Description

Technical Field

[0001] The utility model relates to the technical field of leno fabrics, in particular to a double-layer leno fabric and a shoe upper. Background Art

[0002] Although traditional woven fabrics have made progress in texture and structure, there are few innovative technologies that combine double-layer design with leno structure. The leno design can not only enhance the aesthetics of the fabric, but also increase its breathability and comfort. Therefore, developing a preparation method for efficiently and stably manufacturing double-layer leno fabrics is of great significance to the textile industry. Summary of the Utility Model

[0003] The utility model provides a double-layer leno fabric and a shoe upper, which overcome the deficiencies described in the background art.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0005] A double-layer leno fabric includes a fabric body, which is divided into a surface layer and a bottom layer. A separated leno layer is provided in any local area of the surface layer and the bottom layer, and the two leno layers form a double-layer structure. A number of leno holes are provided on the leno layer, and a hollow and breathable hole structure is formed on the leno layer through a hollow leno weave. The structures of the two leno layers are the same or different, and the leno holes superimposed with the other layer are displayed from one side of the surface layer or the bottom layer through the hollow and breathable hole structure.

[0006] A preferred technical solution: A through-hole area formed by twisting the upper warp with a thick needle to hold the lower warp and bundling multiple weft yarns together is provided at any same position of the surface layer and the bottom layer of the fabric body.

[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 formed by the interweaving of warp yarns and weft yarns.

[0008] A preferred technical solution: The warp yarns and weft yarns are woven with colored yarns and locally combined with transparent elastic monofilaments to form a single-layer structure.

[0009] A preferred technical solution: The through-hole area is located in any area of the fabric body.

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

[0012] Step 1, place the woven warp beam into the corresponding woven yarns. The weft yarns are composed of several weft accumulators, and each specification of yarn is placed in the weft accumulator in sequence according to the needs of the shoe upper pattern.

[0013] Step 2: Start the shuttle loom. The shuttle loom interweaves the weft yarns with the warp yarns in a set order to form a double-layer fabric with a knotted hole pattern.

[0014] Step 3: Subject the fabric to high-temperature pre-shrinking and setting treatment at a setting temperature of 150°C - 180°C to make the whole fabric more flat.

[0032] Example 1

[0033] As Figures 1-10 shown, this example provides a double-layer knotted hole fabric, including a fabric body 1. The fabric body 1 is divided into a surface layer 11 and a bottom layer 12. A separated knotted hole layer 13 is provided in any partial area of the surface layer 11 and the bottom layer 12, and the two knotted hole layers 13 form a double-layer structure. A number of knotted holes 131 are provided on the knotted hole layer 13. A hollow open-hole structure is formed on the knotted hole layer 13 through a hollow leno weave. The structures of the two knotted hole layers 13 are the same or different, and the knotted holes 131 superimposed with the other layer are shown from one side of the surface layer 11 or the bottom layer 12 through the hollow open-hole structure.

[0034] Furthermore, a porous area formed by rotating and twisting the upper warp yarns around the lower warp yarns to bundle multiple weft yarns together is provided at any same position of the surface layer 11 and the bottom layer 12 of the fabric body 1, and a number of porous holes 16 are formed in the breathable area.

[0035] Furthermore, the non-double-layer structure area is a single-layer structure, and the single-layer structure includes warp yarns 14 and weft yarns 15, and the single-layer structure is formed by the interweaving of the warp yarns 14 and the weft yarns 15.

[0036] Furthermore, the warp yarns 14 and the weft yarns 15 are combined and woven with colored yarns and locally with transparent elastic monofilaments to form a single-layer structure.

[0037] Furthermore, the porous area is located in any area of the fabric body 1.

[0038] Furthermore, the transparent elastic monofilament is thermoplastic polyester elastomer (TPEE) or thermoplastic polyurethane elastomer (TPU).

[0039] In the double-layered leno fabric of this embodiment, a locally delaminable and separable leno layer 13 is formed on the leno fabric. The leno layer 13 can be provided with lenos 131 of the same structure, and the leno structures on the adjacent layer can be seen from either the surface layer or the bottom layer side. The structural feature of the double-layered leno fabric in this embodiment lies not only in the double layer, but also in the locally double-layered leno layer. The leno structures on these two adjacent leno layers can be flexibly set to the same or different structures, and then combined to form different fabric structures. This changes the structure of the traditional leno fabric from being only single-layered, and further optimizes the structural pattern of the locally double-layered leno fabric.

[0040] Example 2

[0041] This embodiment provides a method for preparing a double-layered leno fabric, including the following steps:

[0042] Step 1, place the woven warp beam into the corresponding knitting yarns. The weft yarns are composed of several weft accumulators, and each specification of yarn is placed in the weft accumulator in sequence according to the needs of the shoe upper pattern.

[0043] Step 2, start the loom. The loom interweaves the weft yarns with the warp yarns in a set order to form a leno pattern delaminated fabric.

[0044] Step 3, subject the fabric to high-temperature pre-shrinking and setting treatment at a setting temperature of 150°C - 180°C to make the whole fabric more flat.

[0045] Among them, the setting temperature is preferably 160°C, and can be 150°C, 170°C, 180°C, or any point value between 150°C - 180°C.

[0046] Furthermore, the knitting yarns are transparent monofilaments or polyester yarns.

[0047] Example 3

[0048] This embodiment provides a method for preparing a double-layered leno fabric, including the following steps:

[0049] Step 1, design the shoe upper, and use professional grand plan software to create an EP format file according to the relevant parameters of the shoe upper and input it into the loom. The woven warp beam is pre-loaded with transparent monofilaments or polyester yarns. The weft yarns are composed of 8 weft accumulators, and each specification of yarn is placed in the weft accumulator in sequence according to the needs of the pattern, and 8 weft yarns can be placed.

[0050] Step 2, start the loom to weave an initial product of a certain size. The weaving method is as Figure 10 shown, weaving from bottom to top. Red represents the start of the first shuttle weft yarn, green represents the start of the second shuttle weft yarn, blue represents the start of the third shuttle weft yarn, and the machine automatically interweaves the weft yarns with the warp yarns in sequence, and black represents the sinking of the weft yarn. In this version, red is polyester yarn, green is polyester yarn, and blue is TPU monofilament;

[0051] Step 3: The initial product is subjected to high-temperature pre-shrinkage and shaping treatment, with the shaping temperature being about 150 to 180 degrees to make the entire piece smoother;

[0052] Step 4: Design the film draft, cut the pieces, and then laser process the upper.

[0053] The woven double-layer tangled hole weaving process in the utility model can produce a texture with a unique tangled hole design in the double-layer fabric while ensuring the quality and stability of the fabric. The specific description is as follows:

[0054] Hollowing is a double warp beam machine, ( Figure 7 The medium-thick black is the upper warp yarn, and the thin black is the lower warp yarn);

[0055] In a single-layer structure, colored yarns can be used on both sides (such as Figure 7 ) The warp and weft yarns are interwoven relatively tightly, and transparent elastic monofilaments such as TPU, TPEE and other high-strength yarns are used locally;

[0056] Holes are made at any local position and layered. One shuttle uses transparent elastic monofilaments such as TPU, TPEE and other high-strength yarns, and uses hollow sarao weave to make a hollow hole effect on the surface layer. Other colored yarns also use hollow sarao weave to make a hollow hole effect on the bottom layer, so that the two hole shapes are superimposed and displayed;

[0057] The perforated effect is made at any local position. The perforated position is formed by the upper warp thick needle rotating and twisting the lower warp to bundle multiple weft yarns to form a perforated hole (such as Figure 9 ).

[0058] In the combination of the above three structures, a material with a width of 160CM can be woven by the machine first, and then shrunk through high-temperature finishing, local layering by warp yarn, and combined with hollow Sara structure to achieve double-layer hole changes, so that the material presents a rich pore texture.

[0059] Example 4

[0060] This embodiment provides a double-layer hole-punched fabric upper, and the upper is made of the double-layer hole-punched fabric mentioned above.

[0061] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation 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 covered by the present invention.
