Free-cut warp-knitted elastic fabric with hidden cross stripe and method for knitting thereof

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.

What is claimed is: 
     
         1 . A method for knitting a free-cut warp-knitted elastic fabric with a hidden cross stripe, which uses a first guide bar and a second guide bar of a warp knitting machine for knitting, comprising:
 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.   
     
     
         2 . The method according to  claim 1 , wherein modes for threading of the first guide bar and the second guide bar are full-set threading. 
     
     
         3 . The method according to  claim 1 , wherein the amount of let off of the non-elastic yarn is 85-120 cm/rack. 
     
     
         4 . The method according to  claim 1 , wherein the amount of let off of the elastic yarn is 45-75 cm/rack. 
     
     
         5 . The method according to  claim 1 , wherein the non-elastic yarn is a chemical filament. 
     
     
         6 . The method according to  claim 5 , wherein the fineness of the chemical filament is 11-85 dtex, preferably 22-56 dtex. 
     
     
         7 . The method according to  claim 1 , wherein the elastic yarn is a spandex yarn having a fineness of 22-77 dtex, preferably 22-56 dtex. 
     
     
         8 . A fabric, wherein the fabric is produced by using the method of  claim 1 . 
     
     
         9 . A garment, wherein at least a portion of a linear edge and/or a curved edge of the garment is composed of the fabric of  claim 8 .
