The weaving method is as follows:

[0043] A method for weaving a warp knitted jacquard fabric with a woven twisted heald effect, comprising the following steps:

[0044] (1) Equipment configuration: A single jacquard warp knitting machine with 8 guide bars is selected. The guide bars are arranged from the front needle bed to the rear needle bed on the single jacquard warp knitting machine in the following order: guide bars GB1, GB2, GB3, JB4.1, JB4.2, GB5, GB6, GB7; among them, guide bars GB1, GB2, GB5 act on the front needle bed, guide bars GB3, GB6, GB7 act on the rear needle bed, and jacquard guide bars JB4.1 and JB4.2 act on the front and rear needle beds;

[0045] (2) Weaving the surface layer: the comb bar GB1 inserts the first yarn in a full-threading manner to weave a 0-0-0-0 / 3-3-3-3 / / structure; the comb bars GB2 and GB5 insert the second yarn in a one-thread-one-empty manner to weave a 1-0-1-1 / 1-2-1-1 / / and a 1-1-1-2 / 1-1-1-0 / / structure, respectively;

[0046] (3) Weaving jacquard layer and non-jacquard layer: In the jacquard layer, the jacquard bar JB4.1 inserts the third yarn in a full-threading manner to weave a 1-0-1-0 / 0-1-0-1 / / structure, and the jacquard bar JB4.2 inserts the fourth yarn in a full-threading manner to weave a 1-0-1-0 / 0-1-0-1 / / structure; in the non-jacquard layer, the jacquard bars JB4.1 and JB4.2 weave a 1-1-1-1 / 1-1-1-1 / / missing pad structure, which is a non-jacquard layer and is only used to connect the surface layer and the bottom layer;

[0047] (4) Weaving the bottom layer: the comb bar GB3 inserts the fifth yarn in a one-through-one-empty manner to weave a 1-1-1-0 / 1-1-1-2 / / structure. The comb bar GB6 inserts the sixth yarn in a full-through manner to weave a 1-1-1-2 / 1-1-1-0 / / structure. The comb bar GB7 inserts the seventh yarn in a full-through manner to weave a 0-0-0-0 / 3-3-3-3 structure.

[0048] In this embodiment, the first yarn and the second yarn are 100D polyester transparent monofilament; the third yarn is 150D / 48F polyester low-elastic yarn; the fourth yarn is 150D / 48F cationic polyester low-elastic yarn; the fifth yarn, the sixth yarn and the seventh yarn are 150D / 48F polyester low-elastic yarn.

[0049] After the fabric is woven, it can be washed, pre-shaped, dyed, shaped, and finished according to production needs to obtain the final product.

[0050] The weaving process sheet of this embodiment is shown in Table 1:

[0051] Table 1 Fabric weaving process sheet of Example 1

[0052]

[0053]

[0054] Example 3

[0055] This embodiment is an extended embodiment of Embodiment 1 and Embodiment 2, and the difference lies in the configuration of the yarn. In this embodiment, the sixth yarn and the seventh yarn are one of antibacterial yarns, far-infrared yarns or cool yarns. Since the bottom layer is in contact with the skin, the application of the functional yarns of the sixth yarn and the seventh yarn can give the upper better wearability.

[0056] Comparative Example 1

[0057] In this comparative example, the knitting method in Example 1 is adjusted as follows: the comb GB3 moves on the front needle bed, adopts 1 wear and 1 empty, and performs 1-1-1-2 / 1-1-1-0 / / structure knitting; the comb GB5 moves on the rear needle bed, adopts 1 wear and 1 empty, and performs 1-2-1-1 / 1-0-1-1 / / structure knitting; the knitting methods of the remaining structures are the same as those in the example.

[0058] Comparative Example 2

[0059] In this comparative example, the knitting method in Example 1 is adjusted as follows: the comb GB7 is not knitted with yarn, and the rest of the structure is the same as that in Example 1.

[0060] The physical properties of the fabrics of the above examples and comparative examples are shown in Table 2.

[0061] Table 2 Test results of various fabric properties

[0062]

[0063] It can be seen from the test results of the physical properties of each fabric that the strength of Comparative Example 1 and Comparative Example 2 is significantly smaller than that of the fabrics of Example 1 and Example 2. The reasons are as follows: for Comparative Example 1, since the GB3 comb bar is arranged in front of the GB5 comb bar, and during weaving, the comb bar GB3 arranged in the front is used for bottom layer weaving on the rear needle bed, and the comb bar GB5 arranged in the rear is used for surface layer weaving on the front needle bed, the yarns of GB3 and GB5 will form a mutually bound effect, thereby reinforcing the integrity of the fabric and improving its stability and strength; for Comparative Example 2, the weft-insertion structure with the yarns offset left and right by comb bar GB7 greatly increases the weft stability of the fabric, and is nested with the warp plain structure, thereby improving the overall strength.

[0064] It should be noted that the types of yarns provided in this embodiment are only some examples, and do not mean that only the above-mentioned yarns can be used. They include but are not limited to other types of yarns that can be used for weaving uppers in the prior art, such as cotton yarn, nylon, acrylic fiber, wool, silk, polypropylene, Tencel and other yarns. When achieving other effects, corresponding yarns can be selected accordingly. For example, in order to improve the hygroscopicity of the bottom layer of the fabric, yarns with better hygroscopicity can be selected, such as wool, cotton yarn, Tencel, etc.; for example, in order to improve the wear resistance of the surface layer of the fabric, nylon with excellent wear resistance can be selected, etc. However, it should be noted that when selecting the yarn, the yarn characteristics should be such as not to destroy the overall imitation woven effect of the upper.

[0065] The above are only preferred embodiments of the present invention, but do not limit the patent scope of the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features with equivalent ones. Any equivalent structure made by using the contents of the present invention specification, directly or indirectly used in other related technical fields, is also within the scope of patent protection of the present invention.
