Method for knitting dense zones and knit obtained

Abstract

A method for the circular knitting of a knit including at least one dense zone, in which the dense zone(s) of the knit is or are achieved via knitting an alternation, in each row of stitches, of a first and second row of jersey stitches. The first row of jersey stitches is knitted on a first selection of needles, and includes knitting at least one tuck stitch within the row of jersey stitches, so as to form binding points with the sinker loops of the second row of stitches. The second row of jersey stitches is knitted with a second selection of needles and includes knitting with a reinforcing yarn in addition to the stitch-forming yarn. These dense zones can be used to increase the opaqueness of the knit at certain specific locations and thus create shapes for aesthetic purposes, or to reinforce the knit to make it more wear-resistant.

         6 . The method according to  claim 3 , further comprising the knitting of a weft yarn between each row of stitches, wherein the weft yarn is inserted between each row of stitches, by creating two or three or four consecutive floats which correspond to the needles which have knitted a stitch on the first row of stitches, the weft yarn being picked only every third needle or every fourth needle or every fifth needle respectively, and wherein the floats of the weft yarn are staggered relative to the next weft row, such that the floats are offset relative to each other from one weft row to the next. 
     
     
         7 . The method according to  claim 1 , wherein the dense zones, creating uniform geometric shapes evenly dispersed over the surface of the knit and whose total surface area of the dense zones is less than 10% of the total surface area of the knit, and preferably less than or equal to 5% of the total surface area of the knit. 
     
     
         8 . The method according to  claim 2 , further comprising the knitting of a weft yarn between each row of stitches, wherein the weft yarn is inserted between each row of stitches, by creating a float which corresponds to the needle which has knitted a load on the first row of stitches, the weft yarn being picked only every other needle, and wherein the floats of the weft yarn are produced in the same columns from one weft row to the next, such that the floats are aligned with each other. 
     
     
         9 . The method according to  claim 3 , further comprising the knitting of a weft yarn between each row of stitches, wherein the weft yarn is inserted between each row of stitches, by creating two or three or four consecutive floats which correspond to the needles which have knitted a load on the first row of stitches, the weft yarn being picked only every third needle or every fourth needle or every fifth needle respectively, and wherein the floats of the weft yarn are produced in the same columns from one weft row to the next, such that the floats are aligned with each other.
