Description

Technical Field

[0001] This invention relates to the field of woven fabrics, specifically to a color-changing woven fabric and its preparation process, as well as shoe uppers and shoes. Background Technology

[0002] Traditional woven shoe fabrics are mostly limited to plain weave, elasticity, three-dimensional or hollow structures, without much variation in visual layering. Therefore, to meet the needs of product development, products with color-changing effects are being developed more and more.

[0003] For example, patent CN218026566U proposed a color-changing woven fabric in June 2022. The fabric includes a weft raised strip, a first weft groove strip disposed on one side of the weft raised strip, and a second weft groove strip disposed on the other side of the weft raised strip. The height of the weft raised strip is higher than that of the first and second weft groove strips. The weaving yarn of the second weft groove strip is different from that of the first weft groove strip, or the weaving pattern of the second weft groove strip is different from that of the first weft groove strip, thereby achieving a color-changing effect.

[0004] However, the patent did not conduct further research on the breathability of the fabric. As a material used in footwear, especially for spring and summer footwear products, breathability is very important. Therefore, while ensuring the color-changing effect of the fabric, it is necessary to further study how to improve the breathability of the fabric. Summary of the Invention

[0005] In view of this, the woven fabric of the present invention breaks through the conventional products made in the past, changes the original structure, and presents a visual effect of hollowing, color illusion and rich color changes. By changing the organizational structure of the warp and weft, it presents a breathable hole and color illusion effect.

[0006] As a first aspect of the present invention, a holographic woven fabric is provided, comprising warp yarns and weft yarns, wherein the weft yarns include a first weft yarn, a second weft yarn, and a third weft yarn of different colors, and the warp yarns include a first warp yarn and a second warp yarn. The woven fabric includes a holographic region in which the first weft yarn, the second weft yarn, and the third weft yarn are sequentially distributed below the first warp yarn. The second warp yarn is wound from the front of the first warp yarn from one side to the other side and then distributed below the first weft yarn, the second weft yarn, and the third weft yarn, and then wound from the top of the first warp yarn to the other side, and so on in a cycle.

[0007] Furthermore, the number of the first warp yarns is greater than that of the second warp yarns, and the diameter of a single first warp yarn is smaller than that of a single second warp yarn.

[0008] Furthermore, the woven fabric also includes a solid color area, in which the first warp yarn, the second warp yarn, the first weft yarn, the second weft yarn, and the third weft yarn are interwoven in a plain weave, twill weave, or satin weave, and the first weft yarn and the third weft yarn are placed under the second weft yarn.

[0009] Furthermore, in the clean color area, a portion of the second weft yarn is located on the uppermost layer of the weft yarns, and another portion is located in the middle layer, while the first and third weft yarns are located on the lowermost layer of the weft yarns; the first and second warp yarns are interwoven with the first, second, and third weft yarns in a plain weave, twill weave, or satin weave pattern, and the second warp yarn is placed under the first warp yarn.

[0010] Furthermore, the woven fabric also includes a mesh area, which comprises an end and a mesh portion. At the end, the first, second, and third weft yarns are sequentially distributed above the second warp yarn. The first warp yarn wraps around the second warp yarn from one side to the other and then distributes itself above the first, second, and third weft yarns, before wrapping around it from below the second warp yarn to the other side and fixing the first, second, and third weft yarns. At the mesh portion, the first weft yarn and its adjacent preceding one or more weft yarns are distributed above the second warp yarn. The first warp yarn wraps around the second warp yarn from one side to the other and then distributes itself above the first and second weft yarns. The first warp yarn is positioned above the adjacent first or several weft yarns, then wraps around from below the second warp yarn to the other side and secures it. After securing, the second weft yarn is distributed above the second warp yarn. The first warp yarn wraps around from the back of the second warp yarn from one side to the other side and is then distributed above the second weft yarn, before wrapping around from below the second warp yarn to the other side and securing it. Similarly, the third weft yarn, with its adjacent last or several weft yarns, is distributed above the second warp yarn. The first warp yarn wraps around from the back of the second warp yarn from one side to the other side and is then distributed above the third weft yarn and its adjacent last or several weft yarns, before wrapping around from below the second warp yarn to the other side and securing it. Further, the first and second warp yarns are transparent yarns.

[0011] Furthermore, the ratio of the number of the first weft yarn, the second weft yarn, and the third weft yarn is 1:3:1 or 1:2:1.

[0012] Furthermore, the specifications of the first weft yarn, the second weft yarn, and the third weft yarn are 50~150D.

[0013] Furthermore, the first or second weft yarn includes at least two different colored yarns, and the different colored yarns are presented alternately on the surface of the fabric; or the first and second weft yarns each include at least two different colored yarns, and their respective different colored yarns are presented alternately on the surface of the fabric, thereby achieving multi-color changing.

[0014] As a second aspect of the present invention, a process for preparing a color-changing woven fabric as described above is provided, comprising the following steps: A: Design the shoe upper or fabric, and use professional macro software to create an EP format file based on relevant parameters and input it into the loom. The warp yarn head is a pre-loaded warp yarn, and the weft yarn consists of 8 weft feeders. According to the needs of the pattern, place each specification of yarn into the weft feeder in sequence. B: Start the loom and weave the initial product of the whole width. Weave from top to bottom. The machine automatically interweaves the weft yarn with the warp yarn in sequence. C: The initial product undergoes high-temperature pre-shrinking and shaping treatment at a temperature of 150-180℃ to ensure a smooth surface.

[0015] Furthermore, it also includes the following steps: D: Design the film draft, then cut the pieces, and then laser process the shoe upper.

[0016] As a third aspect of the invention, a shoe upper is provided, at least a portion of which is made of the iridescent woven fabric as described above.

[0017] As a fourth aspect of the invention, a shoe is provided, comprising an upper and a sole, wherein at least a portion of the upper is made of the iridescent woven fabric as described above.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The first and second warp yarns are wound together through different weave structures, and combined with the three-color weft yarns distributed in sequence, to form a woven fabric with a color-changing effect. The warp and weft yarns are twisted together by a heddle-type weaving machine to form obvious holes and gaps. The resulting fabric can present different color effects when viewed from both sides, with a rich sense of visual layering and vitality. The fabric is not easily deformed, has good breathability, and good stiffness.

[0019] 2. The large mesh structure formed by the difference in the distribution of the winding points of the weft yarn and the warp yarn can give the fabric better breathability; 3. The fabric of the present invention also uses plain weave, twill weave or satin weave and other plain weave structures, so that different weave structures are used in combination. On the same fabric, both iridescent colors and solid color blocks can be presented. This not only increases the variability of the whole fabric, but also makes the fabric, shoe shape and shoe surface look richer, more varied and three-dimensional.

[0020] 4. In the clean color area of ​​the fabric of the present invention, the double-layer setting of the weft yarns located on the outer layer achieves a better effect of covering the remaining colored yarns in the bottom layer, ensuring the purity of the color in the clean color area and improving the quality of the fabric.

[0022] First weft yarn 1, second weft yarn 2, third weft yarn 3, first warp yarn 4, first warp yarn 4. Detailed Implementation

[0023] The present invention will now be further described in conjunction with embodiments and accompanying drawings. Example

[0024] This embodiment proposes a holographic woven fabric, such as... Figure 1 As shown, the fabric includes warp and weft yarns. The weft yarns include a first weft yarn 1, a second weft yarn 2, and a third weft yarn 3 of different colors. The warp yarns include a first warp yarn 4 and a second warp yarn 5, with the number of first warp yarns 4 being greater than the number of first warp yarns 4. The single diameter of the first warp yarn 4 is smaller than the single diameter of the first warp yarn 4. The woven fabric includes a color-changing area. In the color-changing area, the first weft yarn 1, the second weft yarn 2, and the third weft yarn 3 are sequentially distributed below the first warp yarn 4. The first warp yarn 4 is wrapped around from the front of the first warp yarn 4 from one side to the other side and then distributed below the first weft yarn 1, the second weft yarn 2, and the third weft yarn 3. Then it is wrapped around from the top of the first warp yarn 4 to the other side, and so on in a cycle.

[0025] In this embodiment, as a preferred approach, the first warp yarn 4 is a transparent yarn, such as TPU yarn or TPEE yarn. Its transparent color can reduce interference with the color design of the shoe upper. However, this technical solution is not the only limitation. When the design requires it, the warp yarn can also be other yarns, such as polyester yarn, nylon yarn, etc., and its color can be black, white or other colored yarns.

[0026] In this embodiment, as a preferred embodiment, the ratio of the number of first warp yarns 4 to the number of first warp yarns 4 is 5:2, that is, every 5 first warp yarns 4 are paired with 2 first warp yarns 4 for weaving. However, this ratio is not the only limitation, and those skilled in the art can adjust the pairing ratio as needed.

[0027] In a preferred embodiment, the ratio of the number of the first weft yarn 1, the second weft yarn 2, and the third weft yarn 3 is 1:3:1 or 1:2:1. However, this ratio is not the only limitation, and those skilled in the art can adjust the ratio of the first weft yarn 1, the second weft yarn 2, and the third weft yarn 3 as needed to obtain the desired color-changing effect.

[0028] In this embodiment, the first warp yarn 4 and the first warp yarn 4 are wound together through different organizational structures, and are combined with three-color weft yarns distributed in sequence to form a woven fabric with a color-changing effect. The warp yarns and weft yarns are twisted together by a heddle-type weaving machine to form obvious holes and gaps. The resulting fabric can present different color effects when viewed from both sides, with a rich sense of visual layering and vitality. The fabric is not easily deformed, has good breathability, and good stiffness.

[0029] The preparation process of the iridescent woven fabric in this embodiment includes the following steps: A: Design the shoe upper or fabric, and use professional macro software to create an EP format file based on relevant parameters and input it into the loom. The warp yarn head is a pre-loaded warp yarn, and the weft yarn consists of 8 weft feeders. According to the needs of the pattern, place each specification of yarn into the weft feeder in sequence. B: Start the loom and weave the initial product of the whole width. Weave from top to bottom. The machine automatically interweaves the weft yarn with the warp yarn in sequence. C: The initial product undergoes high-temperature pre-shrinking and shaping treatment at a temperature of 150-180℃ to ensure a smooth surface.

[0030] When the fabric of this embodiment is used to make the shoe upper, it also includes D: Design the film draft, then cut the pieces, and then laser process the shoe upper.

[0031] As an extended embodiment of this example, the first weft yarn 2 includes at least two yarns of different colors, and the two different colored yarns are presented alternately on the surface of the fabric; or the second weft yarn 3 includes at least two yarns of different colors, and the two different colored yarns are presented alternately on the surface of the fabric; or both the first weft yarn 2 and the third weft yarn 3 include at least two yarns of different colors, and the two different colored yarns are presented alternately on the surface of the fabric; thereby, a multi-colored iridescent effect can be achieved from different perspectives. Example

[0032] To further enhance the richness of the fabric's structure, this woven fabric, based on Example 1, also includes a solid color area, such as... Figure 2-3As shown, in the clean color area, the first warp yarn 4, the first weft yarn 4, the first weft yarn 1, the second weft yarn 2, and the third weft yarn 3 are interwoven in a plain weave pattern, and the first weft yarn 1 and the third weft yarn 3 are placed under the second weft yarn 2.

[0033] In addition, the first warp yarn 4 is interwoven with the first weft yarn 1, the second weft yarn 2, and the third weft yarn 3 in a satin or twill weave pattern, which can be selected by those skilled in the art as needed.

[0034] In a preferred embodiment, the ratio of the number of the first weft yarn 1, the second weft yarn 2, and the third weft yarn 3 is 1:3:1 or 1:2:1, and the total diameter of the second weft yarn 2 is greater than the sum of the total diameters of the first weft yarn 1 and the second weft yarn 2, so as to ensure that the second weft yarn 2 can better cover the first weft yarn 1 and the third weft yarn 3, and ensure the purity of the outer surface color.

[0035] The fabric in this embodiment also incorporates plain weave, twill, or satin weave structures, allowing different weave structures to be used interchangeably. This allows for both iridescent and solid color blocks to be presented on the same fabric, increasing the variability of the entire fabric and making the fabric, shoe shape, and shoe surface appear richer, more varied, and more three-dimensional. Example

[0036] This embodiment is an optimized version of Embodiment 2. Considering that when the first weft yarn 1 is white or a light color, the colors of the second weft yarn 2 and the third weft yarn 3 often show through the single layer of the first weft yarn 1, resulting in an impure color on the fabric surface and affecting the fabric's quality, therefore, to make the fabric surface color purer and improve the product's quality, such as... Figure 4 As shown, in this embodiment, in the clean color area, a portion of the second weft yarn 2 is located on the top layer of the weft yarns, and another portion is located in the middle layer. The first weft yarn 1 and the third weft yarn 3 are located on the bottom layer of the weft yarns. The first warp yarn 4 and the first weft yarn 1, the second weft yarn 2, and the third weft yarn 3 are interwoven in a plain weave, twill weave, or satin weave pattern. That is, the second weft yarn 2 is woven in a double-layer pattern, which provides stronger coverage for the second weft yarn 2 and the third weft yarn 3, thereby making the color of the outer surface of the fabric cleaner.

[0037] As a preferred embodiment, the ratio of the number of the first weft yarn 1, the second weft yarn 2, and the third weft yarn 3 is 1:3:1 or 1:4:1, and the total diameter of the second weft yarn 2 is not less than 1.5-2 times the sum of the total diameters of the first weft yarn 1 and the second weft yarn 2, so as to ensure that the second weft yarn 2 can be double-layered and can better cover the first weft yarn 1 and the third weft yarn 3, and ensure the purity of the outer surface color.

[0038] In this embodiment, the double-layer arrangement of the weft yarns on the outer layer of the fabric in the solid color area better conceals the remaining colored yarns in the bottom layer, ensuring the purity of the color in the solid color area and enhancing the quality of the fabric. Example

[0039] To further improve the breathability of the fabric, the woven fabric in this embodiment, based on the aforementioned embodiments, also includes a mesh area, such as... Figure 5 As shown, the mesh area includes an end and a mesh portion. At the end, the first weft yarn 1, the second weft yarn 2, and the third weft yarn 3 are sequentially distributed above the second warp yarn 5. The first warp yarn 4, starting from behind the second warp yarn 5, wraps around from one side to the other and then distributes itself above the first weft yarn 1, the second weft yarn 2, and the third weft yarn 3. It then wraps around from below the second warp yarn 5 to the other side, fixing the first weft yarn 1, the second weft yarn 2, and the third weft yarn 3. At the mesh portion, the first weft yarn 1 and its adjacent preceding one or more weft yarns are distributed above the second warp yarn 5. The first warp yarn 4, starting from behind the second warp yarn 5, wraps around from one side to the other and then distributes itself above the first weft yarn 1 and its adjacent... The first warp yarn 4 is placed above the first warp yarn 5, then wrapped around from the back of the second warp yarn 5 to the other side and fixed. After fixing, the second warp yarn 2 is distributed above the second warp yarn 5. The first warp yarn 4 is wrapped around from the back of the second warp yarn 5 from one side to the other side and then distributed above the second warp yarn 2. Then it is wrapped around from the bottom of the second warp yarn 5 to the other side and fixed. After fixing, the third warp yarn 3 and its adjacent next one or several weft yarns are distributed above the second warp yarn 5. The first warp yarn 4 is wrapped around from the back of the second warp yarn 5 from one side to the other side and then distributed above the third warp yarn 3 and its adjacent next one or several weft yarns. Then it is wrapped around from the bottom of the second warp yarn 5 to the other side and fixed.

[0040] Alternatively, the second weft yarn may participate in the same weaving position as the first or third weft yarn, and form a mesh structure according to the weaving rules described above.

[0041] As a preferred embodiment of the above, the specifications of the first weft yarn 1, the second weft yarn 2 and the third weft yarn 3 are 50~150D. Example

[0042] This embodiment proposes a shoe upper, at least a portion of which is made of the iridescent woven fabric as described above. Example

[0043] This embodiment proposes a shoe, including an upper and a sole, wherein at least a portion of the upper is made of the iridescent woven fabric described above.

[0044] The above are merely preferred embodiments of the present invention, but do not limit the patent scope of the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features.
