[0039] The technical solution of the present invention is further described in detail below in conjunction with the embodiments and drawings.

[0040] Example 1

[0041] This embodiment provides a warp-knitted jacquard shoe upper with a woven heddle effect woven by a single jacquard warp knitting machine with 6 guide bars, and a manufacturing method thereof.

[0042] A warp-knitted jacquard shoe upper with a woven twisted heddle effect, comprising, in sequence, a base surface layer, a twisted warp jacquard layer, and a base bottom layer, wherein the base surface layer is formed by sequentially connecting two sets of reversely changing weft insertion structures and chain structures; the base bottom layer is formed by connecting chain structures; the twisted warp jacquard layer is formed by the missing pad structures of at least two jacquard bars, and the missing pad structures connect the base surface layer and the base bottom layer; the chain structures of the base surface layer and the base bottom layer are bound together front to back, and the knitting process is as follows:

[0043] Knitted on a single jacquard machine with six bars, the order from the front needle bed to the back needle bed is: GB1, GB2, GB3, JB4.1, JB4.2, GB5. Among them, the GB1, GB2, and GB5 bars act on the front needle bed, the GB3, GB6, and GB7 bars act on the back needle bed, and JB4.1 and JB4.2 act on the front and back needle beds.

[0044] The specific weaving process includes the following steps: the yarn lamination structure of each comb bar is as follows: Figure 1 As shown,

[0045] Braided basic surface layer structure: It is woven by GB1, GB2, and GB5; GB1 inserts the first yarn in a 1-through-1-empty manner to weave 0-0-0-0 / 2-2-2-2 / 0-0-0-0 / 4-4-4-4 / 2-2-2-2 / 4-4-4-4 / / variable weft inlay structure; GB2 inserts the second yarn in a 1-through-1-empty manner to weave 4-4-4-4 / 2-2-2-2 / 4-4-4-4 / 0-0-0-0 / 2-2-2-2 / 0-0-0-0 / / variable weft inlay structure; GB5 inserts the third yarn in a full-through manner to weave 1-0-0-0 / 0-1-1-1 / / chain structure;

[0046] Braided imitation hank jacquard layer weave: It is woven by JB4.1 and JB4.2. JB4.1 is fully threaded with the fourth yarn to weave a weave with no padding 1-1-1-1 / 1-1-1-1 / / . JB4.2 is fully threaded with the fifth yarn to weave a weave with no padding 1-1-1-1 / 1-1-1-1 / / .

[0047] Knitting the basic base weave: This is woven by comb bar GB3. GB3 is fully threaded with the sixth yarn, weaving a chain weave of 1-1-1-0 / 0-0-0-1 / / .

[0048] The jacquard weave of the woven fabric is as follows: Figure 2b As shown, at this time, the fourth yarn and the fifth yarn lack padding area overlap, then when the fourth yarn and the fifth yarn are different in color, the area can appear a two-color magic effect, and the pattern effect of the product is similar to the pattern effect of the woven heddle product. The positive organization of the product effect can refer to Figure 3 or Figure 4 ; The structural effect of woven heddle products is as follows Figure 6 As shown, it comprises 1 quilt yarn, 2 hanks, and 3 weft yarns. The warp knitted jacquard fabric of this embodiment has the pattern effect of woven hank products, while retaining the dimensional stability and strong wrapping characteristics of warp knitted products, and the coils are not easy to fall apart and have excellent durability.

[0049] In this embodiment, the first, second, and third yarns are 150D polyester high-elastic yarns; the third and fourth yarns are 150D cationic polyester yarns; the fifth yarn is 150D nylon yarn; and the sixth and seventh yarns are 150D polyester high-elastic yarns. After dyeing, the fourth and fifth yarns are different colors, creating a two-color magic effect.

[0050] The shoe upper of this embodiment formed by the above-mentioned manufacturing method includes a basic surface layer structure formed by a variable weft insertion structure and a chain structure woven by an ordinary comb bar acting on the front needle bed, a jacquard layer structure formed by a missing-pad structure woven by a jacquard comb bar acting on the front and rear needle beds, and a basic bottom layer structure formed by a chain structure woven by an ordinary comb bar acting on the rear needle bed, wherein the chain structure yarns of the basic surface layer structure and the chain structure yarns of the basic bottom layer are tied to each other to prevent the fabric from delamination, thereby further improving the stability of the shoe upper.

[0051] Example 2

[0052] This embodiment is an expanded embodiment of Example 1, and its difference from Example 1 lies in the configuration of the jacquard bar. In this embodiment, the imitation twang jacquard layer structure is woven: it is woven by JB4.1 and JB4.2, JB4.1 inserts the fourth yarn in a full-threading manner to weave a weft inlay structure 0-0-0-0 / 1-1-1-1, and JB4.2 inserts the fifth yarn in a full-threading manner to weave a missing pad structure 1-1-1-1 / 1-1-1-1 / / ; the rest of the weaving structure is the same as that of Example 1. At this time, the imitation twang jacquard layer structure of the fabric is formed by the missing pad structure of the jacquard bar JB4.2, which presents a monochrome imitation twang jacquard effect, and the inlay structure of the jacquard bar JB4.1 is as follows: Figure 2a As shown, the fabric structure diagram is as follows Figure 3 shown.

[0053] Example 3

[0054] This embodiment is another expanded embodiment of Example 1, and its difference from Example 1 lies in the configuration of the jacquard bar. In this embodiment, the imitation hank jacquard layer structure is woven: it is woven by JB4.1 and JB4.2, JB4.1 inserts the fourth yarn in a full-threading manner to weave a missing pad structure 1-1-1-1 / 1-1-1-1 / / , and JB4.2 inserts the fifth yarn in a full-threading manner to weave a weft insertion structure 0-0-0-0 / 1-1-1-1; the rest of the weaving structure is the same as that of Example 1. At this time, the imitation hank jacquard layer structure of the fabric is formed by the missing pad structure of the jacquard bar JB4.1, which presents a monochrome imitation hank jacquard effect, and the inlay structure of the jacquard bar JB4.2 is as follows: Figure 2a As shown, the fabric structure diagram is as follows Figure 4 shown.

[0055] Although the imitation twisted warp jacquard effects of Examples 2 and 3 are both monochrome patterns, their imitation twisted warp jacquard directions are different. Therefore, the inlay yarn structures of Examples 1, 2, and 3 can be changed on the same piece of fabric to achieve an imitation twisted warp jacquard with a two-color magic effect, or a monochrome imitation twisted warp jacquard can be formed to enrich the pattern effect of the shoe upper.

[0056] In addition, when both jacquard bars JB4.1 and JB4.2 are knitting weft-inserted fabrics, the hank-like jacquard layer is hidden, presenting a conventional woven-like fabric structure. Therefore, when the lapping weaves of the jacquard bars are configured according to design requirements, a richer variety of pattern effects can be presented.

[0057] Example 4

[0058] This embodiment provides a method for manufacturing a warp-knitted jacquard shoe upper with a woven heddle effect woven by a single jacquard warp knitting machine composed of 8 guide bars, and the shoe upper formed by the knitting.

[0059] Knitted on a single jacquard machine with eight bars, the order from the front needle bed to the back needle bed is: GB1, GB2, GB3, JB4.1, JB4.2, GB5, GB6, GB7. The bars GB1, GB2, and GB5 act on the front needle bed, the bars GB3, GB6, and GB7 act on the back needle bed, and JB4.1 and JB4.2 act on the front and back needle beds.

[0060] During the weaving process, the method for weaving the basic surface layer structure and the imitation twisted warp jacquard layer structure is the same as that of Example 1. The difference from Example 1 lies in the weaving of the basic bottom layer structure, specifically:

[0061] The basic bottom layer is woven by the bars GB3, GB6, and GB7. GB3 inserts the sixth yarn in full threading mode to weave a chain weave of 1-1-1-0 / 0-0-0-1 / / . GB6 inserts the seventh yarn in full threading mode to weave a weave of 1-1-1-0 / 1-1-2-3 / / . GB7 inserts the eighth yarn in full threading mode to weave a weave of 1-1-1-2 / 1-1-1-0 / / . When both jacquard bars are padded with the missing weave, the fabric structure on the reverse side is as follows. Figure 5 The addition of the inlay yarn structure of combing bars GB6 and GB7 can further stabilize the fabric structure and improve the stability of the product.

[0062] In this embodiment, the first, second and third yarns are 150D polyester high-elastic yarns; the third and fourth yarns are 100D cationic polyester yarns; the fifth yarn is 100D nylon yarn; and the sixth and seventh yarns are 100D polyester high-elastic yarns.

[0063] In the above embodiment, the yarn characteristics of the fourth and fifth yarns are primarily manifested in different yarn types. When dyed using different processes, they can exhibit different colors, thereby creating a two-color, hank-like jacquard effect or a single-color, hank-like jacquard effect by controlling the lapping structure of the jacquard bar. Furthermore, the yarn characteristics of the fourth and fifth yarns can also be manifested in different yarn colors. That is, when knitting with colored yarns, the different colors of the fourth and fifth yarns can achieve a two-color, hank-like effect. Furthermore, the yarn characteristics can also be different yarn gloss, for example, the fourth yarn is a colored yarn and the fifth yarn is a matte yarn, or different yarn thickness, for example, the fourth yarn is 150D and the fifth yarn is 100D. Furthermore, it is worth noting that the characteristics of the fourth and fifth yarns can be different in not only one characteristic, but also in two or more characteristics, including but not limited to any combination of the above characteristics, thereby achieving different hank-like effects.

[0064] The shoe upper of this embodiment formed by the above-mentioned manufacturing method comprises a surface layer, a bottom layer and a jacquard layer located between the surface layer and the bottom layer. Since the yarn types of the surface layer and the bottom layer are different from those of the jacquard layer, and the two yarn types of the jacquard layer are also different, their dyeing processes are different. After dyeing treatment, an imitation woven jacquard warp knitted fabric with a two-color twisted heddle effect is formed.

[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.
