[0006] Furthermore, the second warp yarn is a transparent yarn; the inner layer also includes a plurality of third weft yarns arranged sequentially along the warp direction and each having a color; the color of the third weft yarn is different from the color of the second weft yarn, and it is interlaced with the second weft yarn and floats on the second warp yarn; the shrinkage rate of the third weft yarn is greater than the shrinkage rate of the first yarn.

[0007] Furthermore, in each of the weft yarn groups, the second weft yarn is divided into a first color yarn group and a second color yarn group arranged sequentially along the same direction of the warp; the first color yarn group includes a plurality of first color yarns arranged sequentially along the warp; the second color yarn group includes a plurality of second color yarns arranged sequentially along the warp; the first color yarn and the second color yarn both have colors and the colors are different.

[0008] Furthermore, the colors of the first colored yarn, the second colored yarn, the third weft yarn, and the first yarn are green, red, white, and black, respectively.

[0009] Furthermore, the connecting layer also includes a plurality of second yarns that are arranged sequentially along the warp direction and are all transparent; each second yarn corresponds one-to-one with each first yarn and is combined into a single strand for common threading; the shrinkage rate of the second yarn is less than the shrinkage rate of the first weft yarn and the second weft yarn.

[0010] Furthermore, the first yarn interweaves with the first warp yarn in a plain weave manner when passing through the area where the second weft yarn floats above the second warp yarn.

[0011] Furthermore, at least one of the first weft yarn, the second weft yarn, and the first yarn is elastic.

[0012] Furthermore, the number of second warp yarns that the second weft yarn crosses each time is 3-10.

[0013] Furthermore, the first weft yarn is a transparent elastic yarn; the transparent elastic yarn is selected from TPU or TPEE.

[0014] Furthermore, the first colored yarn, the second colored yarn, and the first yarn are all polyester high-elastic yarns.

[0015] Furthermore, the third weft yarn is an elastic yarn.

[0016] This technical solution also provides a method for preparing the woven fabric as described above, comprising the following steps: designing the fabric weaving method and setting parameters; creating an EP format file of the set parameters using weaving software and inputting it into the loom; using the same transparent yarn for the first warp and the second warp; weaving the transparent yarn used for the first warp and the second warp into warp heads and installing them on the loom; the loom includes eight weft feeders; placing the first weft yarn, the first yarn, and the second weft yarn in the corresponding weft feeders according to the pattern design; starting the loom and weaving according to a preset program; pre-shrinking and setting the woven fabric at a high temperature of 150-180℃ to obtain the woven fabric.

[0017] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the woven fabric provided by this technical solution, each second weft yarn in the inner layer is woven with the second warp yarn in a floating and sinking pattern that spans at least two second warp yarns each time. The second weft yarns of adjacent weft yarn groups are woven with the second warp yarns in the opposite floating and sinking pattern along the weft direction. That is, if the second weft yarn of one of two adjacent weft yarn groups is woven with the second warp yarn in a "floating-sinking-floating-sinking..." pattern along the weft direction, then the second weft yarn of the other group is woven with the second warp yarn in a "sinking-floating-sinking-floating..." pattern along the weft direction. Therefore, the inner layer presents a grid pattern that is alternately distributed along the warp and weft directions. The grid types include grids with the second warp yarn on top and grids with the second weft yarn on top. In the connecting layer, the first yarn connects to the surface or inner layer in a serpentine pattern according to the floating / sinking of the second weft yarn relative to the second warp yarn. The heat shrinkage rate of the second yarn is less than that of the first and second weft yarns. Therefore, after the woven fabric is high-temperature set, the shrinkage of the second yarn is small, and it supports the surface and inner layers, creating a gap between them. This gives the woven fabric a good three-dimensional effect and a certain degree of elasticity. Furthermore, since the number of first warp yarns interwoven with the second yarn and the number of sinking second warp yarns are both greater than or equal to two, the woven fabric exhibits a good three-dimensional effect. Therefore, the second yarn can form holes of a certain width along the weft direction. These holes are located in the grid area where the second weft yarn floats above the second warp yarn. Thus, when observing the woven fabric from both sides along the weft direction, one can observe both the first yarn on the surface layer and a portion of the second weft yarn below the holes and floating above the second warp yarn. Since the color of the first yarn differs from that of the second weft yarn, the woven fabric exhibits richer color gradations and a stronger sense of depth, providing a pleasant visual experience. Furthermore, the fact that the first yarn passes through the inner layer from the surface layer causes its color to cyclically change from dark to light, then disappear, and then dark again along the weft direction, further enhancing the color gradations of the woven fabric and providing a richer visual experience.

[0019] 2. In the inner layer, the second warp yarn is transparent. When the second weft yarn sinks below the second warp yarn, it is covered by a colored third weft yarn. The third weft yarn provides more comprehensive coverage of the second weft yarn, resulting in purer colors in the two grid patterns formed in the inner layer, leading to a better aesthetic effect. This also strengthens the overall structural strength of the woven fabric, improving its abrasion resistance and lifespan. Specifically, the third weft yarn interweaves with the second weft yarn, rising above the second warp yarn. That is, along the weft direction, when the third weft yarn passes the second weft yarn and rises above the second warp yarn, it sinks accordingly. When the third weft yarn passes the second weft yarn and sinks below the second warp yarn, the second weft yarn... The three weft yarns rise above the second warp yarns, so the inner layer still presents an alternating grid pattern. The grid types at this time include two different and pure grids, one presented when the second weft yarn is on top of the second warp yarn and the other presented when the third weft yarn is on top of the second warp yarn. Based on this structure, when the woven fabric is observed along both sides of the weft direction, the colors observed change in units of the color of the third weft yarn, the local color of the second weft yarn below the holes, and the color of the first yarn above the holes. The sense of layering is stronger, breaking the limitation of the single sense of color layering in traditional fabrics. The visual impact brought by the color changes is also stronger, and it perfectly meets the aesthetic needs of modern people.

[0020] 3. In each weft yarn group, the second weft yarn is divided into a first color yarn group and a second color yarn group. The color of the first color yarn in the first color yarn group is different from the color in the second color yarn group. Thus, when the woven fabric is observed from both sides along the weft direction, the colors of the second weft yarns located below the holes are different. When the woven fabric is observed from the top, the grid corresponding to the second weft yarn located above the second warp yarn can also be faintly observed to show two different colors arranged along the warp direction. This achieves the purpose of further enhancing the aesthetics of the fabric and people's visual experience.

[0021] 4. The colors of the first yarn, the second yarn, the third weft yarn, and the first yarn are green, red, white, and black, respectively. The color combination is reasonable and beautiful, and is more likely to meet people's aesthetic standards.

[0022] 5. The connecting layer also includes a second yarn laid along the warp direction. The inclusion of the second yarn helps to improve the connection strength of the connecting layer. Since the second yarn is transparent, it will not damage the desired color effect and color gradation. The shrinkage rate of the second yarn is less than that of the first and second weft yarns, ensuring the formation of the perforated effect.

[0023] 6. When the first yarn passes through the area where the second weft yarn floats above the second warp yarn, it interweaves with the first warp yarn in a plain weave manner. The interweaving method is simple, easy to implement, and cost-effective.

[0024] 7. At least one of the first weft yarn, the second weft yarn, and the first yarn is elastic, which helps to improve the elasticity of the woven fabric and make the products made from it more comfortable.

[0025] 8. The number of second warp yarns that the second weft yarn crosses each time is 3-10. Therefore, the grid effect presented in the inner layer is more obvious, and the hole effect formed by the connecting layer is also more obvious. The woven fabric can also obtain a better three-dimensional effect, layering and aesthetic effect.

[0026] 9. The first weft yarn is made of transparent elastic yarn, the first colored yarn, the second colored yarn and the first yarn are all polyester high elastic yarn, and the third weft yarn is elastic yarn. Therefore, this woven fabric has excellent elasticity.

[0027] 10. The method for preparing the above-mentioned woven fabrics provided by this technical solution is relatively simple and easy to implement, with great potential for productization and high efficiency. Attached Figure Description

[0040] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0041] See Figures 1 to 3 , Figures 1 to 3 The woven fabric of this embodiment is shown. For example... Figures 1 to 3 As shown, the woven fabric provided in this embodiment includes a face layer 1, an inner layer 2, and a connecting layer 3. Both the face layer 1 and the inner layer 2 are warp and weft woven structures, meaning they are both woven from warp and weft yarns. The connecting layer 3 is used to connect the face layer 1 and the inner layer 2.

[0042] Specifically, such as Figure 1 and Figure 2As shown, the surface layer 1 includes a plurality of first warp yarns 11 and a plurality of first weft yarns 12; both the first warp yarns 11 and the first weft yarns 12 are transparent yarns; each first warp yarn 11 is arranged sequentially along the weft direction, and each first weft yarn 12 is arranged sequentially along the warp direction. The first warp yarns 11 and the first weft yarns 12 are woven using, but not limited to, plain weave, twill weave, and satin weave. In this embodiment, the first warp yarns 11 and the first weft yarns 12 are specifically woven using a plain weave, wherein the first weft yarn 12 is specifically made of transparent elastic yarn. The transparent elastic yarn is selected from TPU and TPEE, which are low in cost, have good yarn strength, and can give the woven fabric good elasticity. In addition, the first weft yarn 12 is elastic, which is beneficial to improving the elasticity of the woven fabric and ensuring that the product made from the woven fabric has good wearing comfort. It is worth noting that, based on the basic knowledge of textiles, the warp yarns involved in this application should be understood as yarns extending along the weft direction and yarns extending along the warp direction, respectively.

[0043] like Figure 1 and Figure 3 As shown, the inner layer 2 includes several second warp yarns 21, several second weft yarns 22, and several third weft yarns 23.

[0044] The second warp yarn 21 is made of transparent yarn, and each second warp yarn 21 is arranged sequentially along the weft direction.

[0045] Each second weft yarn 22 is colored. In this embodiment, each second weft yarn 22 is divided into several weft yarn groups 220 arranged sequentially along the warp direction. Each weft yarn group 220 includes several second weft yarns 22 arranged sequentially along the warp direction. In the same weft yarn group 220, each second weft yarn 22 is woven with the second warp yarns 21 in a floating and sinking pattern that spans at least two second warp yarns 21 each time. The second weft yarns 22 of two adjacent weft yarn groups 220 are woven with the second warp yarns 21 in opposite floating and sinking patterns. That is, if the second weft yarn 22 of one of two adjacent weft yarn groups 220 is woven with the second warp yarn 21 in a "float-sink-float-sink..." pattern along the weft direction, then the second weft yarn 22 of the other is woven with the second warp yarn 21 in a "sink-float-sink-float..." pattern along the weft direction. Therefore, the inner layer 2 presents a grid pattern that alternates between the warp and weft directions. The grid types include grids with the second warp yarn 21 on top and grids with the second weft yarn 22 on top. It should be understood that, in this embodiment, the number of second warp yarns 21 that each first weft yarn 12 in the same weft yarn group 220 crosses when it floats or sinks under the second warp yarn 21 should be interpreted as consistent.

[0046] Specifically, in this embodiment, the number of second weft yarns 22 crossing the second warp yarns 21 each time can be selected as 3-10. Therefore, the grid effect presented by the inner layer 2 is more obvious, the hole effect formed by the connecting layer 3 is also more obvious, and the woven fabric can obtain a better three-dimensionality, layering and aesthetic effect. In a preferred example, the number of second warp yarns 21 that each second weft yarn 22 crosses when it floats above the second warp yarn 21 is equal to the number of second warp yarns 21 that each second weft yarn 22 crosses when it sinks below the second warp yarn 21. In this way, the pattern of the inner layer 2 is more regular and the aesthetics are higher. In this embodiment, in each weft yarn group 220, the second weft yarn 22 is divided into a first color yarn group and a second color yarn group arranged sequentially along the same direction in the warp direction; the first color yarn group includes a plurality of first color yarns 221 arranged sequentially along the warp direction; the second color yarn group includes a plurality of second color yarns 222 arranged sequentially along the radial direction; the first color yarns 221 and the second color yarns 222 are both colored and different in color. Specifically, in this embodiment, the first color yarns 221 and the second color yarns 222 are both made of polyester high-elastic yarn, and the colors of the first color yarns 221 and the second color yarns 222 are green and red, respectively. Based on this structural characteristic, the pattern of the inner layer 2 is a red and green stripe pattern arranged along the warp direction. In this case, when the second warp yarn 21 floats in the grid of the first color yarns 221 and the second color yarns 222, due to the obstruction of the second warp yarn 21, the brightness of the red and green stripes is weaker than the red and green stripes of other first color yarns 221 and the second color yarns 222 that float in the grid of the second warp yarn 21.

[0047] Each third weft yarn 23 is arranged sequentially along the warp direction and is also colored. The color of the third weft yarn 23 is different from the color of the second weft yarn 22; that is, the color of the third weft yarn 23 is different from the colors of the first colored yarn 221 and the second colored yarn 222. Specifically, in this embodiment, the third weft yarn 23 is made of elastic yarn and is white. The third weft yarn 23 and the second weft yarn 22 alternately float and sink on the second warp yarn 21. That is, along the weft direction, when the third weft yarn 23 passes the second weft yarn 22 and floats on the second warp yarn 21, the third weft yarn 23 sinks on the second warp yarn 21 accordingly, and when the third weft yarn 23 passes the second weft yarn 22 and sinks on the second warp yarn 21, the third weft yarn 23 floats on the second warp yarn 21 accordingly. Thus, the inner layer 2 still presents an alternating grid pattern, and the grid type at this time includes the second weft yarn 22 on the second warp yarn 21. The two different and pure color grids presented when the third weft yarn 23 is on top of the second warp yarn 21 are covered by the colored third weft yarn 23 when the second weft yarn sinks to the second warp yarn 21. The third weft yarn 23 on top covers the second weft yarn 22 more comprehensively. Therefore, the two grids formed in the inner layer 2 are purer in color, and the aesthetic effect is better. In addition, it also strengthens the overall structural strength of the woven fabric to a certain extent and helps to improve the wear resistance and service life of the fabric.

[0048] like Figure 1 As shown, the connecting layer 3 includes a first yarn 31 and a second yarn 32.

[0049] The first yarn 31 is arranged sequentially along the warp direction and has a number of first yarns 31 of a different color than the second weft yarn 22. At least one of the first weft yarn 12, the second weft yarn 22 and the first yarn 31 is elastic to improve the elasticity of the woven fabric and make the products made from it more comfortable.

[0050] Specifically, each first yarn 31 is made of high-elastic polyester yarn, which is black in color and extends along the weft direction. When it passes through the area where the second weft yarn 22 floats above the second warp yarn 21, it interweaves with a first number of first warp yarns 11. When it passes through the area where the second weft yarn 22 sinks below the second warp yarn 21, it sinks below a second number of second warp yarns 21. The first number is greater than or equal to two and less than or equal to the number of second warp yarns 21 sinking below the second weft yarn 22 in the corresponding area. The second number is greater than or equal to two and less than or equal to the number of second warp yarns 21 floating above the second weft yarn 22 in the corresponding area. The heat shrinkage rate of the first yarn 31 is less than the heat shrinkage rate of the first colored yarn 221, the second colored yarn 222, and the third weft yarn 23 in the first weft yarn 12 and the second weft yarn 22. In this embodiment, the first yarn 31 is connected to the surface layer 1 or the inner layer 2 in a serpentine pattern according to the floating and sinking of the second yarn 32 relative to the second warp yarn 21. Since the heat shrinkage rate of the second yarn 32 is less than that of the first weft yarn 12 and the second weft yarn 22, the shrinkage of the second yarn 32 is small after the woven fabric is subsequently high-temperature set, and it can be supported between the first weft yarn 12 and the second weft yarn 22, thereby forming a gap between the surface layer 1 and the inner layer 2, so that the woven fabric has a good three-dimensional effect and gives the woven fabric a certain elasticity. Furthermore, since the number of interlaced first warp yarns 11 and the number of sunken second warp yarns 21 are greater than or equal to two, the second yarn 32 can form a hole of a certain width along the weft direction. This hole is located in the grid area where the second weft yarn 22 floats relative to the second warp yarn 21. Thus, when observing the woven fabric from both ends along the weft direction, one can observe both the first yarn 31 located on the surface layer 1 and a portion of the second weft yarn 22 located below the hole and floating above the second warp yarn 21. Since the color of the first yarn 31 is different from the color of the second weft yarn 22, the woven fabric can exhibit a richer color gradation and a greater sense of depth. The fabric is strong and provides a pleasant and unique visual experience. Furthermore, since the color of the third weft yarn 23 differs from the colors of the second weft yarn 22 and the first yarn 31, when people observe the woven fabric along both sides of the weft direction, the most intuitive feeling is that the color of the woven fabric changes in units of the color of the third weft yarn 23, the partial color of the second weft yarn 22 below the holes, and the color of the first yarn 31 above the holes. The woven fabric exhibits a clear sense of layering, breaking the limitation of the single color layering of traditional fabrics. The visual impact of the color changes is also stronger, perfectly satisfying the aesthetic needs of modern people. In addition, because the first yarn 31 passes through the inner layer 2 from the outer layer 1, the color of the first yarn 31 exhibits a cyclical change along the weft direction from the outer layer 1 to the inner layer 2, from light to light to disappear, and then from light to dark again. This further enhances the color layering of the woven fabric and provides a richer visual experience.

[0051] Furthermore, since the second weft yarn 22 is divided into a first color yarn group and a second color yarn group, and the color of the first color yarn 221 in the first color yarn group is different from the color in the second color yarn group, when people observe the woven fabric from both sides along the weft direction, the color of the second weft yarn 22 located below the holes will be different in different directions, resulting in a better visual experience. Specifically, as shown... Figure 4 As shown, the darker portion at the top of section A is represented by the black color of the first yarn 31 located above the hole, while the lighter portion at the bottom is represented by the green color of the first yarn 221 located below the hole; as shown... Figure 5 As shown, the darker portion at the top of section A is black, represented by the first yarn 31 located above the holes, while the lighter portion at the bottom is red, represented by the second yarn 222 located below the holes. Furthermore, when observing the woven fabric from above, one can faintly observe that the grid corresponding to the second weft yarn 22 above the second warp yarn 21 displays two different colors along the warp direction, thus further enhancing the fabric's aesthetics and visual appeal.

[0052] Preferably, in this embodiment, the first yarn 31 interweaves with the first warp yarn 11 in a plain weave manner when passing through the area where the second weft yarn 22 floats above the second warp yarn 21. This interweaving method is simple, easy to implement, and cost-effective. Furthermore, in this embodiment, since the first weft yarn 12 is a transparent elastic yarn, and the first colored yarn 221, the second colored yarn 222, and the first yarn 31 are all high-elastic polyester yarns, and the third weft yarn 23 is an elastic yarn, the woven fabric has excellent elasticity. The colors of the first colored yarn 221, the second colored yarn 222, the third weft yarn 23, and the first yarn 31 are green, red, white, and black, respectively, resulting in a reasonable and attractive color scheme that easily appeals to people's aesthetic preferences.

[0053] The second yarns 32 are arranged sequentially along the warp direction and are all transparent; each second yarn 32 corresponds one-to-one with each first yarn 31 and they are combined into a single strand; the shrinkage rate of the second yarn 32 is less than that of the first weft yarn 12, the second weft yarn 22, and the third weft yarn 23. The arrangement of the second yarns 32 helps to improve the connection strength of the connecting layer 3, and because the second yarns 32 are transparent, they will not damage the desired color effect and color gradation. Furthermore, because the shrinkage rate of the second yarns 32 is less than that of the first weft yarns 12, the second weft yarn 22, and the third weft yarn 23, they can work with the first yarns 31 to form a perforated effect.

[0054] The present invention also provides a method for preparing the above-mentioned woven fabric, which includes the following steps:

[0055] Design the fabric weaving method and set the parameters. Then, use the weaving software to create an EP format file of the set parameters and input it into the loom.

[0056] The first warp 11 and the second warp 21 use the same transparent yarn. The transparent yarn used by the first warp 11 and the second warp 21 is woven into a warp head and installed on the shuttle loom.

[0057] The loom includes eight weft feeders; the first weft yarn 12, the first yarn 31, and the second weft yarn 22 are placed in the corresponding weft feeders according to the pattern design. Specifically, the loom includes a first weft feeder, a second weft feeder, a third weft feeder, a fourth weft feeder, a fifth weft feeder, a sixth weft feeder, a seventh weft feeder, and an eighth weft feeder; the first weft yarn 12 is placed in the first weft feeder, the third weft yarn 23 is placed in the second weft feeder, the first colored yarn 221 is placed in the third weft feeder, the first yarn 31 is placed in the fourth weft feeder, the second yarn 32 is placed in the fifth weft feeder, and the second colored yarn 222 is placed in the sixth weft feeder.

[0058] Start the shuttle loom and begin weaving according to the preset program;

[0059] The woven fabric is pre-shrinked and set at a high temperature of 150-180℃ to obtain a woven fabric.
