Knitted fabric with reduced cracks, knitting method therefor, and design system using the knitting method

Abstract

A knitting method for knitting, by a double knit electric jacquard circular knitting machine with needle selection on dial and cylinder, a knitted fabric in which a pattern on a front face of the knitted fabric is knitted by using one of a cylinder and a dial, boundaries between motifs of the pattern in a wale direction being continuous at the same position in the wale direction in a plurality of successive courses, and a pattern on a back face of the knitted fabric is knitted by using the other of the cylinder and the dial. The knitted fabric is knitted such that knit structures adjacent, on the back face of the knitted fabric, to a border line in the wale direction that is formed by the boundary between the motifs on the front face of the knitted fabric in at least one course of the number of successive courses that is fewer by one than the number of types of jacquard knitting yarns used are successively knitted.

1 . A knitting method for knitting, by a double knit electric jacquard circular knitting machine with needle selection on dial and cylinder, a knitted fabric in which a pattern on a front face of the knitted fabric is knitted by using one of a cylinder or a dial, boundaries between motifs of the pattern in a wale direction being continuous at the same position in the wale direction in a plurality of successive courses, and a pattern on a back face of the knitted fabric is knitted by using the other of the cylinder or the dial,
 wherein the knitted fabric is knitted such that knit structures adjacent, on the back face of the knitted fabric, to a border line in the wale direction that is formed by the boundary between the motifs on the front face of the knitted fabric in at least one course of the number of successive courses that is fewer by one than the number of types of jacquard knitting yams used are successively knitted.   
     
     
         2 . The knitting method according to  claim 1 , wherein a portion on the back face of the knitted fabric comprises a repetition of a basic pattern, the portion corresponding to the motifs on the front face of the knitted fabric. 
     
     
         3 . The knitting method according to  claim 1 , wherein the knitted fabric is a quilted knit fabric. 
     
     
         4 . The knitting method according to  claim 1 ,
 wherein the pattern on the front face of the knitted fabric is a jacquard pattern in which a plurality of plain motifs are combined, the motifs having a certain area and being created with one of a plurality of types of yarns, and the pattern on the back face of the knitted fabric is an unusual bird's-eye pattern in which the yarns other than the yarn used for the front face of the knitted fabric are alternately knitted and welted for every course and every wale.   
     
     
         5 . The knitting method according to  claim 2 , wherein the basic pattern is composed of a plurality of wales and a plurality of courses. 
     
     
         6 . The knitting method according to  claim 2 , wherein the basic pattern is composed of 2 wales×2 courses, or 3 wales×3 courses. 
     
     
         7 . A knitted fabric knitted by a double knit electric jacquard circular knitting machine with needle selection on dial and cylinder, in which a pattern on a front face of the knitted fabric is knitted by using one of a cylinder or a dial, boundaries between motifs of the pattern in a wale direction being continuous at the same position in the wale direction in a plurality of successive courses, and a pattern on a back face of the knitted fabric is knitted by using the other of the cylinder or the dial,
 wherein the knitted fabric is knitted such that knit structures adjacent, on the back face of the knitted fabric, to a border line in the wale direction that is formed by the boundary between the motifs on the front face of the knitted fabric in at least one course of the number of successive courses that is fewer by one than the number of types of jacquard knitting yarns used are successively knitted.   
     
     
         8 . The knitted fabric according to  claim 6 , wherein a portion on the back face of the knitted fabric comprises a repetition of a basic pattern, the portion corresponding to the motifs on the front face of the knitted fabric. 
     
     
         9 . The knitted fabric according to  claim 6 , wherein the knitted fabric is a quilted knit fabric. 
     
     
         10 . The knitted fabric according to  claim 6 ,
 wherein the pattern on the front face of the knitted fabric is a jacquard pattern in which a plurality of plain motifs are combined, the motifs having a certain area and being created with one of a plurality of types of yarns, and the pattern on the back face of the knitted fabric is an unusual birds-eye pattern in which the yarns other than the yarn used for the front face of the knitted fabric are alternately knitted and welted for every course and every wale.   
     
     
         11 . The knitted fabric according to  claim 7 , wherein the basic pattern is composed of a plurality of wales and a plurality of courses. 
     
     
         12 . The knitted fabric according  claim 7 , wherein the basic pattern is composed of 2 wales×2 courses, or 3 wales×3 courses. 
     
     
         13 . A design system that automatically creates the patterns in the knitting method according to  claim 1 . 
     
     
         14 . The design system according to  claim 13 ,
 wherein the design system automatically creates a pattern on the back face of the knitted fabric by creating a pattern on the front face of knitted fabric, the pattern on the back face of the knitted fabric corresponding to the pattern on the front face of the knitted fabric.
