Patent number: 7631521Abstract: A garment that is made including a piece of a stretchable warp-knitted fabric, wherein at least a non-elastic yarn is arranged in a 1×1 tricot structure and an elastic yarn is arranged in a looping structure, that is cut at an angle of at least 3° and at most 177° with respect to the knitting direction, the piece having an edge that does not require hem finishing when left as cut, so that at least one of the edge portions of the garment is formed by an edge that does not require hem finishing when left as cut (an edge of the bottom line 2 or an edge of the waist line 3). Thus, a garment is provided, in which the portion of the edge does not become thick, the edge does not require hem finishing when the fabric is left as cut, this edge is used for the garment's edge portion, curling of the edge portion does not occur, and the edge portion fits the body.Type: GrantFiled: April 26, 2004Date of Patent: December 15, 2009Assignee: Wacoal CorporationInventor: Kei Oya

Patent number: 7395681Abstract: The present invention provides stretchable warp-knitted fabric that is a 1×1 tricot formed by running a non-elastic yarn and an elastic yarn side by side in such a manner that in each stitch, at least one of the non-elastic yarn and the elastic yarn forms a closed loop, a method for manufacturing the fabric, and stretchable clothing using the fabric at least in a part. Since a cut edge of the knitted fabric can be used as a hem of the clothing without finishing, sewing is simplified. It is possible to provide fashionable clothing that has appropriate stretchability enabling the clothing to well fit the body of the wearer, that is thin and has a beautiful texture, and that, when it is formed in underwear, has a hem line invisible through outerwear.Type: GrantFiled: December 28, 2005Date of Patent: July 8, 2008Assignee: Wacoal Corp.Inventors: Kei Oya, Masami Saito, Mayumi Ogawa, Ikuhiro Yamada, Yasue Kawashima

Patent number: 6401497Abstract: A garment with a figure control or muscle support function which includes a warp knit fabric having ground stitches by jacquard knitting of inelastic yarn, in which elastic yarn is further inserted and/or knitted. Portions with relatively strong and weak straining forces are formed in the warp knit fabric in predetermined places in predetermined patterns by changing the ground stitches depending on the required strength of the straining forces. There is substantially no difference in level at a boundary between the portions with strong and weak straining forces. The fabric is thus free of a problem in which a difference in level is reflected in outer wear and degrades the wearer's appearance.Type: GrantFiled: October 19, 2000Date of Patent: June 11, 2002Assignee: Wacoal Corp.Inventors: Naruo Nishiyama, Kei Oya, Eiko Takagi, Yasuo Ishimoto
