  • Patent number: 10993491
    Abstract: The present invention discloses a water-absorbent quick-drying knitted fabric and application thereof. The fabric is a single-sided knitted fabric, the reverse side having a concave-convex structure, the height of the convex parts of the concave-convex structure being 40-150 ?m, and the fiber forming the convex parts being a polyester elastic fiber. The present knitted fabric has excellent water-absorbing and quick-drying properties, improving the comfort of wear and being suitable for use in manufacturing T-shirts, polo shirts, and the like.
    Type: Grant

  • Patent number: 8393282
    Abstract: A sewn product comprises fabrics having conductive yarns inserted each in a warp direction and a weft direction and disposed in a lattice at intervals, wherein at least two stitches in at least one place of seam are provided with a stitch interval of not more than 5 mm, and a surface resistance (R) between two points separated by 30 cm across at least one seam is according to the formula: R?1.0×1012?. A sewn product comprises fabrics having conductive yarns inserted each in a warp direction and a weft direction and disposed in a lattice at intervals, wherein in at least one place of seam a number of piles of clothing fabrics of seam allowance is 5 or more, and a surface resistance (R) between two points separated by 30 cm across at least one seam is R?1.0×1012?.

  • Publication number: 20100279572
    Abstract: A fabric comprises conductive yarns inserted each in a warp direction and a weft direction and disposed in a lattice at intervals, wherein at least either one of the conductive yarns in the warp direction or the weft direction is inserted as a double weave to be a float yarn on the surface that the conductive yarn becomes a float yarn in the double weave, wherein a ratio of the conductive yarn inserted as the double weave not covered by an orthogonal nonconductive yarn but exposed is not less than 50% in arithmetic average, and a ratio of the conductive yarns in the warp direction and the weft direction intersect and contact each other is not less than 40% in arithmetic average. Clothes comprise the fabric, wherein the conductive yarn is inserted as the double weave in an obverse side of the clothes.
