Description

Technical Field

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

[0002] Most current antistatic fabrics use antistatic auxiliaries to achieve their antistatic properties. However, these auxiliaries can become damaged over time, thus affecting the overall antistatic properties of the fabric. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an antistatic fabric. This fabric uses interwoven warp and weft yarns to form a surface cross-shaped area and a reverse cross-shaped area. The warp and weft yarns in both the surface and reverse cross-shaped areas are from the first and second units, respectively. This creates an alternating layout of the surface and reverse cross-shaped areas on the front and back of the base fabric. Since the yarns of the first and second units are conductive fibers, a continuous conductive path is formed between the front and back of the fabric. This allows charges to move quickly along the conductive fibers, increasing charge dissipation efficiency and reducing static electricity accumulation. Furthermore, the cavities formed between the surface and reverse cross-shaped areas and the base fabric allow the charges in the base fabric to be concentrated and eliminated, thereby 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 base fabric area, a first unit and a second unit, wherein the first unit is alternately arranged on the surface and reverse side of the base fabric area along the fabric length direction, and the second unit is alternately arranged on the surface and reverse side of the base fabric area along the fabric width direction, thereby forming a cross area on both the fabric surface and the fabric reverse side, wherein the center of the cross area is located at the intersection of the first unit and the second unit.

[0005] The present invention is further configured such that, located on the surface of the fabric, the first unit is in a state where the two sides gradually bulge towards the middle, and the second unit is in a state where the two sides gradually bulge towards the middle.

The 81st to 160th warp yarns and the 81st to 160th weft yarns are interwoven to form the first unit and the second unit, which are arranged on the front side of the base fabric area.

[0011] The present invention is further configured such that, within the interlacing range of the 1st to 80th warp yarns and the 1st to 80th weft yarns, the odd number of warp yarns in the 21st to 60th warp yarns constitutes the first unit, and the odd number of weft yarns in the 21st to 60th weft yarns constitutes the second unit;

[0029] 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.

[0030] like Figure 1 — Figure 7 As shown, this embodiment discloses an antistatic fabric. The fabric has a weave of 160 warp yarns and 160 weft yarns per cycle. The fabric includes a base fabric area 300, a first unit 201, and a second unit 202. In one weave cycle, the odd-numbered warp yarns and the odd-numbered weft yarns within the 160 warp yarns interweave to form the fabric surface, and the even-numbered warp yarns and the even-numbered weft yarns within the 160 warp yarns interweave to form the fabric reverse side. Within the interweaving range of the 1st to 80th warp yarns and the 1st to 80th weft yarns, the odd-numbered warp yarns within the 21st to 60th warp yarns form the first unit 201, and the odd-numbered weft yarns within the 21st to 60th weft yarns form the second unit 202. In the second unit 202, the remaining warp and weft yarns interweave to form the base fabric area 300. However, because the odd number of warp yarns in the 160 warp yarns interweaves with the odd number of weft yarns in the 160 weft yarns to form the fabric surface, and the even number of warp yarns in the 160 warp yarns interweaves with the even number of weft yarns in the 160 weft yarns to form the fabric reverse side, and the even number of warp yarns interweaves with the even number of weft yarns to form the fabric reverse side, within the interweaving range of the 1-80 warp yarns and the 1-80 weft yarns, the odd number of warp yarns interweaves with the odd number of weft yarns to form the fabric surface. Thus, at this time, the interweaving of the 1-80 warp yarns and the 1-80 weft yarns forms the first unit 201 and the second unit 202, which are arranged on the surface of the base fabric area 300.

[0031] Within the interlacing range of warp yarns 1-80 and weft yarns 81-160, the even-numbered warp yarns within warp yarns 21-60 form the first unit 201, and the even-numbered weft yarns within warp yarns 101-140 form the second unit 202. The remaining warp and weft yarns interlac to form the base fabric area 300. However, because the odd-numbered warp yarns within the 160 warp yarns interlac to form the fabric surface, and the even-numbered warp yarns within the 160 warp yarns interlac to form the fabric reverse side, within the interlacing range of warp yarns 1-80 and weft yarns 81-160, the odd-numbered warp yarns interlac to form the fabric surface, and the even-numbered warp yarns interlac to form the fabric reverse side. Thus, at this time, the interlacing of warp yarns 1-80 and weft yarns 81-160 forms the first unit 201 and the second unit 202, which are located on the reverse side of the base fabric area 300.

[0032] Within the interlacing range of warp yarns 81-160 and weft yarns 1-80, the even-numbered warp yarns within 101-140 form the first unit 201, and the even-numbered weft yarns within 21-60 form the second unit 202. The remaining warp and weft yarns interlac to form the base fabric area 300. However, because the odd-numbered warp yarns within 160 warp yarns interlac to form the fabric surface, and the even-numbered warp yarns within 160 warp yarns interlac to form the fabric reverse side, within the interlacing range of warp yarns 81-160 and weft yarns 1-80, the odd-numbered warp yarns interlac to form the fabric surface, and the even-numbered warp yarns interlac to form the fabric reverse side. Therefore, at this time, the interlacing of warp yarns 81-160 and weft yarns 1-80 forms the first unit 201 and the second unit 202, which are located on the reverse side of the base fabric area 300.

[0033] Within the interlacing range of warp yarns 81-160 and weft yarns 81-160, the odd-numbered warp yarns within warp yarns 101-140 form the first unit 201, and the odd-numbered weft yarns within weft yarns 101-140 form the second unit 202. The remaining warp and weft yarns interlac to form the base fabric area 300. However, because the odd-numbered warp yarns within 160 warp yarns interlac to form the fabric surface, and the even-numbered warp yarns within 160 warp yarns interlac to form the fabric reverse side, within the interlacing range of warp yarns 81-160 and weft yarns 81-160, the odd-numbered warp yarns interlac to form the fabric surface, and the even-numbered warp yarns interlac to form the fabric reverse side. Therefore, at this time, the warp yarns 81-160 and weft yarns interlac to form the first unit 201 and the second unit 202, which are arranged on the front side of the base fabric area 300.

[0034] Therefore, the 1st to 160th warp yarns and the 1st to 160th weft yarns are interwoven to form a "field" - shaped structure. The 80th warp yarn and the 81st warp yarn are the exchange points of the front and back warp yarns. The 160th warp yarn and the 1st warp yarn are the exchange points of the front and back warp yarns. The 80th weft yarn and the 81st weft yarn are the exchange points of the front and back weft yarns. The 160th weft yarn and the 1st weft yarn are the exchange points of the front and back weft yarns. Therefore, the first unit 201 is alternately arranged on the front and back surfaces of the base fabric area 300 along the fabric length direction, and the second unit 202 is alternately arranged on the front and back surfaces of the base fabric area 300 along the fabric width direction. Thus, the fibers of the first unit 201 and the fibers of the second unit 202 form a continuous conductive path, enabling charges to move quickly along the conductive fibers, reducing the generation of static electricity, and further increasing the antistatic property of the fabric.

[0035] The first unit 201 and the second unit 202 form a cross area 200 on both the surface and the reverse side of the fabric. Taking the interlacing range of warp yarns 1-80 and weft yarns 1-80 as an example, within this interlacing range, the first unit 201 is located on the odd-numbered warp yarns of warp yarns 21-60, and the second unit 202 is located on the odd-numbered weft yarns of weft yarns 21-60. The warp yarns of the first unit 201 interlace with the weft yarns of the base fabric area 300 and the weft yarns of the second unit 202, and the weft yarns of the second unit 202 interlace with the warp yarns of the base fabric area 300 and the warp yarns of the first unit 201. Therefore, the center of the first unit 201 and the second unit 202 is where the warp yarns of the first unit 201 interlace with the weft yarns of the second unit 202. The weft yarns interweave, and the center of the cross area 200 is located at the intersection of the first unit 201 and the second unit 202. Among the warp and weft yarns that interweave to form the cross area 200, warp yarns 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, and 51 interweave with weft yarns 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, and 51 to form a double warp and double weft pattern. Warp yarns 21, 23, 25, 27, 53, 55, 57, and 59 interweave with weft yarns 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, and 59 to form a double warp and single weft pattern. Warp yarns 33, 35, 37, 39, 41, 43, 45, 47, 49, and 51 interweave with weft yarns 21, 23, 25, 27, 53, 55, 57, and 59 to form a double warp and single weft pattern. Odd-numbered warp yarns within warp yarns 21-60 are floats located between weft yarns 1-20 and 61-80. Odd-numbered weft yarns within weft yarns 21-60 are floats located between warp yarns 1-20 and 61-80. Therefore, they are located on the fabric surface. Unit 201 and Unit 202 both have a gradually convex shape from both sides towards the center. They are located on the reverse side of the fabric. Unit 201 and Unit 202 both have a gradually convex shape from both sides towards the center because they interweave with warp yarns 1-80 and... Within the interlacing range of weft yarns 1-80, warp yarns 1-20 and 61-80 are both cotton fibers; odd-numbered warp yarns within warp yarns 21-60 are conductive fibers, and even-numbered warp yarns within warp yarns 21-60 are cotton fibers. Within the interlacing range of weft yarns 1-80 and 81-160, warp yarns 1-20 and 61-80 are both cotton fibers; even-numbered warp yarns within warp yarns 21-60 are conductive fibers, and even-numbered warp yarns within warp yarns 21-60 are cotton fibers. Weft yarns 81-100 and 141-160 are both cotton fibers.Even-numbered weft yarns within warp yarns 101-140 are conductive fibers, and odd-numbered weft yarns within the same range are cotton fibers. Within the interlacing range of warp yarns 81-160 and weft yarns 1-80, warp yarns 81-100 and 141-160 are both cotton fibers. Even-numbered warp yarns within warp yarns 101-140 are conductive fibers, and odd-numbered warp yarns within the same range are cotton fibers. Weft yarns 1-20 and 61-80 are both cotton fibers. Even-numbered weft yarns within weft yarns 21-60 are conductive fibers, and odd-numbered weft yarns within the same range are cotton fibers. Within the interlacing range of warp yarns 81-160 and weft yarns 81-160, warp yarns 81-100 and 141-160 are both cotton fibers. Odd-numbered warp yarns within warp yarns 101-140 are conductive fibers. Even-numbered warp yarns in warp yarns 101-140 are cotton fibers, as are weft yarns 81-100 and 141-160. Odd-numbered weft yarns in warp yarns 101-140 are conductive fibers, while even-numbered weft yarns in warp yarns 101-140 are cotton fibers. Therefore, the cross-section 200 extends from its center towards both the first unit 201 and the second unit 202. The center of the cross-section 200 has the strongest conductivity, and the conductivity gradually decreases towards both sides of the first unit 201 and the second unit 202. This structure of the cross-section 200 forms a conductive network on both the surface and reverse side of the fabric, allowing charge to be released not only on the surface and reverse side but also in multiple directions, thus reducing the generation and accumulation of static electricity.

[0036] Because the warp and weft yarns of the first unit 201 and the second unit 202 have the same interlacing structure, and the tension between the fibers is reduced through the central double warp and double weft structure of the cross zone 200 towards the floating yarn structures on both sides of the first unit 201 and the second unit 202, the protrusion height of the first unit 201 on the fabric surface is the same as that of the first unit 201 on the reverse side of the fabric, and the protrusion height of the second unit 202 on the fabric surface is the same as that of the second unit 202 on the reverse side of the fabric. Therefore, a first cavity 400 is formed between the first unit 201 and the base fabric area 300, and the second unit 202... A second cavity 500 is formed between the base fabric area 300 and the base fabric area 400. Since both the first cavity 400 and the second cavity 500 gradually decrease from the center of the cross area 200 towards both sides of the first unit 201 and the second unit 202, and the center of the cross area 200 is where the conductive fibers are most abundant, the conductive fibers at the center of the cross area 200 can concentrate and neutralize the charge, reducing the situation of excessive local charge. At the same time, the presence of the cavity increases the breathability of the fabric, so the moisture generated by the environment or human body can more easily enter the fabric and thus the charge can be leaked through the adsorption of moisture on the fibers, thereby reducing the accumulation of charge on the surface of the fabric.

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