Example Embodiment
[0038] Example 1: Concave-convex effect formed laterally
[0039] On the E22 double needle bed warp knitting machine, six bars are used for knitting, and the distance of the looper board is 16mm. The fabric structure, threading and warp let-off are shown in Table 1:
[0040] Table 1
[0041]
[0042] When the distance of the knock-off plate is 16mm, the spacer wire of GB3 has 2 rows of normal loops on the front and rear needle beds, and the let-off amount of the loop is 17327mm / rack, but at this time the spacer wire of GB4 is the same on the front and rear needle beds. 2 When the loop is formed in a row, the let-off amount is greater than the normal let-off amount, which is 24000mm / rack. GB3 and GB4 have 10 courses of missing pads at the same time, that is, the 10 courses, the spacer yarn is not connected to the fabric of the front and rear needle beds, but in order to achieve the thickness of the GB4 connecting yarn area greater than the thickness of the GB3 connecting yarn area, t...

[0043] Example 2: Longitudinal formation of uneven effect
[0044] On the E18 double needle bed warp knitting machine, five bars are used for knitting, and the distance of the looper board is 16mm. The fabric structure, threading and warp let-off are shown in Table 2:
[0045] Table 2
[0046]
[0047] When the distance of the knock-off plate is 30mm, the spacer wire of GB3 has 2 courses of normal loop formation on the front and rear needle beds. The let-off amount when the loop is formed is 31679mm / rack, and the let-off amount when the 8 rows are missing is 29341mm / Rack, the yarn let-off amount of the first 200 courses remains unchanged. The let-off amount of the last 200 courses is changed. The let-off amount of loops in 2 rows is 42000mm / rack, and the amount of let-off for 8 rows is 40000mm / rack. Finally, after the surface material is composited and filled on the surface of the fabric, the thickness of the rear 200 course area is greater than the first 200 course area, such as ...

[0048] Example 3: Concave-convex effects are simultaneously formed horizontally and vertically
[0049] On the E22 double needle bed warp knitting machine, six bars are used for knitting, and the distance of the looper board is 30mm. The fabric structure, threading and warp let-off are shown in Table 3:
[0050] table 3
[0051]
[0052]
[0053] When the distance of the knock-off plate is 30mm, the spacer wire of GB3 has 2 courses of normal loop formation on the front and rear needle beds, the let-off amount when the loop is formed is 17327mm / rack, and the let-off amount when the 8 rows are missing is 6000mm / Rack, the interval wire let-off amount of the first 100 courses remains unchanged. In GB4, the warp let-off amount for normal loop formation of 2 rows of GB4 becomes 24000mm / rack, the warp let-off amount when the pad is missing for 8 rows is changed to 9000mm / rack, and the warp let-off amount of the spacer wire of the first 100 rows remains unchanged. The warp let-off amount ...
