Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0039] Referring to Figures 1 to 9 , a weaving process of a misaligned jacquard warp knitted fabric according to an embodiment of the present invention is carried out by a double needle bed warp knitting machine, and it includes the following steps:

[0040] Weaving preparation: The double needle bed warp knitting machine is configured with guide bars GB2, GB3, jacquard guide bar JB4-1, jacquard guide bar JB4-2, and guide bar GB5 from the front of the machine to the back of the machine. Guide bars GB2, GB3, and GB5 all adopt full machine number guide bar blocks, and jacquard guide bars JB4-1 and JB4-2 both adopt half machine number guide bar blocks. The guide bars on the guide bar block of jacquard guide bar JB4-1 and the guide bars on the guide bar block of jacquard guide bar JB4-2 are arranged alternately in sequence. The first yarn and the second yarn with different shades of color are respectively threaded through jacquard guide bar JB4-1 and jacquard guide bar JB4-2.

[0041] Weaving: Guide bars GB2 and GB3 jointly weave the bottom net surface layer 100. One side of the bottom net surface layer 100 is the observation surface. Guide bar GB5 weaves on the bottom net surface layer 100 to form a plurality of convex strips 200 arranged side by side in sequence on the observation surface. Jacquard guide bars JB4-1 and JB4-2 alternately carry out jacquard between the convex strips 200 and the bottom net surface layer 100. The first yarn and the second yarn are arranged in a cross between two adjacent convex strips 200. The included angle between the first yarn and the bottom net surface layer 100 between two adjacent convex strips 200 is an acute angle, and the included angle between the second yarn and the bottom net surface layer 100 between two adjacent convex strips 200 is an acute angle.

[0042] It can be understood that the initially configured guide bars of the double needle bed warp knitting machine include guide bar GB1, guide bar GB2, guide bar GB3, jacquard guide bar JB4-1, jacquard guide bar JB4-2, and guide bar GB5. Among them, in this embodiment, the weaving of the misaligned jacquard warp knitted fabric does not need to use guide bar GB1. Therefore, no threading work is done on guide bar GB1, and it is controlled that guide bar GB1 of the double needle bed warp knitting machine does not participate in the work.

[0043] It can be understood that both the jacquard bars JB4-1 and JB4-2 adopt half gauge guide bar blocks. The guide needles on the guide bar block of the jacquard bar JB4-1 and the guide needles on the guide bar block of the jacquard bar JB4-2 are arranged alternately in sequence. That is, in this embodiment, the half gauge guide bar blocks of the jacquard bar JB4-1 and the half gauge guide bar blocks of the jacquard bar JB4-2 can be regarded as a full gauge guide bar block in combination. Among them, the guide needles with odd numbers arranged on the regarded full gauge guide bar block are all located on the jacquard bar JB4-1, and the guide needles with even numbers arranged on the regarded full gauge guide bar block are all located on the jacquard bar JB4-2. For specific reference, Figure 5 and Figure 7 shown.

[0044] It can be understood that the multiple ridges 200 arranged side by side in sequence are at least three ridges 200 arranged side by side in sequence.

[0045] Through the above steps, on the observation surface of the fabric thus produced, the visual effect presented by the first yarn can be observed within a certain angular range, and the visual effect presented by the second yarn can be observed within another angular range. Among them, the above fabric can observe different visual effects within different angular ranges, and its effect is given by weaving without the need for post-treatment processes. Therefore, the production cost of the fabric can be reduced.

[0046] In this embodiment, the first yarn is a dark-colored yarn, and the second yarn is a light-colored yarn.

[0047] In some embodiments, the first yarn is a light-colored yarn, and the second yarn is a dark-colored yarn.

For reference, Figure 2 and Figure 3 , the yarn feeding methods of the bars GB2 and GB3 are both full feeding. The bars GB2 and GB3 jointly weave the bottom mesh surface layer 100 according to the laying-in numbers 12-22 / 10-00 / / and 10-00 / 23-33 / / respectively.

[0049] Through the above steps, the bottom mesh surface layer 100 woven by the bars GB2 and GB3 presents a twist and dense pattern effect, so as to further enrich the appearance effect of the color-mismatched jacquard warp knitted fabric.

[0050] In some embodiments, the bars GB2 and GB3 jointly weave the bottom mesh surface layer 100 in a mesh pattern.

[0051] The bar GB5 weaves on the bottom mesh surface layer 100. Specifically, the bar GB5 weaves on the bottom mesh surface layer 100 in a chain stitch. For reference,Figure 2 and Figure 4 The yarn feeding method of guide bar GB5 is full yarn feeding. Guide bar GB5 weaves on the bottom mesh surface layer 100 according to the guide bar pattern 10 - 10 / 01 - 01 / / .
