  • Patent number: 11959206
    Abstract: Provided is a weft-knitted fabric having excellent stretchability, and providing excellent comfort in a hot environment. The weft-knitted fabric contains non-elastic fibres and elastic fibres, and is characterised: by being formed of a mesh part where a stitch of a welt structure and a stitch of a knit structure are alternately repeated to complete one course, and the course having the same structural arrangement is employed once or continuously repeated twice, and a plain-knit part where a course of an all-knit structure is employed once or continuously repeated up to three times; and in that said mesh part and said plain-knit part are each alternately arranged in the longitudinal direction.

  • Patent number: 11535964
    Abstract: Provided is a weft knit fabric with excellent raw edge properties and flexural softness. This weft knit fabric, which contains non-elastic yarns and elastic yarns and has a front surface and a back surface, is characterized in that: the elastic yarns connect the front surface with the back surface; the front surface and the back surface have portions wherein the non-elastic yarns and the elastic yarns form needle loops together; and the ratio of the number of sinker loops formed by the non-elastic yarns and the elastic yarns together with respect to the total number of sinker loops of the non-elastic yarns on the front surface and the back surface is not more than 50%.

  • Patent number: 11105026
    Abstract: Provided is a warp-knitted fabric having superior stretchability and feeling of coolness when worn and that can be cut and released without cut part of the knitted fabric curling. The warp-knitted fabric is knitted using synthetic fiber derived from a first reed, cellulose fiber derived from a second reed, and elastic yarn derived from a third reed and is characterized in that the proportion of the number of crossing points where the sinker loops of the synthetic fiber going across wales present in one complete course forming the warp-knitted fabric and the sinker loops of the elastic yarn to the number of sinker loops for the synthetic fiber going across the wales present in the one complete course is 50% or less.
