Method for manufacturing a non-run elastic fabric

Abstract

Described herein is a method for manufacturing a non-run elastic fabric on weaving machines with loom of a warp/weft type having two weft-taker bars and a needle bar, consisting in prearranging a rigid thread ( 2 ) on one of the two weft-taker bars and an elastic thread ( 3 ) on the other weft-taker bar, and consisting moreover in arranging a rigid thread ( 2 ) and an elastic thread ( 3 ) in phase with one another and according to a weave having a periodicity of four stitches, in which three consecutive stitches are obtained on three different consecutive needles.

1 . A method for manufacturing a non-run elastic fabric on warp knitting machines having two thread guide bars and a needle bar, consisting in: prearranging a rigid thread ( 2 ) on one of said thread guide bar and an elastic thread ( 3 ) on the other of said thread guide bars, in arranging said rigid thread ( 2 ) and said elastic thread ( 3 ) in phase with one another, and according to a weave having a periodicity of four stitches, in which three consecutive stitches are obtained on three different consecutive needles. 
   
   
       2 . The method according to  claim 1 , in which said rigid thread ( 2 ) and said elastic thread ( 3 ) are arranged parallel to one another. 
   
   
       3 . The method according to  claim 1 , in which said needles are prearranged on said needle bar with a density comprised between 32 and 44 needles per inch. 
   
   
       4 . The method according to  claim 3 , in which said needles are prearranged on said needle bar with a density comprised between 40 and 44 needles per inch. 
   
   
       5 . The method according to  claim 1 , in which a weave is provided presenting a closed stitch alternating with an open stitch. 
   
   
       6 . The method according to  claim 1 , in which said rigid thread ( 2 ) is provided with a linear density comprised between 22 and 44 dTex. 
   
   
       7 . The method according to  claim 1 , in which said elastic thread ( 3 ) is provided with a linear density comprised between 33 and 44 dTex. 
   
   
       8 . The method according to  claim 1 , in which said rigid thread ( 2 ) and said elastic thread ( 3 ) are provided with a ratio between the linear densities comprised between 0.5 and 0.9. 
   
   
       9 . The method according to  claim 1 , in which said thread guide bars are set one at the front and one at the rear and in which said rigid thread ( 2 ) is set on said front bar. 
   
   
       10 . A fabric obtained starting from a basic portion, including a rigid thread ( 2 ) and an elastic thread ( 3 ), disposed in phase with said rigid thread ( 2 ) and said elastic thread ( 3 ) being furthermore disposed in accord to an Atlas weave with periodicity of four stitches. 
   
   
       11 . The fabric according to  claim 10 , in which said rigid thread ( 2 ) and said elastic thread ( 3 ) are arranged parallel to one another. 
   
   
       12 . The fabric according to  claim 10 , in which said rigid thread ( 2 ) is provided with a linear density comprised between 22 and 44 dTex. 
   
   
       13 . The fabric according to claim from  10 , in which said elastic thread ( 3 ) is provided with a linear density comprised between 33 and 44 dTex. 
   
   
       14 . The fabric according to  claim 10 , in which said rigid thread ( 2 ) and said elastic thread ( 3 ) are provided with a ratio between the linear densities comprised between 0.5 and 0.9.
