[0032] Example 1

[0033] like Figure 1-Figure 8 As shown, this embodiment provides a layered fabric with a hole pattern, including a fabric body 1, the fabric body 1 is divided into a surface layer 2 and a bottom layer 3, a hole layer 21 layered with the bottom layer 3 is arranged at any local position on one side of the surface layer 2, and hole 211 is arranged on the hole layer 21. A hollow through-hole structure is formed on the hole layer 21 through a hollow gauze structure, and the bottom layer structure of the same size and shape can be seen from the side of the surface layer 2 through the hollow through-hole structure.

[0034] Furthermore, a perforated area formed by upper warp thick needles rotating and twisting lower warp to bundle multiple weft yarns is provided at any same position of the surface layer 2 and the bottom layer 3 of the fabric body 1, and the holes formed in the breathable area are perforated holes 6.

[0035] Furthermore, the non-layered structural area is a single-layer structure, the single-layer structure includes warp yarn 4 and weft yarn 5, and the single-layer structure is formed by interweaving warp yarn 4 and weft yarn 5. The perforated area is a single-layer structure, that is, it is non-layered, and the fabric structure at the breathable area is not two-layered when rubbed by hand, and the layers are not relatively separated.

[0036] Furthermore, the warp yarn 4 and the weft yarn 5 are woven together with colored yarn and partially transparent elastic monofilament to form a single-layer structure.

[0037] Furthermore, a patterned texture structure is formed on the bottom layer 3 by plain weaving.

[0038] Furthermore, the through-hole area is located in any area of ​​the fabric body 1 .

[0039] Furthermore, the transparent elastic monofilament is thermoplastic polyester elastomer (TPEE) or thermoplastic polyurethane elastomer (TPU).

[0040] By introducing the 211 texture and pattern design into the upper material, the upper has a unique sense of layering and visual beauty, while improving the breathability and comfort of the upper. The hollowing is a double warp beam machine. Among them, Figure 4The thick black is the upper warp yarn, and the thin black is the lower warp yarn.

[0041] In the single-layer structure, the front and back sides can use colored yarns to interweave the warp and weft yarns more closely, and transparent elastic monofilaments such as TPU, TPEE and other high-strength yarns can be used locally (the structure can be referred to Figure 4 );

[0042] Holes 211 and pattern layers are made at any local position, and one or more transparent elastic monofilaments such as TPU, TPEE and other high-strength yarns are used to make a hollow hole effect on the surface layer 2 using a hollow Sara weave. Other colored yarns are woven into a complex plain pattern texture on the bottom layer 3 to make it rich in layering.

[0043] (3) A through hole effect is made at any local position. The through hole position is formed by the upper warp thick needle rotating and twisting the lower warp to bundle multiple weft yarns 5 to form a through hole 6 (such as Figure 7 ).

[0044] In the combination of the above three structures, a material with a width of 160CM is first woven by a machine, and then it is shrunk by high temperature finishing, and the warp yarn 4 is partially used for layering. The surface layer 2 is combined with transparent monofilaments to implement reaming 211, and the pattern of the bottom layer 3 can be seen through the surface layer 2, making the pattern rich in layers.

[0045] The layered fabric with a hole pattern in this embodiment forms a double-layer structure that can be partially layered and separated on the twisted heddle fabric, and forms a corresponding hole layer structure on one side of the surface layer, enriching the structural style of the twisted heddle fabric. Different from the local double-layer structure on traditional warp knitted fabrics on the market, the emergence of the layered fabric with a hole pattern expands and innovates the traditional twisted heddle fabric with only a single-layer structure.

[0046] Example 2

[0047] This embodiment provides a hole pattern layered fabric upper, and the upper is made of the hole pattern layered fabric mentioned above.

[0048] Example 3

[0049] This embodiment provides a method for preparing a layered fabric with a treble pattern, comprising the following steps:

[0050] Step 1: The woven warp yarn 4 is placed in the corresponding weaving yarn, and the weft yarn 5 is composed of several weft accumulators. Each specification of yarn is placed in the weft accumulator in order according to the needs of the upper shape;

[0051] Step 2, starting the shuttle loom, the shuttle loom interweaves the weft yarn 5 with the warp yarn 4 in a set sequence to form a layered fabric with a quilted pattern;

[0052] Step three, subject the fabric to high-temperature pre-shrinkage and shaping treatment at a shaping temperature of 150°C-180°C to make the entire fabric smoother.

[0053] The setting temperature is preferably 160°C, and may be 150°C, 170°C, 180°C, or any point between 150°C and 180°C.

[0054] Example 4

[0055] This embodiment provides a method for preparing a layered fabric upper with a hole pattern, comprising the following steps:

[0056] Step 1: Before weaving, the upper needs to be designed according to the requirements. According to the relevant parameters of the upper, the EP format file is made with professional macro software and input into the shuttle loom; the corresponding weaving yarn is placed in the weft head of the woven warp yarn 4, and the weft yarn 5 is composed of eight weft storage devices. According to the needs of the upper shape, each specification of yarn is placed in the weft storage device in order, and eight weft yarns 5 can be placed;

[0057] Step 2, start the shuttle loom, the shuttle loom interweaves the weft yarn 5 with the warp yarn 4 in a set order to form a layered fabric with a skein pattern; the initial product with a total width of 160CM can be woven, and the weaving method is as follows Figure 8 As shown, weaving from bottom to top, red represents the first shuttle weft yarn, green represents the second shuttle weft yarn, blue represents the third shuttle weft yarn, and yellow represents the fourth shuttle weft yarn; the machine automatically interweaves the weft yarn with the warp yarn in sequence, and black represents the weft yarn sinking. In this version, red is polyester yarn, green is polyester yarn, blue is polyester yarn, and yellow is TPU monofilament;

[0058] Step 3: subject the fabric to high temperature pre-shrinkage and shaping treatment at a temperature of 150°C-180°C to make the entire fabric smoother;

[0059] Step 4: Design the film draft, cut the pieces, and then laser process the upper.

[0060] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
