Description

Technical Field

[0001] This utility model relates to the field of woven fabric manufacturing, and in particular to a dynamically color-changing fabric. Background Technology

[0002] In an era of multiculturalism and fashion development, innovative and fashionable clothing fabrics are constantly being developed. While pursuing dynamic comfort, people also seek innovative visual experiences from clothing. Traditional fabrics can only present one color effect in static and dynamic conditions, or require the addition of temperature-sensitive, pressure-sensitive, and light-sensitive materials to achieve dynamic color-changing effects, which is costly and involves complex processing techniques.

[0003] One existing color-changing fabric includes raised strips and grooved strips on both sides of the raised strips. The grooved strips on both sides of the raised strips are different colors, creating a color-changing effect when viewed from different angles. However, the weaving process of this color-changing fabric is complex, and it cannot achieve both static and dynamic color-changing effects, thus failing to meet the needs of clothing materials for visual effects of multiple colors, both static and dynamic. Utility Model Content

[0004] The purpose of this invention is to provide a dynamic color-changing fabric that can achieve different visual effects in static and dynamic states, and is low in cost and structurally stable. The specific technical solution is as follows:

[0005] A dynamic color-changing fabric includes multiple first structures and multiple second structures formed by integral weaving. The multiple first structures and multiple second structures are arranged alternately. The first structures and second structures are different colors. When the fabric is not stretched, the second structures are raised structures. The first structures are sandwiched between two adjacent second structures and the two adjacent second structures cover the first structures. The second structures are colored. When the fabric is stretched and deformed, the second structures move away from the top of the first structures, and the first and second structures are colored together, so that the fabric can present multiple colors, thereby enabling the fabric to achieve a dynamic color-changing effect.

[0006] Furthermore, the second structure includes a first structure and a second structure. The first structure is located above the second structure. The first structure includes a middle region, a first end region, and a second end region. When the fabric is not stretched, the middle region of the first structure is located directly above the second structure. The first end region and the second end region of the first structure protrude from both ends of the second structure and are respectively located above the adjacent first structures. The first end regions and the second end regions of two adjacent first structures are located above the same first structure to achieve a covering effect on the first structure.

[0007] Furthermore, when the fabric is not stretched, the length of the first structure is less than the length of the second structure, and the lengths of the first end region and the second end region of the first structure are not less than half the length of the first structure. When the fabric is fully stretched, the length of the first structure is less than the length of the second structure, and the lengths of the first structure and the second structure are basically the same.

[0008] Furthermore, it includes at least one warp yarn and at least two weft yarns, the weft yarns including a first weft yarn and a second weft yarn, the first weft yarn and the second weft yarn are different colors, in the first structure and the second structure, the first weft yarn and the second weft yarn are arranged alternately, the warp yarn and the first weft yarn are elastic yarns, and the elasticity of the warp yarn and the first weft yarn is greater than the elasticity of the second weft yarn.

[0009] Furthermore, in the second structure, the first weft yarn interweaves with the warp yarn, while the second weft yarn does not interweave with the warp yarn to form a long float. The upper floats of adjacent first weft yarns interweave with the warp yarns are misaligned, and the contraction of the first weft yarn causes the second weft yarn to arch and form a protrusion.

[0010] Furthermore, the fineness of the second weft yarn is greater than that of the first weft yarn, which allows the second structure to shrink more, thus enabling the second weft yarn to have a more obvious arching effect. After the second weft yarn arches, it covers the first weft yarn, so that the second structure only displays the color of the second weft yarn.

[0011] Furthermore, in the first structure, both the first and second weft yarns are tightly interwoven with the warp yarns, and the upper floating point of the interweaving of the first weft yarn and the warp yarn is staggered with the upper floating point of the interweaving of the second weft yarn and the warp yarn to form a multi-color mixed effect.

[0012] Furthermore, the warp includes a first warp and a second warp. The color or dyeing properties of the second warp are different from those of the first warp. The second warp participates in the interweaving of a part of the first structure, and the first warp participates in the interweaving of another part of the first structure, so that the fabric exhibits a more diverse dynamic color-changing effect when stretched and deformed.

[0013] Furthermore, the first warp yarn is 75D / 72F polyester yarn with 40D spandex and the second warp yarn is 75D / 72F polyester yarn with 40D spandex.

[0014] Furthermore, the first weft yarn is 75D / 72F polyester loose-wrapped 40D spandex yarn, and the second weft yarn is 150D / 144F polyester DTY.

[0015] The dynamic color-changing fabric of this invention comprises a first structure and a second structure formed by integrally weaving at least one warp yarn and at least two weft yarns. The first and second structures are of different colors. When the fabric is not stretched, the second structure is a raised structure, covering the first structure, and only the second structure is colored on the fabric surface. When the fabric is stretched and deformed, the second structure unfolds, moving away from the top of the first structure, and the fabric surface is colored by both the first and second structures, thus achieving a dynamic color-changing effect. This dynamic color-changing fabric achieves a dynamic color-changing effect without the need for temperature-sensitive, pressure-sensitive, or light-sensitive materials, resulting in low cost and high production efficiency.

[0020] To better understand the purpose, structure, and function of this utility model, the dynamic color-changing fabric of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown, the dynamic color-changing fabric of this invention includes multiple first weave structures 1 and multiple second weave structures 2 integrally woven together. The first weave structures 1 and the multiple second weave structures 2 are spaced apart along the weft direction, and the first weave structures 1 and the second weave structures 2 are of different colors. When the fabric is not stretched, the second weave structures 2 are raised structures, with a first weave structure 1 sandwiched between two adjacent second weave structures 2, and two adjacent second weave structures 2 covering the first weave structures 1; only the second weave structures 2 are colored. When the fabric is stretched and deformed, the second weave structures 2 move away from the top of the first weave structures 1, and both the first weave structures 1 and the second weave structures 2 are colored together, allowing the fabric to display multiple colors, thus achieving a dynamic color-changing effect.

[0022] Furthermore, the second organization 2 includes a first structure 21 and a second structure 22, with the first structure 21 located above the second structure 22. The first structure 21 includes a middle region 211, a first end region 212, and a second end region 213.

[0023] like Figure 1As shown, when the fabric is not stretched, the middle region 211 of the first structure 21 is located directly above the second structure 22. The first end region 212 and the second end region 213 of the first structure 21 protrude from the second structure 22 and are respectively located above the adjacent first tissue 1. Furthermore, the first end region 211 and the second end region 212 of two adjacent first structures 21 are located on the same first tissue 1 to achieve a covering effect on the first tissue 1.

[0024] Preferably, in this state, the length of the first weave 1 is less than the length of the second structure 22 in the second weave 2, and the lengths of the first end region 211 and the second end region 212 of the second structure 21 in the second weave 2 are both not less than half the length of the first weave 1, to ensure that the first end region 211 and the second end region 212 of the two adjacent first structures 21 fully cover the first weave 1, thereby making the fabric in this state only show the color of the second weave 2. Here, "length" refers to the length of the first weave 1 and the second weave 2 in the weft direction.

[0025] like Figure 2 As shown, when the fabric is stretched and deformed, the second structure 2 unfolds, and both the first structure 21 and the second structure 22 in the second structure 2 are stretched and deformed. The first end region 211 and the second end region 212 of the two adjacent first structures 21 move away from the top of the first structure 1, so that the first structure 1 is presented on the fabric, and the first structure 1 and the second structure 2 are displayed together. At this time, the fabric displays multiple colors.

[0026] Preferably, when the fabric is fully stretched, the length of the first structure 1 is less than the length of the second structure 22, and the lengths of the first structure 21 and the second structure 22 are substantially the same, so that the first structure 1 can be fully exposed on the fabric surface, thereby improving the color rendering effect of the first structure 1. The term "fully stretched" refers to the fabric's structure being stretched to its maximum extent without damage; "substantially the same length" includes both cases where the lengths of the first structure 21 and the second structure 22 are exactly the same, and cases where there is a slight difference in length between the first structure 21 and the second structure 22. It is understood that, due to the fabric's soft and elastic nature, as long as the lengths of the first structure 21 and the second structure 22 are substantially the same, the technical effect of fully exposing the first structure 1 on the fabric surface can be achieved.

[0027] Furthermore, the first structure 1 can be multi-colored, and the second structure 2 can be monochromatic, so that the fabric appears monochromatic when it is not stretched, and when the fabric is stretched and deformed, the first structure 1 and the second structure 2 together display colors, and the fabric displays more colors to enhance the overall dynamic color saturation of the fabric.

[0028] The dynamically color-changing fabric of this invention includes at least one warp yarn and at least two weft yarns. The warp yarn is an elastic yarn, and the at least two weft yarns are a first weft yarn 41 and a second weft yarn 42. The first weft yarn 41 and the second weft yarn 42 have different colors and elasticities, and the elasticity of the warp yarn and the first weft yarn 41 is greater than that of the second weft yarn 42. Preferably, the first weft yarn 41 is an elastic yarn, and the second weft yarn 42 is a regular yarn.

[0029] Furthermore, at least one of the warp yarns is a first warp yarn 31, which is an elastic yarn. The elasticity of the first warp yarn 31 is similar to that of the first weft yarn 41, and the elasticity of the first warp yarn 31 is greater than that of the second weft yarn 42.

[0030] Furthermore, the first warp yarn 31 may be selected as a yarn with the same color and / or elasticity as the first weft yarn 41.

[0031] The following is a yarn selection for the dynamic color-changing fabric of this utility model:

[0032] First warp yarn 31: 75D / 72F polyester empty-wrapped 40D spandex yarn.

[0033] First weft yarn 41: 75D / 72F polyester empty-wrapped 40D spandex yarn.

[0034] Second weft yarn 42: 150D / 144F polyester DTY.

[0035] Yarns with spandex coating have greater elasticity than yarns without spandex coating. The denier (D) number represents the fineness; the higher the D number, the coarser the yarn.

[0036] Figure 3 In the middle, the horizontal direction is the weft yarn and the vertical direction is the warp yarn. Warp yarns 1-12 participate in the weaving process of the second structure 2, and warp yarns 13-18 participate in the weaving process of the first structure 1.

[0037] like Figure 3 and 4 As shown, taking the first warp yarn 31 as an example of interlacing, in the second structure 2, the weaving method of the warp and weft yarns is as follows: the first weft yarn 41 is tightly interlaced with the first warp yarn 31, and the second weft yarn 42 is not interlaced with the first warp yarn 31 to form long floats. The first weft yarn 41, the second weft yarn 42, and the first warp yarn 31 are continuously woven in the above-mentioned weaving method.

[0038] Furthermore, in the second structure 2, the first weft yarn 41 and the second weft yarn 42 are arranged alternately, and the floating points of adjacent first weft yarns 41 interlacing with the first warp yarns 31 are staggered to ensure the stability of the fabric structure.

[0039] Furthermore, the elasticity of the first weft yarn 41 is greater than that of the second weft yarn 42. The contraction of the first weft yarn 41 causes the second weft yarn 42 to arch, forming a protrusion. Furthermore, the fineness of the second weft yarn 42 is greater than that of the first weft yarn 41, allowing for a greater degree of contraction in the second structure 2, thus enabling the second weft yarn 42 to have a more pronounced arching effect. After arching, the second weft yarn 42 covers the first weft yarn 41, ensuring that the second structure 2 only displays the color of the second weft yarn 42.

[0040] In the first structure 1, the weaving method of the warp and weft yarns is as follows: the first weft yarn 41 and the first warp yarn 31 are tightly interwoven, the second weft yarn 42 and the first warp yarn 31 are tightly interwoven, and the upper floating point of the interweaving of the first weft yarn 41 and the first warp yarn 31 is misaligned with the upper floating point of the interweaving of the second weft yarn 42 and the first warp yarn 31. The yarns shrink to form a compact, multi-colored mixed structure 1. That is, the first structure 1 is a mixture of multiple colors of the first warp yarn 31, the first weft yarn 41 and the second weft yarn 42.

[0041] Furthermore, in the first organization 1, the first weft yarn 41 and the second weft yarn 42 are also arranged at intervals.

[0042] Furthermore, multiple first weft threads 1 and multiple second weft threads 2 are spaced apart. When the fabric is not stretched, two adjacent protrusions of the second weft threads 2 can cover the first weft threads 1. At this time, the first weft threads 1 do not show color on the fabric surface, and the fabric surface only shows the yarn color of the second weft yarn 42. When the second weft yarn 42 is a single color, the fabric has a single color effect. When the fabric is stretched, since the second weft threads 2 are stretched to be flat, the first weft threads 1 can be shown on the fabric surface. At this time, both the first weft threads 1 and the second weft threads 2 show color on the fabric surface, giving the fabric a multi-color mixed effect.

[0043] Furthermore, the fabric may also include a second warp yarn, the color or dyeing properties of which differ from the first warp yarn 31. In multiple first weaves 1, a portion of the first weave 1 is woven with the second warp yarn, while another portion is woven with the first warp yarn 31, so that the fabric can exhibit more color mixing effects when stretched and deformed, enhancing the fabric's color saturation. Furthermore, the second warp yarn can also be selected from 75D / 72F polyester loose-lying 40D spandex yarn.

[0044] In the first organization 1 mentioned above, the first weft yarn 41 is tightly interwoven with the second warp yarn, and the second weft yarn 42 is tightly interwoven with the second warp yarn. The upper floating point of the interweaving of the first weft yarn 41 and the second warp yarn is misaligned with the upper floating point of the interweaving of the second weft yarn 42 and the second warp yarn, forming a tight single-layer fabric structure, so as to enrich the dynamic color-changing effect of the fabric while ensuring the stability of the fabric structure.

[0045] In the preferred embodiment described above, the arrangement of multiple first weft structures 1 and multiple second weft structures 2 spaced apart along the weft direction facilitates the implementation of yarn weaving processes, is applicable to general shuttle looms, and results in lower costs, simpler processes, and higher production efficiency when using ordinary looms. Furthermore, the multiple first weft structures 1 and multiple second weft structures 2 can also be spaced apart along the warp direction.

[0046] In summary, the dynamic color-changing fabric of this invention includes a first structure 1 and a second structure 2 formed by integrally weaving at least one warp yarn and at least two weft yarns. The first structure 1 and the second structure 2 are different colors. When the fabric is not stretched, the second structure 2 is a raised structure, covering the first structure 1, and only the second structure 2 is colored on the fabric surface. When the fabric is stretched and deformed, the second structure 2 unfolds, moving away from the top of the first structure 1, and the fabric surface is colored by both the first structure 1 and the second structure 2, thus achieving a dynamic color-changing effect. The dynamic color-changing fabric of this invention can achieve a dynamic color-changing effect without adding temperature-sensitive, pressure-sensitive, or light-sensitive materials, resulting in low cost and high production efficiency.
