AI Technical Summary
Polyester fabrics on the market tend to accumulate static electricity in dry environments, leading to increased conductivity but reduced breathability.
By introducing conductive fibers into polyester fabric, a first region with a tight structure is formed by interweaving double-strand yarns and single-strand polyester fibers, while the second region does not interweave conductive fibers, forming a raised area and a base fabric. This increases charge conduction while leaving gaps to improve air permeability.
While maintaining conductivity, the uniform distribution of conductive fibers and the design of raised areas improve the breathability and structural stability of the polyester fabric, reduce static electricity accumulation, and enhance air circulation and water vapor evaporation.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabrics, and more specifically, to a polyester fabric. Background Technology
[0002] Currently, polyester fabrics on the market are made of chemical fibers, which make them prone to accumulating static electricity in dry environments. This leads to the interweaving of conductive fibers with polyester fibers to improve the conductivity of the polyester fabric. However, the interwoven polyester fabric structure is often quite tight. While a tight fabric structure is beneficial for the even distribution of conductive fibers and the conduction of charges, it also restricts air circulation, thus reducing the breathability of the fabric. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a polyester fabric that increases the conductivity of the polyester fabric through conductive fibers. At the same density, the fabric's structural compactness is increased by combining double-ply conductive fibers with single-ply polyester fibers, allowing the conductive fibers to be evenly distributed and facilitating charge conduction. Simultaneously, because the density is the same, the gaps between the warp and weft yarns in the single-ply yarns are large, thus increasing the fabric's breathability. Furthermore, the double-ply yarns do not interweave in some areas, allowing the conductive fibers to increase charge conduction while creating cavities between the non-interwoven and interwoven yarns, thereby increasing air circulation. Additionally, some charge can be carried away by water vapor evaporation.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a polyester fabric, comprising a first region and a second region, the second region comprising a second raised region and a second base fabric, wherein the second base fabric is higher than the first region in the front direction of the fabric, and lower than the first region in the reverse direction of the fabric, the first region comprising a first raised region and a first base fabric, the first base fabric being connected to the second base fabric, the second raised region being connected to the first raised region, and the second raised region and the second base fabric forming a cavity.
[0005] The present invention is further configured such that the first region and the second region are arranged alternately along the fabric width direction, and along the fabric length direction, a second region is provided between every two adjacent first regions, and a first region is provided between every two adjacent second regions.
[0006] The present invention is further configured such that the first region includes six first protrusions, and the second region includes six second protrusions.
[0007] The present invention is further configured such that the width M of the first protrusion area is 2-3 times the width L of the second protrusion area, and the height N of the first protrusion area is the same as the height D of the second protrusion area.
[0008] The present invention is further configured such that the height H of the cavity is 0.3cm-0.6cm.
[0009] The present invention is further configured such that the polyester fabric has 56 warp yarns and 96 weft yarns as one cycle, each first region has 19 warp yarns and 48 weft yarns interwoven, and each second region has 9 warp yarns and 48 weft yarns interwoven.
[0010] The present invention is further configured such that the polyester weft yarn includes a first yarn and a second yarn, wherein the first yarn is made of 75D / 144F polyester fiber and the second yarn is made of 50-count double-strand conductor fiber.
[0011] The present invention is further configured such that the warp yarn of the polyester fabric is made of 75D / 144F polyester fiber.
[0012] In summary, this utility model has the following beneficial effects:
[0013] Two regions are formed by the interlacing of warp and weft yarns. The first and second regions are connected by different numbers of interlacing structures at their edges, creating a raised area in the second region to reduce the contact area of the fabric and thus reduce static electricity. At the same density, the double-strand conductive fibers and single-strand polyester fibers increase the fabric's structural compactness, which is beneficial for the uniform conduction of charges. At the same time, the large gaps between the single-strand polyester fibers increase the fabric's breathability. In some areas, the double-strand conductive fibers do not interlace, forming cavities at the interlacing points. This not only increases air circulation but also removes some charges through water vapor evaporation. Furthermore, the non-interlaced conductive fibers can form more direct conductive paths, thereby improving the fabric's conductivity. Attached Figure Description

[0020] 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.
[0021] This embodiment discloses a polyester fabric, including a first region 100 and a second region 200. The polyester fabric is arranged in a cycle of 56 warp yarns and 96 weft yarns. Each first region 100 consists of 19 warp yarns and 48 weft yarns interwoven. (Refer to...) Figure 5 Taking the first region 100 formed by the interlacing of warp yarns 1-19 and weft yarns 1-48 as an example, the polyester warp yarns are made of 75D / 144F polyester fiber, and the weft yarns include a first yarn 301 and a second yarn 302. The first yarn 301 is made of 75D / 144F polyester fiber, and the second yarn 302 is made of 50-count double-ply conductive fiber. Therefore, in the first region 100, the first yarn 301 is used for weft yarns 1-6, and the second yarn 302 is used for weft yarns 7-8. The process involves a cycle of 6 first yarns 301 and 2 second yarns 302, thus ensuring that each... There are 2 conductive fibers every 6 polyester fibers. Therefore, when the warp and weft yarns interweave, the 2 conductive fibers in the weft direction interweave with the polyester fibers in the warp direction to form the first raised area 101, and the 6 polyester fibers in the weft direction interweave with the polyester fibers in the warp direction to form the first base fabric 102. Since the first area 100 adopts a plain weave structure, the structural density of the fabric is increased. The conductive fibers are double-ply yarns, and the polyester fibers are single-ply yarns. Therefore, when the fabric is interwoven, the conductive fibers can neutralize more charges at the same density. At the same time, the cyclic arrangement of the yarns allows the conductive fibers to be evenly distributed, thereby increasing the conduction of charges.
[0022] Each second region 200 consists of 9 warp yarns and 48 weft yarns interwoven. Taking the second region 200 formed by the interweaving of warp yarns 20-28 and weft yarns 1-48 as an example, the polyester warp yarns are made of 75D / 144F polyester fiber, and the weft yarns include first yarn 301 and second yarn 302. First yarn 301 is made of 75D / 144F polyester fiber, and second yarn 302 is made of 50-count double-ply conductive fiber. Therefore, in the second region 200, weft yarns 1-6 use first yarn 301, and weft yarns 7-8 use second yarn 302, with 6 first yarns 301 and 2 second yarns 302. The yarn 302 is circulated, but the conductive fibers do not interweave in the second region 200. Therefore, the weft polyester fibers interweave with the warp polyester fibers to form the second base fabric 202, while the weft conductive fibers do not interweave with the warp polyester fibers, thereby forming the second raised area 201 of the conductive fibers. Because the conductive fibers do not interweave at this time, the conductive fibers in the second region 200 can be evenly distributed, and the formation of the second raised area 201 has a more direct conductive path, thereby reducing the charge transfer loss in the fiber parts, improving the overall conductivity of the fabric, and reducing fiber damage caused by the interweaving of warp and weft yarns during the weaving process.
[0023] Because the first region 100 includes the first raised area 101 and the first base fabric 102, and the second region 200 includes the second raised area 201 and the second base fabric 202, and the connection between the first region 100 and the second region 200, namely the 20th warp yarn and the 28th warp yarn, is connected by a three-up-one-down weave, because the number of warp weave points on the 20th warp yarn and the 28th warp yarn is three times that of the other warp weave points, when the warp and weft yarns interweave, the 20th warp yarn and the 28th warp yarn will be tighter than the other warp yarns, thus pulling the warp yarns on both sides together, causing the second region 200 to arch due to compression at the interweaving point. Thus, on the front side of the fabric, the second base fabric 202 is higher than the first region 100, and on the back side of the fabric, the second base fabric 202 is lower than the first region 100, thereby reducing the contact area of the fabric and reducing the generation of electrical charge. Furthermore, because the base fabric 202 forms a raised area, it increases the air circulation of the fabric and increases the breathability of the fabric.
[0024] Because both the first base fabric 102 and the second base fabric 202 are located at the intersection of the 1st to 6th weft yarns and the warp yarns, and both the first raised area 101 and the second raised area 202 are located at the intersection of the 7th and 8th weft yarns and the warp yarns, and are circulated with 6 first yarns 301 and 2 second yarns 302, the first base fabric 102 and the second base fabric 202 are connected, and the second raised area 201 is connected to the first raised area 101. Because the second raised area 201 is connected to the first raised area 101, the length of the non-interlaced conductive fiber weft of the second raised area 201 is interrupted by the conductive fiber of the first raised area 101, thereby reducing the phenomenon of the conductive fiber of the second raised area 201 breaking due to snagging, thus increasing the structural stability of the fabric.
[0025] Because the first region 100 and the second region 200 are arranged alternately along the fabric width direction, and along the fabric length direction, a second region 200 is provided between every two adjacent first regions 100, and a first region 100 is provided between every two adjacent second regions 200. The first region 100 includes 6 first raised areas 101, and the second region 200 includes 6 second raised areas 201. Because the first raised areas 101 are double-stranded conductive wires interwoven, while the second raised areas 201 are not interwoven, and both the first base fabric 102 and the second base fabric 202 are plain weave interwoven, the second raised areas 201 can reduce the resistance caused by the yarn being flattened or deformed due to the interweaving of the conductive fibers in the first raised areas 101 while increasing the density of the fabric structure.
[0026] Because the width M of the first raised area 101 is 2-3 times the width L of the second raised area 201, preferably 2.7 times the width L of the second raised area 201, and the height N of the first raised area 101 is the same as the height D of the second raised area 201, the connection between the first raised area 101 and the second raised area 201 allows for uniform charge conduction in the fabric, thereby increasing the conductivity of the fabric. However, because the second base fabric 202 is arched due to its connection with the first area 100, the second base fabric 202 is convex on the front side of the fabric and concave on the reverse side. Since the second raised area 201 does not interweave, the second raised area 201 will not follow the second base fabric... The second raised area 201 and the second base fabric 202 are raised or recessed, thus forming a cavity 203. The height H of the cavity 203 is 0.3cm-0.6cm, preferably 0.5cm. The formation of the cavity 203 creates a certain space between the second raised area 201 and the second base fabric 202, thereby increasing the air circulation of the fabric. When the human body produces water vapor, it can not only breathe through the pore difference formed between the double-strand yarn and the single-strand yarn, but also diffuse water vapor more quickly through the cavity 203, thereby allowing the fabric to evaporate water vapor, remove some of the charge, and increase the breathability of the fabric, thus keeping the fabric dry and comfortable.

All technical solutions falling within the scope of this utility model's concept are protected.
