Patent number: 6848281Abstract: A stretchable warp knitted fabric comprising warp knitting yarns, first weft in-laid yarns and second weft in-laid yarns, and stretchable warp in-laid yarns. The second weft in-laid yarns consist of a plurality of at least non-stretchable yarns, and said second weft in-laid yarns run sequentially and separately in the course direction on different wale regions of the same course with having an arbitrary length respectively, while crossing the first weft in-laid yarns between courses. Consequently, even when pulled in a longitudinal direction, because the separate second weft in-laid yarns influence each other independently, the fabric does not have a great amount of ruffling in a width direction thereof and thus the a flat surface is maintained wherein there is no narrowing in the middle of the longitudinal direction.Type: GrantFiled: May 6, 2003Date of Patent: February 1, 2005Assignee: YKK CorporationInventors: Mitsutoshi Ishihara, Toshiaki Takizawa, Eiji Nakayama

Publication number: 20050011232Abstract: A knitted surface fastener wherein pile loops are formed by knitting-in pile knitting yarns at the same time when a foundation fabric is knitted with foundation yarns. After the pile knitting yarns which form the pile loops stride between two or more wales to form loops, they are entangled with each stitch of the foundation yarns of three or more adjoining courses on a same wales continuously to form stitches. Of the stitches of the pile knitting yarns formed due to the pile knitting yarns entangled per each of the adjoining three or more courses, at least one or more stitches located in the middle are formed in a closed loop. Consequently, the necessity of back coating is eliminated and further, clearly square gaps are formed to achieve ventilation property and transparency.Type: ApplicationFiled: June 25, 2004Publication date: January 20, 2005Inventors: Mitsutoshi Ishihara, Eiji Nakayama

Patent number: 6565943Abstract: The present invention provides a surface fastener wherein necessary engaging strength is maintained for a long term, the surface fastener is flexible and has a favorable touch without prickly feeling even when male engaging elements formed of fibers are employed, and strange peeling noise is not generated. The surface fastener includes at least a large number of male engaging elements planted on a foundation cloth which is a woven or knitted fabric or a non-woven fabric and is formed of fibers, the surface fastener being engaged with and disengaged from a mating surface fastener.Type: GrantFiled: August 12, 1999Date of Patent: May 20, 2003Assignee: YKK CorporationInventors: Yoichi Kondo, Masashi Doi, Mitsutoshi Ishihara

Patent number: 6202264Abstract: The present invention provides a surface fastener made of a woven/knitted fabric which is extremely thin and flexible. Designs and the like on a rear face side of the fastener can be clearly seen through engaging elements and a substrate. Also, the fastener has a high productivity, thereby allowing a rational price setting.Type: GrantFiled: February 17, 1999Date of Patent: March 20, 2001Assignee: YKK CorporationInventor: Mitsutoshi Ishihara

Patent number: 4838044Abstract: A warp-knit tape is disclosed for use in hook-and-loop fasteners, which tape comprises a pile portion and selvage portions on opposite sides thereof, the pile portion including pile-loops arranged to extend longitudinally in a meandering fashion to prevent the same from tilting down flat on the surface of the tape.Type: GrantFiled: March 22, 1988Date of Patent: June 13, 1989Assignee: Yoshida Kogyo K. K.Inventors: Yoshio Matsuda, Mitsutoshi Ishihara
