Description

Technical Field

[0001] This utility model relates to the field of fabrics, and more specifically, to a breathable fabric. Background Technology

[0002] Traditional breathable fabrics rely heavily on woven eyelets, but the design of the eyelets makes the weave at the eyelets looser while the rest of the weave is tighter. As a result, the overall strength of the fabric is uneven, especially at the eyelets where the strength is greatly reduced. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a breathable fabric. The fabric is formed by interlacing warp and weft yarns to create a first region, a second region, and a third region. The fabric has different degrees of concavity and different thicknesses in the multiple regions, with the thinnest part being the lowest concavity. The lowest concavity replaces the perforated structure, and the area of ​​the lowest concavity is larger than the area of ​​the perforations, thereby maintaining the breathability of the fabric. Furthermore, the design without perforations maintains the integrity of the fabric, improves its strength, and prevents deformation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a breathable fabric, comprising a first region, a second region, and a third region, wherein the first region and the second region are arranged alternately along the length of the fabric, and the third region is located between the first region and the second region along the length of the fabric. Each second region includes two support areas and an inner region, and the inner region is located in the middle of the two support areas. The first region is lower than the support areas, and the inner region is lower than the support areas.

[0005] The present invention is further configured such that the height difference H2 between the internal area and the support area is greater than the height difference H1 between the first area and the support area.

[0006] The present invention is further configured such that the thickness D3 of the support region is greater than the thickness D2 of the first region, and the thickness D2 of the first region is greater than the thickness D1 of the inner region.

[0007] The present invention is further configured such that the third region is higher than the first region and the internal region.

[0008] The present invention is further configured such that the width of the support area is half that of the inner area, and the width of the first area is twice that of the inner area.

[0009] The present invention is further configured such that the fabric has a weave cycle of 64 warp yarns and 120 weft yarns, 32 warp yarns and 48 weft yarns interwoven to form the first region, 8 warp yarns and 48 weft yarns interwoven to form the support region, 16 warp yarns and 48 weft yarns interwoven to form the inner region, and 64 warp yarns and 12 weft yarns interwoven to form the third region.

[0010] The present invention is further configured such that, within the range of the 1st to 60th weft yarns, the 1st to 32nd warp yarns and the 1st to 48th weft yarns interweave to form the first region, the 33rd to 40th warp yarns and the 1st to 48th weft yarns, as well as the 57th to 64th warp yarns and the 1st to 48th weft yarns, interweave to form the support region, the 41st to 56th warp yarns and the 1st to 48th weft yarns interweave to form the inner region, and the 1st to 64th warp yarns and the 49th to 60th weft yarns interweave to form the third region.

[0011] The present invention is further configured such that, within the range of the 61st to 120th weft yarns, the 1st to 8th warp yarns interweave with the 61st to 108th weft yarns and the 25th to 32nd warp yarns interweave with the 61st to 108th weft yarns to form the support area; the 9th to 24th warp yarns interweave with the 61st to 108th weft yarns to form the inner area; the 33rd to 64th warp yarns interweave with the 61st to 108th weft yarns to form the first region; and the 1st to 64th warp yarns interweave with the 109th to 120th weft yarns to form the third region.

[0012] In summary, this utility model has the following beneficial effects:

[0013] The fabric is divided into three zones by interlacing warp and weft yarns. These zones create different degrees of indentation and varying thicknesses, with the lowest point being the thinnest. By replacing the perforated structure with the lowest point of indentation, the thinnest area is larger than the perforated area, ensuring the fabric's breathability. At the same time, the absence of perforations maintains the fabric's integrity, thereby increasing its strength and preventing deformation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 — Figure 4 As shown, this embodiment discloses a breathable fabric. The fabric has a weave of 64 warp yarns and 120 weft yarns in one weave cycle. In one weave cycle, warp yarns 1-32 and weft yarns 1-48 interweave to form a first region 1, warp yarns 33-64 and weft yarns 1-48 interweave to form a second region 2, warp yarns 1-64 and weft yarns 49-60 interweave to form a third region 3, warp yarns 1-32 and weft yarns 61-108 interweave to form the second region 2, warp yarns 33-64 and weft yarns 61-108 interweave to form the first region 1, and warp yarns 1-64 and weft yarns 109-120 interweave to form the third region 3. Therefore, the fabric includes a first region 1, a second region 2, and a third region 3. Furthermore, 32 warp yarns and 48 weft yarns interweave to form the first region 1, 8 warp yarns and 48 weft yarns interweave to form a support region 21, and 16 warp yarns and 48 weft yarns interweave to form a support region 21. The inner zone 22 is formed by the interweaving of yarns. The third zone 3 is formed by the interweaving of 64 warp yarns and 12 weft yarns. Because the warp yarns of the first zone 1 and the second zone 2 are arranged alternately in a cycle of 32 warp yarns, the first zone 1 and the second zone 2 are arranged alternately along the length of the fabric. The weft yarns of the third zone 3 are arranged alternately in a cycle of 48 weft yarns, and the weft yarns of the third zone 3 are located between the first zone 1 and the second zone 2 along the length of the fabric. Because the first zone 1 is formed by crepe weave, the second zone 2 is formed by two types of weave, and the third zone 3 is formed by plain weave, the first zone 1, the second zone 2 and the third zone 3 of the fabric are all formed by different weaves. Therefore, the overall design of the fabric has reduced the number of holes, which keeps the fabric intact and improves the strength of the fabric.

[0021] Within the range of weft yarns 1-60, warp yarns 33-40 interweave with weft yarns 1-48 and warp yarns 57-64 interweave with weft yarns 1-48 to form support area 21, and warp yarns 41-56 interweave with weft yarns 1-48 to form inner area 22. Within the range of weft yarns 61-120, warp yarns 1-8 interweave with weft yarns 61-108 and warp yarns 25-32 interweave with weft yarns 61-108 to form support area 21, and warp yarns 9-24 interweave with weft yarns 61-108 to form inner area 22. Therefore, each second region 2 includes two support areas 21 and an inner area 22, and the inner area 22 is located in the middle of the two support areas 21. The inner area 22 is formed by a convex weave structure, while the outer area 22 is formed by a single warp and double weft weave structure. Therefore, the inner area 22 is lower than the support area 21 due to the raised floats of the support area 21. Since the first area 1 uses a crepe weave, its floats are fewer than those of the support area 21, making the first area 1 lower than the support area 21. Because the total number of warp and weft floats in the first area 1 is greater than that in the inner area 22, the height difference H2 between the inner area 22 and the support area 21 is greater than the height difference H1 between the first area 1 and the support area 21. This results in different degrees of concavity in the fabric. Because the support area 21 is higher than the inner area 22, and the support area 22... The length of the float in support area 21 is longer than that in first area 1, and the float in first area 1 is greater than that in inner area 22. The overlapping or stacking of these floats increases the fabric thickness, thus increasing the thickness of support area 21. Therefore, the thickness D3 of support area 21 is greater than the thickness D2 of first area 1, and the thickness D2 of first area 1 is greater than the thickness D1 of inner area 22. This creates different heights and thicknesses in the fabric, increasing overall breathability. Because inner area 22 has a single warp and double weft structure, compared to plain weave, it features two weft yarns interlacing, resulting in greater breathability at the same density. Below, the internal area 22 has a looser and thinner structure than the plain weave, making it the thinnest and lowest point of the fabric. This results in different degrees of concavity and thickness across multiple areas of the fabric. Since the internal area 22 is both the thinnest and lowest point, it replaces the perforated structure. Because perforations are small, while the internal area 22 is large, existing perforation structures are elliptical, typically with a major axis diameter of 3mm-6mm and a minor axis diameter of 1mm-3mm. In this embodiment, the internal area 22 is rectangular, with a length of 1.5cm-4.5cm and a width of 0.5cm-1.The fabric's breathability is maintained by replacing the small area of ​​the perforations with a large area of ​​the inner zone 22 (5cm). Because the support zone 21 is located at the highest point and is the thickest, and is situated on both sides of the inner zone 22, it protects the inner zone 22, reducing fiber snagging or breakage, thereby increasing the overall strength of the fabric. Furthermore, the different degrees of indentation and thickness of multiple areas create a mutual balance, reducing the possibility of fabric deformation when stretched.

[0022] With the fabric having the same density throughout, the third region 3 is formed by the interlacing of warp yarns 1-64 and weft yarns 12. Because the third region 3 is located in the fabric width direction and is not interlaced with the first region 1 or the second region 2, but is located in the fabric length direction, the third region 3 is interlaced with the first region 1 and the second region 2. Furthermore, the third region 3 is a plain weave, therefore the fiber tightness at the edge of the third region 3 is high, making the third region 3 raised. Since the support area 21 is the highest point of the raised area, the height of the raised area 3 is equal to that of the support area 21. Therefore, the third region 3 is higher than the first region 1 and the inner region 22, thus creating different heights in both the length and width directions of the fabric. This results in the overall fabric having different heights. By creating a breathable gradient, and by varying the height and thickness of the fabric as a whole, breathability is increased while strength is also increased. A uniform thickness is avoided because if the fabric uses the same maximum height and thickness, breathability will be poor. If the height and thickness fall between the highest and lowest, and the thickness falls between the thickest and thinnest, overall breathability will be relatively affected. If the fabric uses the lowest height and thinnest, the loose structure will make the fabric too thin, which, while improving breathability, will also make it too transparent and prone to fiber breakage, thus affecting the fabric's overall quality.

[0023] Because the support area 21 is formed by 8 warp yarns and 48 weft yarns interwoven, the inner area 22 is formed by 16 warp yarns and 48 weft yarns interwoven, and the first area 1 is formed by 32 warp yarns and 48 weft yarns interwoven, the width of the support area 21 is half that of the inner area 22, and the width of the first area 1 is twice that of the inner area 22. Therefore, the edge of the inner area 22 is strengthened by the support area 21, so that the fabric as a whole forms the first gradient of breathability through the inner area 22 and the second gradient of breathability through the first area 1, while preventing the fabric from being too thin. At the same time, the different warp and weft structures increase the breathability of the fabric while increasing the overall strength of the fabric.
