Abstract

A knitting method for a warp knitted jacquard three-color figured fabric comprising: (1) defining the basic traverse information of a jacquard bar in non-offset state; (2) A-color pattern area is composed of jacquard pattern texture and jacquard pattern needle supplement texture; (3) B-color pattern area is composed of jacquard pattern texture and jacquard pattern needle supplement texture; (4) a mesh structure of C-color ground net area is composed of jacquard mesh texture and ground bar texture; (5) a pattern contour area is formed by using two jacquard bars to bar the outer contour of the A-color pattern area or the outer contour of the B-color pattern area; (6) the elastic area is composed of a ground bar texture, and a ground bar is used to knit the elastic area texture.

Claims (59)

1. A knitting method for warp knitted three-color jacquard fabric produced on a high knitting gauge RSJ warp knitting machine,

wherein the RSJ warp knitting machine comprises two half knitting gauge jacquard bars forming a full knitting gauge bar for a same direction of a mat yarn movement,

wherein an order of machine bar from front to back is jacquard bar JB 1 . 1 , JB 1 . 2 , two stitch-forming guide bars GB 2 , GB 3 , and one weft insertion guide bar GB 4 ,

wherein the jacquard bar JB 1 . 1 is used in odd longitudinal lines,

wherein the jacquard bar JB 1 . 2 is used in even longitudinal lines,

wherein JB 1 . 1 and JB 1 . 2 are the two half knitting gauge jacquard bars and form a full knitting gauge bar,

wherein the stitch-forming guide bars GB 2 and GB 3 are full gauge knitting,

wherein the weft insertion guide bar GB 4 is full gauge knitting;

wherein the knitting method of the warp knitted three-color jacquard fabric comprises knitting the three-color jacquard fabric, which comprises an A-color pattern area, a B-color pattern area, a C-color ground mesh area, a pattern outline area, and an elastic area, wherein the specific knitting method comprises the steps of:

(1) defining basic traverse information of the jacquard bars JB 1 . 1 , JB 1 . 2 in a non-offset state:

wherein the specific corresponding action information of a lapping form and a jacquard needle is as follows:

the jacquard bar JB 1 . 1 : 1-0/1-2//(HH/HH//) is covered with A-color yarn;

the jacquard bar JB 1 . 2 : 1-0/1-2//(HH/HH//) is covered with B-color yarn;

the stitch-forming guide bars GB 2 , GB 3 are covered with C-color yarn;

the weft insertion guide bar GB 4 is covered with spandex yarn;

(2) knitting the A-color pattern area:

wherein the A-color pattern area is composed of a first jacquard pattern and a first jacquard replenishing pattern,

wherein a chain notation and offset state of the first jacquard pattern is:

JB 1 . 1 : 1-0/2-3//(HH/TT//),

JB 1 . 2 : 1-0/0-1//(TT/HH//);

and a chain notation and offset state of the first jacquard replenishing pattern is:

JB 1 . 1 : 1-0/2-3//(HH/TT//),

JB 1 . 2 : 1-0/1-2//(HH/HH//);

(3) knitting the B-color pattern area:

wherein the B-color pattern area is composed of a second jacquard pattern and a second jacquard replenishing pattern,

wherein a chain notation and offset state of the second jacquard pattern is:

JB 1 . 1 : 1-0/0-1//(TT/HH//),

JB 1 . 2 : 1-0/2-3//(HH/TT//),

and a chain notation and offset state of the second jacquard replenishing pattern is:

JB 1 . 1 : 1-0/1-2//(HH/HH//),

JB 1 . 2 : 1-0/2-3//(HH/TT//);

(4) knitting the C-color ground mesh area:

wherein the C-color ground mesh area is a mesh structure composed of a jacquard mesh pattern and a first ground bar pattern;

(5) knitting the pattern outline area:

wherein the pattern outline comprises A-color pattern contour structure and B-color contour pattern used, respectively, for an outer contour of the A-color pattern area and an outer contour of the B-color pattern area,

wherein the pattern of the pattern outline area is formed by the two half knitting gauge jacquard bars,

wherein a chain notation of the A-color pattern contour structure is:

JB 1 . 1 : 1-0/1-2//(HH/HH//),

JB 1 . 2 : 1-0/0-1//(TT/HH//),

and a chain notation of the B-color contour pattern is:

JB 1 . 1 : 1-0/0-1//(TT/HH//),

JB 1 . 2 : 1-0/1-2//(HH/HH//);

(6) knitting the elastic area: consisting of a second ground bar pattern which uses a ground bar to knit the elastic area.

2. The method of claim 1 , wherein in the step (4), the jacquard mesh pattern is formed by jacquard chain stitches,

wherein the chain notation and offset information of jacquard chain stitch is:

JB 1 . 1 : 1-0/0-1//(TT/HH//);

JB 1 . 2 : 1-0/0-1/(TT/HH//);

wherein the two stitch-forming guide bars GB 2 and GB 3 are used in the first ground bar pattern,

wherein the chain notation is:

GB 2 : 2-3/2-1/1-2/1-0/1-2/2-1//,

GB 3 : 1-0/1-2/2-1/2-3/2-1/1-2//.

3. The method of claim 1 , wherein in the (4), the jacquard mesh pattern is formed by a jacquard chain structure, and the two stitch-forming guide bars GB 2 and GB 3 are used as compacting patterns to form ground bar patterns,

wherein the chain notation is:

GB 2 : 1-0/0-1//, and

GB 3 : 0-0/2-2//.

4. The method of claim 1 wherein in the step (6), the chain notation of the weft insertion guide bar to form the second ground bar pattern is:

GB 4 : 1-1/0-0//.

5. The method of claim 1 wherein the bar JB 1 . 1 is threaded with 20D semi-dull PET filaments, and the bar JB 1 . 2 is threaded with 20D polyester semi-dull filaments, the bars GB 2 and GB 3 are threaded with 20D semi-dull PET filaments, the bar GB 4 is threaded with 70D spandex yarns,
