[0042] Example 2

[0043] The present embodiment provides a warp-knitted jacquard fabric with a woven twisted heald effect, which includes a surface layer, a bottom layer, and a jacquard layer connected between the surface layer and the bottom layer. The jacquard layer exists in a part of the fabric. The surface layer forms a transverse extension effect of the coils through the weft-inserted tissue, and the warp-plain tissue woven by two comb bars forms a visual effect of two groups of coils extending longitudinally. The weft-inserted tissue and the two groups of warp-plain tissues are nested with each other, finally forming a visual effect of a woven twisted heald and having good air permeability. The jacquard layer is a chain-knitted tissue, which is used to form the jacquard effect of the surface layer, that is, to form a jacquard area 1, such as Figure 3As shown, it connects the surface layer and the bottom layer; when the surface layer does not need jacquard, the jacquard bars JB4.1 and JB4.2 perform 1-1-1-1 / 1-1-1-1 / / missing padding, and at this time there is no jacquard in this area, forming a non-jacquard area 2; the bottom layer is composed of two groups of warp plain weaves and one group of weft weaves woven by three bars, ensuring the horizontal and vertical stability of the fabric; the bar for one group of warp plain weaves is located in front of the bar for one group of warp plain weaves in the surface layer, so that the two groups of warp plain weaves are bound to each other, reinforcing the stability of the fabric. The weaving method is as follows:

[0044] A method for weaving a warp-knitted jacquard fabric with a woven twisted heddle effect, comprising the following steps:

[0045] (1) Equipment configuration: Select a single jacquard warp knitting machine with 8 combs. The combs are arranged from the front needle bed to the back needle bed on the single jacquard warp knitting machine in the following order: combs GB1, GB2, GB3, JB4.1, JB4.2, GB5, GB6, GB7; among them, combs GB1, GB2, GB5 act on the front needle bed, combs GB3, GB6, GB7 act on the back needle bed, and jacquard combs JB4.1 and JB4.2 act on the front and back needle beds;

[0046] (2) Weaving the surface layer: The comb bar GB1 is inserted into the first yarn in a full-threaded manner to weave a 0-0-0-0 / 3-3-3-3 / / structure; the comb bars GB2 and GB5 are inserted into 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;

[0047] (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 / / structure without padding. This is the non-jacquard layer, which is only used to connect the surface layer and the bottom layer;

[0048] (4) Weaving the bottom layer: Comb GB3 inserts the fifth yarn in a one-through-one-empty manner to weave a 1-1-1-0 / 1-1-1-2 / / structure. Comb GB6 inserts the sixth yarn in a full-through manner to weave a 1-1-1-2 / 1-1-1-0 / / structure. Comb GB7 inserts the seventh yarn in a full-through manner to weave a 0-0-0-0 / 3-3-3-3 structure.

[0049] In this embodiment, the first yarn and the second yarn are 100D polyester transparent monofilament; the third yarn is 150D / 48F polyester low-stretch yarn; the fourth yarn is 150D / 48F cationic polyester low-stretch yarn; the fifth yarn, the sixth yarn and the seventh yarn are 150D / 48F polyester low-stretch yarn.

[0050] After the fabric is woven, it can be washed, pre-shaped, dyed, shaped, and finished according to production needs to obtain the final product.

[0051] The weaving process sheet of this embodiment is shown in Table 1:

[0052] Table 1 Fabric weaving process sheet of Example 1

[0053]

[0054] Example 3

[0055] This embodiment is an extension of Example 1 and Example 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 shoe 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 through 1 empty, and performs 1-1-1-2 / 1-1-1-0 / / organization knitting; the comb GB5 moves on the rear needle bed, adopts 1 through 1 empty, and performs 1-2-1-1 / 1-0-1-1 / / organization knitting. The knitting methods of the remaining organizations are the same as those in the embodiment.

[0058] Comparative Example 2

[0059] In this comparative example, the knitting method in Example 1 is adjusted as follows: the comb bar GB7 is not threaded and knitted, and the rest of the structure is the same as 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 physical properties of various fabrics

[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 lower than that of the fabrics of Example 1 and Example 2. The reason is that 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 front is used to weave the bottom layer on the rear needle bed, while the comb bar GB5 arranged in the back is used to weave the surface layer on the front needle bed, the yarns of GB3 and GB5 will form a mutually bundled effect, thereby strengthening 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 shoe upper weaving 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 moisture absorption of the bottom layer of the fabric, yarns with better moisture absorption 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 that they do not destroy the overall imitation woven effect of the shoe upper.

[0065] The above are only preferred embodiments of the present invention, but do not limit the scope of the patent of the present invention. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the above embodiments or to 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 applied to other related technical fields, shall also fall within the scope of protection of the patent of the present invention.
