Double knitted fabric

Abstract

The invention is aimed to provide a double knitted fabric wherein a stitch loop portion of a linking yarn is not jutted forth from the surface of the webs, and characteristic of touch, texture and so forth peculiar to a material of a web-forming yarn on the surface is not impaired, providing good decency, capable of decreasing density of the linking yarn and reducing weight, preventing rubbing sound, and also bringing out proper compressive strength, elasticity in the direction of thickness. To provide these features, in the double knitted fabric comprising of the front and rear webs ( 1 ), ( 2 ) and the linking yarn ( 3 ) linking both webs, the linking yarn ( 3 ) is knitted in two-needle stitch, or in combination with two-needle stitch and one-needle stitch, on at least one of the front and rear webs.

         10 . The double knitted fabric according to  claim 8 , wherein a yarn made of a material of poor hardwearing properties or touch or a material of poor dyeing properties or color development properties is inlayed as a width-wise or a knitting-direction-wise inlay yarn to be inlayed between the web-forming yarn and the traverse-wise running portion of the linking yarn; and a yarn of good hardwearing properties or good touch or a material of good dyeing properties or color development properties is used as the web-forming yarn located outside of such inlayed yarn.  
     
     
         11 . The double knitted fabric according to  claim 9 , wherein a yarn made of a material of poor hardwearing properties or touch or a material of poor dyeing properties or color development properties is inlayed as a width-wise or a knitting-direction-wise inlay yarn to be inlayed between the web-forming yarn and the traverse-wise running portion of the linking yarn; and a yarn of good hardwearing properties or good touch or a material of good dyeing properties or color development properties is used as the web-forming yarn located outside of such inlayed yarn.  
     
     
         12 . The double knitted fabric according to  claim 8 , wherein the linking yarns being knitted in two-needle stitch on both of the front and rear webs; the knitting-direction-wise inlay yarn is inlayed between the web-forming yarn and the traverse-wise running portion of the linking yarn on each of the front and rear webs, so as to be passed between the front and rear webs.  
     
     
         13 . The double knitted fabric according to  claim 9 , wherein the linking yarns being knitted in two-needle stitch on both of the front and rear webs; the knitting-direction-wise inlay yarn is inlayed between the web-forming yarn and the traverse-wise running portion of the linking yarn on each of the front and rear webs, so as to be passed between the front and rear webs.

The double knitted fabric according to anyone of claims  1  through  17 , wherein web-forming yarns of at least one of the front and rear webs is jutted forth out of external surface of the webs; and the web-forming yarn jutted out of the external surface is raised and sheared.  
     
     
         19 . The double knitted fabric according to anyone of claims  1  through  18 , wherein at least one of the front and rear webs is knitted as marquisette tone by two-needle stitches of the linking yarns.  
     
     
         20 . The double knitted fabric according to anyone of claims  19 , wherein at least one of the front and rear webs is knitted in marquisette-tone knitting construction formed of stitch rows of chain stitch yarns extending in knitting direction, as well as of width-wise inlay yarns that are inlayed into said stitch rows as shifted by wales of one or several rows laterally at every plural number of courses; and 
 the linking yarns linking the front and rear webs are knitted by two guide bars and shifted in opposite direction with each other by the two guide bars, as to be knitted in two-needle stitch on each of the front and rear webs, at a course portion substantially corresponding to the traverse-wise running portion of the inlay yarn.
