Patent number: 10876230Abstract: Provided is an elastic circular-knitted fabric that can be used for clothing such as underclothes, sportswear, or casual wear, and that is stretchable and has a pleasant feel. This elastic circular-knitted fabric contains knitted loops (c1) composed of non-elastic fibers, and knitted loops (c2) composed of non-elastic fibers and elastic fibers. The knitted loops (c2) composed of the non-elastic fibers and elastic fibers exist in the elastic circular-knitted fabric at a ratio of one course for every two courses. In a slope of the elongation stress curve in the warp direction and weft direction of the elastic circular-knitted fabric, a ratio (a2/a1) of a slope (a1) at 0-40% elongation to a slope (a2) at 40-80% elongation is no more than 1.0 in the respective directions, and the standard deviation of unevenness between the loops on the rear surface of the elastic circular-knitted fabric is 0.5 or below.Type: GrantFiled: October 10, 2017Date of Patent: December 29, 2020Assignee: Asahi Kasei Kabushiki KaishaInventors: Tetsuyuki Watanabe, Shoichi Akita
