two ground combs knit the base tissue layer, with ground comb GB1 warp knitting the base tissue 1-2/1-0//; the ground comb GB2 runs through the warp knitting basic structure 1-0/3-4//;

weaving jacquard layers by two jacquard combs, wherein the jacquard comb GB3 is warp-knitted basic tissues 4-3/3-4/7-6/6-7/4-3/3-4/1-0/3-4/4-3/3-4/4-3/3-4///by passing 1 through 7 empty weaving modes, and the jacquard comb GB4 is warp-knitted basic tissues 1-0/3-4/4-3/3-4/4-3/3-4/4-3/3-4/7-6/6-7/4-3/3-4///by passing 1 through 7 empty weaving modes;

the local oblique warp stitches 3-4/7-6 of jacquard combs GB3 and GB 4/the basic stitches 1-0/3-4// the extension threads of adjacent comb GB2 are all 3 in needle crossing distance and the same in needle crossing direction, and the extension threads of the ground comb GB2 cover the extension threads of the jacquard combs GB3 and GB4 to form a hidden thread jacquard layer.

10. The method of making a warp knitted concealed wire jacquard fabric according to claim 8, wherein: the warp knitting apparent and hidden line jacquard mesh fabric is warp knitting weft insertion type apparent and hidden line jacquard mesh fabric, and the knitting steps are as follows:

two ground combs knit the base tissue layer, with ground comb GB1 warp knitting the base tissue 1-2/1-0//; the ground comb GB3 runs through the warp knitting basic structure 1-0/3-4//;

a jacquard comb is used for weaving a jacquard layer, wherein the jacquard comb GB2 runs through warp knitting weft insertion basic weave 1-0/4-4/1-0/1-1//;

the spread lines of the partial pad lacking tissues 1-0/4-4 of the jacquard comb GB2 and the partial oblique tissues 1-0/3-4// of the ground combs GB1 and GB3 are all 3 in needle crossing distance and in needle crossing direction, and the spread lines of the jacquard comb GB2 cover the spread lines of the ground comb GB3 to form a pattern layer reaching the yarn display.
