoue, Toru Egawa, Hideyuki Yanai

Patent number: 10000869Abstract: An industrial two-layered fabric comprising an upper surface side fabric having an upper surface side warp and at least an upper surface side weft, and a lower surface side fabric comprising at least a lower surface side warp and at least a lower surface side weft bound by at least an upper surface side biding yarn and at least a lower surface side binding yarn, said industrial two-layered fabric is constituted by at least first pair of warps in which the upper surface side warp and the lower surface side warp are vertically arranged, at least second pair of warps in which the upper surface side binding yarn functioning as a binding yarn and the lower surface side binding yarn functioning as a binding yarn are vertically arranged, and at least third pair of warps where two upper surface side warps are adjacently arranged, said industrial two-layered fabric further comprises at least an auxiliary weft which isn't exposed to a surface of the fabric without being woven with any warp.Type: GrantFiled: March 4, 2014Date of Patent: June 19, 2018Assignee: NIPPON FILCON CO., LTD.Inventors: Toru Egawa, Fumihito Takahashi

Patent number: 9834870Abstract: An industrial two-layer fabric of the contact-yarn binding type without independent binding yarns, at both ends. The upper surface side warp serving as the warp fabric yarn-contact binding yarn is not woven into the upper surface side weft at one or more points of a complete structure, and extends toward the lower surface side instead and is woven into the lower surface side weft at the lower surface side, and then, extends toward the upper surface sides to be woven into other upper surface side weft, while, the lower surface side warp is not woven into the lower surface side weft at a point where the upper surface side warp serving as the warp fabric yarn-contact binding yarn is woven into the lower surface side weft at the lower surface side, and extends toward the upper surface side instead to be woven into the upper surface side weft which is not woven into the upper surface side warp, at the upper surface side, and then extends toward the lower surface side to be woven into other lower surface side weft.Type: GrantFiled: December 25, 2013Date of Patent: December 5, 2017Assignee: NIPPON FILCON CO., LTD.Inventors: Toru Egawa, Fumihito Takahashi

Patent number: 8991440Abstract: An industrial two-layer fabric has an inner space between an upper side fabric and a lower side fabric. Some or all of upper side wefts or lower side wefts are secondary wefts interwoven with upper side warps or lower side warps so as to make the number of warps passing on an upper surface of the upper side fabric or passing on a lower surface of the lower side fabric larger than that on an inner space side of the upper or lower side fabric and a long crimp in the inner space is formed by the secondary weft.Type: GrantFiled: March 15, 2013Date of Patent: March 31, 2015Assignee: Nippon Filcon Co., Ltd.Inventors: Ikuo Ueda, Toru Egawa, Yoshihisa Kondou
