(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 ### Claim 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 JB1.1, JB1.2, two stitch-forming guide bars GB2, GB3, and one weft insertion guide bar GB4, wherein the jacquard bar JB1.1 is used in odd longitudinal lines, wherein the jacquard bar JB1.2 is used in even longitudinal lines, wherein JB1.1 and JB1.2 are the two half knitting gauge jacquard bars and form a full knitting gauge bar, wherein the stitch-forming guide bars GB2 and GB3 are full gauge knitting, wherein the weft insertion guide bar GB4 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 JB1.1, JB1.2 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 JB1.1: 1-0/1-2//(HH/HH//) is covered with A-color yarn; the jacquard bar JB1.2: 1-0/1-2//(HH/HH//) is covered with B-color yarn; the stitch-forming guide bars GB2, GB3 are covered with C-color yarn; the weft insertion guide bar GB4 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: JB1.1: 1-0/2-3//(HH/TT//), JB1.2: 1-0/0-1//(TT/HH//); and a chain notation and offset state of the first jacquard replenishing pattern is: JB1.1: 1-0/2-3//(HH/TT//), JB1.2: 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: JB1.1: 1-0/0-1//(TT/HH//), JB1.2: 1-0/2-3//(HH/TT//), and a chain notation and offset state of the second jacquard replenishing pattern is: JB1.1: 1-0/1-2//(HH/HH//), JB1.2: 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: JB1.1: 1-0/1-2//(HH/HH//), JB1.2: 1-0/0-1//(TT/HH//), and a chain notation of the B-color contour pattern is: JB1.1: 1-0/0-1//(TT/HH//), JB1.2: 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. ### Claim 2 (depends on 1) 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: JB1.1: 1-0/0-1//(TT/HH//); JB1.2: 1-0/0-1/(TT/HH//); wherein the two stitch-forming guide bars GB2 and GB3 are used in the first ground bar pattern, wherein the chain notation is: GB2: 2-3/2-1/1-2/1-0/1-2/2-1//, GB3: 1-0/1-2/2-1/2-3/2-1/1-2//. ### Claim 3 (depends on 1) 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 GB2 and GB3 are used as compacting patterns to form ground bar patterns, wherein the chain notation is: GB2: 1-0/0-1//, and GB3: 0-0/2-2//. ### Claim 4 (depends on 1) 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: GB4: 1-1/0-0//. ### Claim 5 (depends on 1) The method of claim 1 wherein the bar JB1.1 is threaded with 20D semi-dull PET filaments, and the bar JB1.2 is threaded with 20D polyester semi-dull filaments, the bars GB2 and GB3 are threaded with 20D semi-dull PET filaments, the bar GB4 is threaded with 70D spandex yarns, wherein all the bars are covered with full yarn threading.
