Description

Technical Field

[0001] This invention relates to the field of heddle fabric technology, specifically a double-layer heddle fabric and its preparation method, and a shoe upper. Background Technology

[0002] While traditional woven fabrics have seen improvements in texture and structure, innovative techniques combining double-layer design with scalloped structures are rare. Scalloped designs not only enhance the aesthetics of fabrics but also increase their breathability and comfort. Therefore, developing a method for efficiently and stably manufacturing double-layered scalloped fabrics is of great significance to the textile industry. Summary of the Invention

[0003] This invention provides a double-layer perforated fabric and its preparation method, as well as a shoe upper, which overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A double-layer pleated fabric includes a fabric body, which is divided into a face layer and a bottom layer. A separate pleated layer is provided in any local area of ​​the face layer and the bottom layer, and the two pleated layers form a double-layer structure. A number of pleated holes are provided on the pleated layer. A perforated structure is formed on the pleated layer by a perforated tulle weave. The structures of the two pleated layers are the same or different. The pleated holes superimposed on the other layer are displayed from one side of the face layer or the bottom layer through the perforated structure.

[0006] A preferred technical solution: A perforated area is provided at any identical position on the surface and bottom layers of the fabric body, which is formed by the upper warp needles rotating and twisting the lower warp to bind multiple weft yarns together.

[0007] A preferred technical solution: The non-double-layer structure area is a single-layer structure, which includes warp yarns and weft yarns, and the single-layer structure is composed of warp yarns and weft yarns interwoven together.

[0008] A preferred technical solution: The warp and weft yarns are made of colored yarns, and some areas are made of transparent elastic monofilaments, which are woven together to form a single-layer structure.

[0009] A preferred technical solution: the perforated area is located in any region of the fabric body.

[0010] A preferred technical solution: the transparent elastic monofilament is a thermoplastic polyester elastomer or a thermoplastic polyurethane elastomer.

[0011] A method for preparing a double-layer perforated fabric includes the following steps:

[0012] Step 1: Insert the corresponding weaving yarn into the warp yarn head. The weft yarn consists of several weft feeders. According to the needs of the shoe upper pattern, place each specification of yarn into the weft feeder in sequence.

[0013] Step 2: Start the loom. The loom interweaves the weft yarns with the warp yarns in a set order to form a layered fabric with a twill pattern.

[0014] Step 3: The fabric is pre-shrinked and set at a high temperature of 150℃-180℃ to make the whole fabric smoother.

[0015] A preferred technical solution: the braided yarn is a transparent monofilament or polyester yarn.

[0016] A double-layer perforated fabric upper, the upper being made of the aforementioned double-layer perforated fabric.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are:

[0018] In this invention, the double-layer grommet fabric is made by using a grommet weave process to create a texture with the same or different grommet shapes on both sides, where some warp yarns and the surface weft yarns, as well as some warp yarns and the bottom weft yarns, are connected. The structure formed by the superposition of the two grommet layers can be seen from either the surface or the bottom layer.

[0019] The double-layer twisted-hole fabric preparation method of the present invention can efficiently shape the double-layer twisted-hole fabric after efficient weaving, while ensuring the flatness of the fabric structure. Attached Figure Description

[0033] Example 1

[0034] like Figures 1-10 As shown, this embodiment provides a double-layer pleated fabric, including a fabric body 1. The fabric body 1 is divided into a surface layer 11 and a bottom layer 12. A separate pleated layer 13 is provided in any local area of ​​the surface layer 11 and the bottom layer 12, and the two pleated layers 13 form a double-layer structure. A plurality of pleated holes 131 are provided on the pleated layer 13. A perforated structure is formed on the pleated layer 13 by a perforated gauze weave. The structures of the two pleated layers 13 are the same or different. The pleated holes 131 superimposed on the other layer are displayed from one side of the surface layer 11 or the bottom layer 12 through the perforated structure.

[0035] Furthermore, at any identical position on the surface layer 11 and the bottom layer 12 of the fabric body 1, there is a perforated area formed by the upper warp needle rotating and twisting the lower warp to bind multiple weft yarns together, and several perforations 16 are formed on the perforated area.

[0036] Furthermore, the non-double-layer structure area is a single-layer structure, which includes warp yarn 14 and weft yarn 15, and the single-layer structure is formed by the interlacing of warp yarn 14 and weft yarn 15.

[0037] Furthermore, the warp yarns 14 and weft yarns 15 are woven with colored yarns and locally with transparent elastic monofilaments to form a single-layer structure.

[0038] Furthermore, the perforated area is located in any region of the fabric body 1.

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

[0040] In this embodiment, the double-layer heddle fabric forms a partially layerable and separable heddle layer 13 on the heddle fabric. The heddle layer 13 can be configured with heddle holes 131 of the same structure, and the heddle structure on the adjacent layers can be seen from either the top or bottom layer. The structural feature of the double-layer heddle fabric in this embodiment is not only its double-layer nature but also its partially double-layer heddle layer. The heddle structures on these two adjacent heddle layers can be flexibly configured to be the same or different, thereby combining to form different fabric structures. This changes the traditional heddle fabric's single-layer structure and further optimizes the structural style of the partially double-layer heddle fabric.

[0041] Example 2

[0042] This embodiment provides a method for preparing a double-layer perforated fabric, including the following steps:

[0043] Step 1: Insert the corresponding weaving yarn into the warp yarn head. The weft yarn consists of several weft feeders. According to the needs of the shoe upper pattern, place each specification of yarn into the weft feeder in sequence.

[0044] Step 2: Start the loom. The loom interweaves the weft yarns with the warp yarns in a set order to form a layered fabric with a twill pattern.

[0045] Step 3: The fabric is pre-shrinked and set at a high temperature of 150℃-180℃ to make the whole fabric smoother.

[0046] The preferred setting temperature is 160℃, but 150℃, 170℃, 180℃, or any value between 150℃ and 180℃ can be selected.

[0047] Furthermore, the braided yarn is a transparent monofilament or polyester yarn.

[0048] Example 3

[0049] This embodiment provides a method for preparing a double-layer perforated fabric, including the following steps:

[0050] Step 1: Design the shoe upper. Based on the relevant parameters of the shoe upper, use professional macro software to create an EP format file and input it into the loom. The warp yarn head is a pre-loaded transparent monofilament or polyester yarn. The weft yarn consists of 8 weft feeders. According to the needs of the pattern, place each specification of yarn in the weft feeder in sequence. Up to 8 weft yarns can be placed.

[0051] Step two: Start the loom and weave an initial product of a certain size, using the following weaving method. Figure 10 As shown, the weaving process proceeds from bottom to top. Red indicates the start of the first shuttle weft yarn, green indicates the start of the second shuttle weft yarn, and blue indicates the start of the third shuttle weft yarn. The machine automatically interweaves the weft yarns with the warp yarns in sequence. Black indicates the weft yarn sinking. In this version, red represents polyester yarn, green represents polyester yarn, and blue represents TPU monofilament.

[0052] Step 3: The initial product undergoes a high-temperature pre-shrinking and shaping process, with a shaping temperature of approximately 150 to 180 degrees Celsius, to make the entire piece more flat.

[0053] Step four: Create a design film copy, then cut the pieces, and finally laser process the shoe upper.

[0054] The double-layer twill weaving process of this invention can create a texture with a unique twill design in a double-layer fabric while ensuring the quality and stability of the fabric. Specific details are as follows:

[0055] The perforation is done by a double warp shaft machine. Figure 7 (The medium-coarse black yarn is the upper warp yarn, and the fine black yarn is the lower warp yarn);

[0056] Colored yarn (such as...) can be used on both sides of a single-layer structure. Figure 7 The warp and weft yarns are interwoven relatively tightly, and transparent elastic monofilaments such as TPU and TPEE high-strength yarns are used in some areas;

[0057] Layered perforations are created at arbitrary locations. One shuttle uses transparent elastic monofilaments such as TPU and TPEE high-strength yarns to create a perforated effect on the surface layer using a hollowed-out saluing structure. Other colored yarns also create a perforated effect on the bottom layer using a hollowed-out saluing structure, so that the two perforations are superimposed and displayed.

[0058] To create a see-through effect at any location, the see-through is formed by bundling multiple weft yarns together using a thicker needle at the top. (e.g., ...) Figure 9 ).

[0059] In the combination of the above three structures, a 160cm wide piece of material can be woven by machine first, then shaped and shrunk by high temperature, with localized warp layering, and combined with openwork gauze weave to achieve double-layer twill variation, giving the material a rich porous texture.

[0060] Example 4

[0061] This embodiment provides a double-layer perforated fabric upper, which is made of the aforementioned double-layer perforated fabric.

[0062] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
