  • Patent number: 11560655
    Abstract: The present invention discloses a hemming-stitch-free warp-knitted elastic fabric and a method for knitting thereof. The method includes: making a non-elastic yarn pass across a guide needle of the first guide bar and form the surface of the fabric by knitting via two needles or three needles in a 1×1 or 2×1 warp plain stitch loop mode, and making an elastic yarn pass across a guide needle of the second guide bar and form the inside of the fabric by knitting with the aforementioned non-elastic yarn in the same direction via three needles in a open double warp plain stitch loop mode, and two loops are continuously formed on each course of the open double warp plain stitch loop. The hemming-stitch-free warp-knitted fabric produced according to the present invention has good snagging grade, moderate horizontal straight tensile force and good resilience.

  • Publication number: 20210032786
    Abstract: The present invention discloses a free-cut warp-knitted elastic fabric with a hidden cross stripe and a method for knitting thereof. The method includes: making a non-elastic yarn pass across a guide needle of the first guide bar and form the surface of the fabric by knitting via three needles in an open warp sateen loop mode, and making an elastic yarn pass across a guide needle of the second guide bar and form the inside of the fabric by knitting with the aforementioned non-elastic yarn in the same direction via three needles in an open warp sateen loop mode. The warp-knitted fabric provided by the present invention can be arbitrarily cut, does not ravel easily, is free of hemming-stitch, and has a hidden cross stripe effect.

  • Publication number: 20200291556
    Abstract: The present invention provides a free-cut warp-knitted elastic fabric and a method for production thereof. The method uses a first guide bar and a second guide bar of a tricot warp knitting machine for knitting, wherein a non-elastic yarn passes across a guide needle of the first guide bar and forms the surface of the fabric by knitting via two needles in a 1×1 warp plain stitch loop mode, and an elastic yarn passes across a guide needle of the second guide bar and forms the inside of the fabric by knitting with the aforementioned non-elastic yarn in the same direction via two needles in a 1×1 double warp plain stitch loop mode. Finally the fabric which has good resilience, can be arbitrarily cut, and has low raveling property, good elasticity and high snagging level is obtained.
