[0042] This embodiment provides a warp-knitted double-jacquard jacquard upper fabric with a splicing effect, as Figure 1As shown, the fabric is a single-sided fabric, including a first mesh area 1 and a second mesh area 1. The fabric is woven by 5 combs, and the arrangement of the combs is in turn Jacquard comb JB2.1, Jacquard comb JB2.2, Jacquard comb JB3.1, Jacquard comb JB3.2 and ground comb GB4. Among them, Jacquard comb JB2.1 weaves with the first yarn, Jacquard comb JB2.2 weaves with the second yarn, Jacquard comb JB3.1 weaves with the third yarn, Jacquard comb JB3.2 weaves with the fourth yarn, and ground comb GB4 weaves with the fifth yarn. Among them, the first yarn and the second yarn are 150D cationic polyester low-elastic yarns, the third yarn and the fourth yarn are 150D polyester low-elastic yarns, and the fifth yarn is 30D TPU monofilament. Jacquard comb JB2.1 weaves the basic organization of 1-1-1-0 / 1-1-1-2 / / , Jacquard comb JB2.2 weaves the basic organization of 1-1-1-2 / 1-1-1-0 / / , and the two combs weave the mesh organization in opposite directions to form the mesh structure of the first mesh area 1. Specifically:

[0043] As Figure 2 shown, the yarns in this embodiment are formed through the following organizations: The first mesh area 1 includes the Jacquard organization of 1-1-1-0 / 1-1-2-3 / / or 1-1-1-0 / 1-1-1-2 / / formed by the first yarn, the Jacquard organization of 1-1-2-3 / 1-1-1-0 / / or 1-1-2-3 / 1-1-2-1 / / formed by the second yarn, the Jacquard organization of 1-1-1-1 / 1-1-2-2 / / formed by the third yarn, and the Jacquard organization of 1-1-2-2 / 1-1-1-1 / / formed by the fourth yarn. Due to the arrangement order of the combs, only the first yarn and the second yarn are presented on the front of the first mesh area 1, and the third yarn and the fourth yarn are presented on the back of the first yarn and the second yarn;

[0044] Jacquard comb JB3.1 weaves the basic organization of 1-1-1-0 / 1-1-1-2 / / , JB3.2 weaves the basic organization of 1-1-1-2 / 1-1-1-0 / / , and the two combs weave the mesh organization in opposite directions to form the mesh structure of the second mesh area 1. Specifically:

[0045] The second mesh area 1 includes the Jacquard structures formed by the third yarn, such as 1-1-1-0 / 1-1-2-3 / / or 1-1-1-0 / 1-1-1-2 / / , the Jacquard structures formed by the fourth yarn, such as 1-1-2-3 / 1-1-1-0 / / or 1-1-2-3 / 1-1-2-1 / / , the Jacquard structure formed by the first yarn, such as 1-1-1-1 / 1-1-2-2 / / , and the Jacquard structure formed by the second yarn, such as 1-1-2-2 / 1-1-1-1 / / . Due to the arrangement order of the combs, both the front and back of the second mesh area 1 present the third and fourth yarns, and the first and second yarns are located between the back extension lines of the third and fourth yarns and the front coils;

[0046] The chain stitch structure formed by the fifth yarn fixes the Jacquard structures of the third and fourth yarns in the first mesh area 1 to the back of the Jacquard structures of the first and second yarns in the first mesh area 1, and fixes the Jacquard structures of the first and second yarns in the second mesh area 1 between the coils and extension lines of the third and fourth yarns, enhancing the stability of the fabric. Moreover, the fifth yarn is a transparent monofilament, which has almost no influence on the color blocks of the opposite layer, so that the front of the fabric presents a pure effect of spliced mesh color blocks. As Figure 3 shown, it is the guide bar pattern of the rectangular opposed draw mesh in the mesh area. As Figure 4 shown, it is the guide bar pattern of the diamond opposed draw mesh in the mesh. The shape of the mesh can be adjusted by the arrangement of the guide bar pattern.

[0047] The fabric of this embodiment is obtained by the following manufacturing method:

[0048] (1) Select equipment: Select a single-sided or double-sided double Jacquard warp knitting machine, and select at least 4 Jacquard combs and 1 ground comb. The combs are arranged from front to back in sequence as Jacquard comb JB2.1, Jacquard comb JB2.2, Jacquard comb JB3.1, Jacquard comb JB3.2 and ground comb GB4;

[0049] (2) Threading: The Jacquard comb JB2.1 is threaded with the first yarn, the Jacquard comb JB2.2 is threaded with the second yarn, the Jacquard comb JB3.1 is threaded with the third yarn, the Jacquard comb JB3.2 is threaded with the fourth yarn, and the ground comb is threaded with the fifth yarn. All combs are fully threaded; among them, the first and second yarns are 150D cationic polyester low elastic yarns, the third and fourth yarns are 150D polyester low elastic yarns, and the fifth yarn is 30D TPU monofilament;

[0050] (3) The first yarn is woven with a 1-1-1-0 / 1-1-2-3 / / or 1-1-1-0 / 1-1-1-2 / / Jacquard weave, the second yarn is woven with a 1-1-2-3 / 1-1-1-0 / / or 1-1-2-3 / 1-1-2-1 / / Jacquard weave, the third yarn is woven with a 1-1-1-1 / 1-1-2-2 / / Jacquard weave, the fourth yarn is woven with a 1-1-2-2 / 1-1-1-1 / / Jacquard weave, and the fifth yarn is woven with a chain stitch weave to jointly form the first mesh area 1; the third yarn is woven with a 1-1-1-0 / 1-1-2-3 / / or 1-1-1-0 / 1-1-1-2 / / Jacquard weave, the fourth yarn is woven with a 1-1-2-3 / 1-1-1-0 / / or 1-1-2-3 / 1-1-2-1 / / Jacquard weave, the first yarn is woven with a 1-1-1-1 / 1-1-2-2 / / Jacquard weave, the second yarn is woven with a 1-1-2-2 / 1-1-1-1 / / Jacquard weave, and the fifth yarn is woven with a chain stitch weave to jointly form the second mesh area 1.

[0051] (4) Dyeing: The woven fabric is dyed. Since the dyeing conditions of polyester and cationic polyester are different, when the colors of the dyes used for the two yarns are different, the front sides of the first mesh area 1 and the second mesh area 1 of the dyed fabric present different colors.

[0052] After dyeing, finishing processes such as setting the fabric are also required according to needs to meet the requirements of subsequent production.

[0053] In addition, colored yarns can also be used. For example, the first yarn and the second yarn are 150D cationic red polyester low-elastic yarns, the third yarn and the fourth yarn are 150D green polyester low-elastic yarns, and the fifth yarn is 30D TPU monofilament; then the front sides of the first mesh area 1 and the second mesh area 1 of the woven fabric present different colors, and the woven fabric does not need to be dyed, and only post-treatment processes such as pre-washing treatment or setting are required according to needs.

[0054] Example 2

[0055] This example is an extension of Example 1. In addition to the mesh areas in Example 1, the fabric of this example also includes plain weave areas. Specifically, the fabric further includes a first plain weave area, and the first plain weave area includes 1-1-1-0 / 1-1-2-3 / / Jacquard weaves formed by the first yarn and the second yarn respectively and 1-1-2-3 / 1-1-1-0 / / Jacquard weaves, and 1-1-1-1 / 1-1-2-2 / / Jacquard weaves formed by the third yarn and the fourth yarn respectively and 1-1-2-2 / 1-1-1-1 / / Jacquard weaves. The fabric also includes a chain stitch weave 1-1-1-0 / 0-0-0-1 / / formed by the fifth yarn, as Figure 5 shown in the diagram of the laying-in stitch as follows.

[0056] In addition to the manufacturing process in Example 1, the manufacturing process of this fabric further includes:

[0057] The first yarn and the second yarn are respectively knitted into 1-1-1-0 / 1-1-2-3 / / Jacquard weave and 1-1-2-3 / 1-1-1-0 / / Jacquard weave, the third yarn and the fourth yarn are respectively knitted into 1-1-1-1 / 1-1-2-2 / / Jacquard weave and 1-1-2-2 / 1-1-1-1 / / Jacquard weave, and the fifth yarn is knitted into chain stitch, jointly forming the first plain weave area.

[0058] The yarns used in this example are the same as those in Example 1. The texture of the plain weave area is relatively delicate and has good stability, and can be configured according to needs.

[0059] Example 3

[0060] This example is an extended example of the above example. On the premise of the above example, the fabric in this example further includes a second plain weave area. The second plain weave area includes 1-1-1-1 / 1-1-2-2 / / Jacquard weave and 1-1-2-2 / 1-1-1-1 / / Jacquard weave formed by the first yarn and the second yarn, and 1-1-1-0 / 1-1-2-3 / / Jacquard weave and 1-1-2-3 / 1-1-1-0 / / Jacquard weave formed by the third yarn and the fourth yarn.

[0062] In addition to TPU monofilament, the monofilament in the above example can also be any one of transparent monofilaments in the prior art such as polyester monofilament and nylon monofilament.

[0063] Example 4

[0064] The mesh holes in the first mesh area 1 and / or the second mesh area 1 in this example are one of rectangle, ellipse or rhombus. The mesh shape, size and density are realized by controlling the arrangement mode of the mesh holes and the plain weave structure, as Figures 6 - 9 shown, which are the design drawings of different mesh shapes:

[0065] Among them,Figure 6 As shown, it is a design drawing of a rectangular hole structure, Figure 7 As shown, it is a design drawing of a small diamond-shaped hole structure, Figure 8 As shown, it is a design drawing of a large diamond-shaped hole structure, Figure 9 It is a design drawing of an oval hole.
