Description

Technical Field

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

[0002] Traditional chiffon fabrics use a plain weave and fine yarns, resulting in a loose fabric structure. This increases friction between the yarns, making it easier for static charge to accumulate. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an antistatic fabric. The recessed and striped areas are lower than the second unit and second region, creating a three-dimensional concave-convex structure through fabric interweaving. This reduces the contact area of ​​the fabric, thereby reducing friction and static electricity generation. Furthermore, the recessed and striped areas are distributed with a loosely woven floating yarn structure, reducing interweaving points compared to a loose plain weave structure. This increases the exposed area of ​​the yarns in the recessed and striped areas, increasing their contact area with air. The flowing air increases the interaction between the yarns and water molecules, accelerating the dissipation of static charge. The second unit and second region are separated by the recessed and striped areas, forming independent units, thus suppressing large-area static accumulation. Since the second unit, second region, and recessed and striped areas use the same warp or weft yarns, the shared yarns transfer charge from the interweaving points to the floating yarns. The contact area between the floating yarns and air then dissipates the static charge, further increasing the fabric's antistatic properties.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an antistatic fabric, comprising a first region and a second region, the first region and the second region being arranged in a grid pattern, the first region comprising a first unit and a second unit, the first unit and the second unit being arranged alternately along the fabric width direction, the first unit comprising a recessed area and a striped area, the recessed area and the striped area being arranged alternately along the fabric length direction, the second region and the second unit being at the same height, the recessed area and the striped area being at the same height, and the second region being higher than the recessed area.

[0005] The present invention is further configured such that the first region and the second region are the same size, and the width dimension of the second unit is the same as the length dimension of the strip region.

[0006] The present invention is further configured such that the width dimension of the first unit is 6-7 times the width dimension of the second unit, and the length dimension of the recessed area is 3 times the length dimension of the strip area.

[0007] The present invention is further configured such that the thickness H1 of the recessed area is half the thickness of the second region H2.

[0008] The present invention is further configured such that the fabric is woven with 42 warp yarns and 42 weft yarns to form two first regions and two second regions, each first region is woven with 21 warp yarns and 21 weft yarns, and each second region is woven with 21 warp yarns and 21 weft yarns.

[0009] The present invention is further configured such that 6 warp yarns and 21 weft yarns are interwoven to form the first unit, and 1 warp yarn and 21 weft yarns are interwoven to form the second unit.

[0010] The present invention is further configured such that 6 warp yarns and 3 weft yarns interweave to form the recessed area, and 6 warp yarns and 1 weft yarn interweave to form the striped area.

[0011] The present invention is further configured such that the second region and the second unit have a plain weave structure, and the recessed region and the strip region have a floating long line structure.

[0012] The present invention is further configured such that the warp yarn of the fabric is made of 25D polyester filament and the weft yarn is made of 28D polyester filament.

[0013] In summary, this utility model has the following beneficial effects:

[0014] By creating a three-dimensional textured structure in the fabric through recessed and striped areas that are lower than the second unit and second region, the contact area of ​​the fabric is reduced, thus decreasing static electricity generated by friction. Furthermore, the recessed and striped areas are distributed with a loose, long floating yarn structure, which reduces interlacing points compared to a loose plain weave structure. This increases the contact area of ​​the yarns in the recessed and striped areas with the air, thereby increasing the interaction between the yarns and water molecules. The second unit and second region are isolated by the recessed and striped areas, thus suppressing the accumulation of static electricity over a large area. Since the second unit, second region, and recessed and striped areas use the same warp or weft yarns, the shared yarns transfer the charge from the interlacing points to the floating yarns, and then the static charge is consumed through the contact between the floating yarns and the air, thereby increasing the physical antistatic properties of the fabric.

[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] like Figure 1 — Figure 4 As shown, this embodiment discloses an antistatic fabric, referring to... Figure 1 The fabric is oriented vertically (length) and horizontally (width). The warp yarns are made of 25D polyester filament, and the weft yarns are made of 28D polyester filament. The fabric is constructed with 42 warp yarns interlacing with 42 weft yarns to form a weave cycle. Warp yarns 1-21 interlac with weft yarns 1-21 to form region 1; warp yarns 22-42 interlac with weft yarns 1-21 to form region 2; and so on. Therefore, the fabric comprises region 1 and region 2, and is woven within a single weave cycle. In the ring, 42 warp yarns and 42 weft yarns interweave to form two first regions 1 and two second regions 2. Each first region 1 is formed by 21 warp yarns and 21 weft yarns interweaving, and each second region 2 is formed by 21 warp yarns and 21 weft yarns interweaving. Furthermore, the warp yarns adjacent to the first region 1 are the warp yarns of the second region 2, and the weft yarns adjacent to the first region 1 are also the weft yarns of the second region 2. Therefore, the first regions 1 and second regions 2 are interwoven in a crisscross pattern, which creates a structural difference between the two adjacent regions of the first region 1 and the second region 2, thereby promoting weak charge exchange or neutralization.

[0022] Within the area of ​​the 21 warp yarns and 21 weft yarns that interweave to form the first region 1, with Figure 4Taking the first region 1, formed by the interlacing of warp yarns 1-21 and weft yarns 1-21, as an example, the same principle applies to the others. Warp yarns 1-6 interlaced with weft yarns 1-21 to form the first unit 11; warp yarn 7 interlaced with weft yarns 1-21 to form the second unit 12; warp yarns 8-14 interlaced with weft yarns 1-21 to form the first unit 11; warp yarn 15 interlaced with weft yarns 1-21 to form the second unit 12; and warp yarns 16-21 interlaced with weft yarns 1-21 to form the first unit 11. Therefore, each first unit 11 is formed by the interlacing of 6 warp yarns and 21 weft yarns, and each second unit 12 is formed by the interlacing of 1 warp yarn and 21 weft yarns. The first region 1 is formed by the interlacing of the weft yarns, and thus includes a first unit 11 and a second unit 12. Since the warp yarns of the second unit 12 are located between the warp yarns of the first unit 11, and the second unit 12 and the first unit 11 use the same weft yarns, the first unit 11 and the second unit 12 are arranged alternately along the width of the fabric. Since the first unit 11 is a float structure and the second unit 12 is a plain weave structure, the second unit 12 is interwoven between the first units 11 so that the weaving points of the float structure of the first unit 11 are not too long, thereby reducing the phenomenon of fabric yarn breakage due to snagging, and thus increasing the structural stability of the fabric.

[0023] Within the area formed by the interlacing of the 6 warp yarns and 21 weft yarns of the first unit 11, with Figure 4Taking the first unit 11, formed by the interlacing of warp yarns 1-6 and weft yarns 1-21, as an example, the same principle applies to others. Warp yarns 1-6 interlaced with weft yarns 1, 5, 9, 13, 17, and 21 form a striped area 112, and warp yarns 1-6 interlaced with weft yarns 2, 3, 4, 6, 7, 8, 10, 11, 12, 14, 15, 16, 18, 19, and 20 form a recessed area 111. Therefore, the first unit 11 includes the recessed area 111 and the striped area 112. The fabric has two sections: a concave section 111 is formed by the interlacing of 6 warp yarns and 3 weft yarns, and a striped section 112 is formed by the interlacing of 6 warp yarns and 1 weft yarn. Since the concave sections 111 and striped sections 112 have the same warp yarns but different weft yarns, they are arranged alternately along the fabric length. Because the concave sections 111 are all weft float structures, while the striped sections 112 are formed by continuous warp weaving points on a single weft yarn, the concave sections 111... Alternating with striped areas 112, the continuous weft float structure of recessed areas 111 is interrupted. Striped areas 112 located at the edge of the first unit 11 connect the second region 2 with the recessed area 111. The second unit 12 is located between two adjacent recessed areas 111 and two adjacent striped areas 112 along the fabric width direction. Recessed areas 111, striped areas 112 and the second region 2 in the fabric length direction share the same warp yarns. Recessed areas 111, striped areas 112 and the second region 2 in the fabric width direction share the same weft yarns. Recessed areas 111, striped areas 112 and the second unit 12 in the fabric width direction share the same weft yarns. Therefore, recessed areas 111 and striped areas 112 not only prevent the charge from merging in the second region 2 and the second unit 12, but also connect with recessed areas 111 and striped areas 112 through shared yarns, thus providing a path for the limited migration of charge to recessed areas 111 and striped areas 112.

[0024] Because the first region 1 is formed by 21 warp yarns and 21 weft yarns interlacing, and the second region 2 is also formed by 21 warp yarns and 21 weft yarns interlacing, the first region 1 and the second region 2 are the same size. Because the second unit 12 is formed by 1 warp yarn and 21 weft yarns interlacing, and the strip area 112 is formed by 6 warp yarns and 1 weft yarn interlacing, the width dimension of the second unit 12 is the same as the length dimension of the strip area 112. Because the first unit 11 is formed by 6 warp yarns and 21 weft yarns interlacing, and the second unit 12 is formed by 1 warp yarn and 21 weft yarns interlacing, the width dimension of the first unit 11 is 6-7 times the width dimension of the second unit 12. Preferably, the width dimension of the first unit 11 is the width dimension of the second unit 12. The length dimension of the recessed area 111 is 6 times that of the striped area 112. The recessed area 111 is formed by 6 warp yarns and 3 weft yarns interlaced, while the striped area 112 is formed by 6 warp yarns and 1 weft yarn interlaced. Therefore, the length dimension of the recessed area 111 is 3 times that of the striped area 112. Since the recessed area 111 and the striped area 112 are floating yarn structures, while the second region 2 and the second unit 12 are plain weave structures, the recessed area 111 and the striped area 112 are distributed with floating long yarn structures. Compared with the loose plain weave structure, the number of interlacing points is reduced, thereby increasing the exposed area of ​​the yarn in the recessed area 111 and the striped area 112. This increases the contact area of ​​the yarn with air in the recessed area 111 and the striped area 112. Therefore, the interaction between the yarn and water molecules is increased by the flow of air, and the dissipation of static charge is accelerated by the water molecules.

[0025] Because the second region 2 and the second unit 12 have a plain weave structure, and the recessed area 111 and the striped area 112 have a floated yarn structure, five recessed areas 111 and six striped areas 112 are grouped together. Along the fabric width direction, two adjacent groups separate the second unit 12 to form an independent unit. Along the fabric length direction, three groups of recessed areas 111 and striped areas 112 are grouped together to form an independent unit. Because the second region 2 and the second unit 12 have a plain weave structure, and the recessed area 111 and the striped area 112 have a floated yarn structure, the second region 2 and the second unit 12 have more yarn interlacing points than the recessed area 111 and the striped area 112. Therefore, the second region 2 and the second unit 12 are at the same height, and the recessed area 111 and the striped area 112 are at the same height. The second region 2 is higher. In the recessed area 111, and because the recessed area 111 and the striped area 112 are floating structures, the thickness H1 of the recessed area 111 is half the thickness of the second area 2H2. Therefore, the loose floating structure of the recessed area 111 and the striped area 112 is lower than the plain weave structure of the second area 2 and the second unit 12. Therefore, although the recessed area 111 and the striped area 112 are loose structures, they do not come into contact with each other and rub against each other, so no static electricity is generated. The front and back surfaces of the fabric are interwoven to form a three-dimensional concave and convex structure, thereby reducing the contact area of ​​the fabric. In turn, the phenomenon of static electricity generated by friction is reduced by reducing the contact area. Furthermore, the second area 2 and the second unit 12 form an independent unit, which prevents the unobstructed and uniform accumulation of charge in the fabric width direction or the fabric length direction, thereby suppressing the accumulation of static electricity over a large area and reducing the overall static electricity performance.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
