Warp knit and method of knitting the same

Abstract

A warp knit includes a plurality of warp yarns chain-stitched to form a plurality of wales for forming a ground weave and at least one pattern-forming yarn knitted into the ground weave, with the pattern-forming yarn having a course-wise knitted portion extending between the wales. In this warp knit, a thickness-increasing overlay yarn is knitted to be laid over the back side of the pattern-forming yarn at least over a portion of the course-wise knitted portion thereof. The thickness-increasing overlay yam has a greater elasticity than the pattern-forming yarn.

What is claimed is:  
     
         1 . A warp knit comprises: 
 a plurality of warp yarns chain-stitched to form a plurality of wales for forming a ground weave, and;    at least one pattern-forming yarn knitted into the ground weave, with the pattern-forming yarn having a course-wise knitted portion extending between the wales;    wherein the warp knit further comprises a thickness-increasing overlay yam knitted to be laid over the back side of the pattern-forming yarn at least over a portion of the course-wise knitted portion thereof, the thickness-increasing overlay yarn having a greater elasticity than the pattern-forming yarn.    
     
     
         2 . The warp knit according to    claim 1   , wherein the thickness-increasing overlay yarn is knitted under a greater tension than that applied to the pattern-forming yarn.  
     
     
         3 . The warp knit according to    claim 1    or    2   , wherein the thickness-increasing overlay yarn is knitted on a back side of an entire pattern-forming area of the knit where the pattern-forming yarn is knitted two-dimensionally to form an ornamental pattern.  
     
     
         4 . The warp knit according to    claim 1    or    2   , wherein the thickness-increasing overlay yarn is knitted on a back side of a predetermined portion of a pattern-forming area of the knit where the pattern-forming yarn is knitted two-dimensionally to form an ornamental pattern.  
     
     
         5 . The warp knit according to    claim 1    or    2   , wherein the thickness-increasing overlay yam is knitted along the course direction to be laid over the entire course-wise knitted portion of the pattern-forming yarn.  
     
     
         6 . The warp knit according to any one of claims  1 - 5 , wherein the pattern-forming yarn comprises a liner yam ranging from 200 denier to 300 denier.  
     
     
         7 . The warp knit according to    claim 1    or    2   , wherein a plurality of said pattern-forming yarns are knitted two-dimensionally to form a pattern-forming area on a front side of the knit, and said thickness-increasing overlay yarn is knitted to be laid over a back side of at least one or some of the plurality of pattern-forming yarns.  
     
     
         8 . A method of knitting a warp knit, comprising the steps of: 
 chain-stitching a plurality of warp yarns to form a plurality of wales for forming a ground weave, and;    knitting at least one pattern-forming yarn into the ground weave, with the pattern-forming yarn having a course-wise knitted portion extending between the wales;    wherein the method further comprises the step of knitting a thickness-increasing overlay yarn knitted to be laid over the back side of the pattern-forming yarn at least over a portion of the course-wise knitted portion thereof, the thickness-increasing overlay yarn having a greater elasticity than the pattern-forming yarn.
