Description

Technical Field

[0001] This utility model relates to a polyester fabric, specifically a high-strength antistatic polyester fabric. Background Technology

[0002] Polyester, or polyethylene terephthalate, is one of the most widely produced and used synthetic fibers. Polyester fabric, with its excellent properties such as high strength, abrasion resistance, wrinkle resistance, easy washing and quick drying, and dimensional stability, is widely used in clothing, home textiles, and industrial textiles. In clothing, it is commonly used to make suits and sportswear; in home textiles, it is used for curtains and sofa covers; and in industrial applications, it is used to make geotextiles, filter materials, and conveyor belts. However, the lack of hydrophilic groups in the polyester molecule results in poor moisture absorption, making the fabric prone to static electricity buildup. Static electricity not only attracts dust and affects the appearance of the fabric but can also cause electric shocks, interfere with the operation of precision electronic equipment, and pose a fire or explosion hazard in flammable and explosive environments. Furthermore, with the increasing demands for material performance in industrial textiles, ordinary polyester fabric cannot meet the strength requirements under high loads and high stress environments, limiting its application. Therefore, this application provides a high-strength antistatic polyester fabric. Utility Model Content

[0003] The purpose of this invention is to provide a high-strength antistatic polyester fabric, which is designed to have higher strength and a certain antistatic effect than ordinary polyester fabric, thus better meeting consumer needs.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: A high-strength antistatic polyester fabric, comprising: a polyester fabric body, wherein the polyester fabric body is a warp-knitted axial fabric, the warp-knitted axial fabric is woven from three guide bars (GB1, GB2, and GB3) and an MSU weft insertion device; high-strength abrasion-resistant yarns are inserted into GB1; antistatic polyester yarns are inserted into GB2 and GB3; high-strength antistatic yarns are inserted into the MSU; the weft insertion numbers of the three guide bars (GB1, GB2, and GB3) are as follows:

[0005] GB1: 1-0 / 2-3 / 1-0 / 2-3 / / ;

[0006] GB2: 0-0 / 1-1 / 0-0 / 2-2 / / ;

[0007] GB3: 0-0 / 2-2 / 0-0 / 1-1 / / .

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the antistatic yarn is graphene-modified polyester fiber yarn.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the high-strength abrasion-resistant yarn is high-strength abrasion-resistant vinylon yarn.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the high-strength antistatic yarn is a meta-aramid-based conductive fiber yarn.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: antistatic agent is attached to both sides of the polyester fabric body.

[0012] The beneficial effects of this utility model are as follows: Based on the high-strength antistatic polyester fabric of this utility model, the transverse density of the warp-knitted axial fabric is relatively large, and the fabric tightness is good; it reduces the creasing and straightening of the yarn caused by interlacing, with only a slight creasing in the binding yarn. When subjected to external force, the parallel straightening reinforcing yarns bear the load simultaneously, reducing stress concentration and ensuring the strength utilization rate of the fiber. It has excellent tear resistance. Combined with antistatic polyester yarn and high-strength antistatic yarn, it improves the antistatic effect of the main body of the polyester fabric. Compared with ordinary polyester fabric, it can better meet the needs of consumers. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1

[0018] Combination Figure 1-3 This embodiment provides a detailed description of a high-strength antistatic polyester fabric, comprising: a polyester fabric body, wherein the polyester fabric body is a warp-knitted axial fabric, the warp-knitted axial fabric being woven from three guide bars (GB1, GB2, and GB3) and an MSU weft insertion device; high-strength abrasion-resistant yarns are inserted into GB1; antistatic polyester yarns are inserted into GB2 and GB3; high-strength antistatic yarns are inserted into the MSU; the weft insertion numbers of the three guide bars (GB1, GB2, and GB3) are as follows:

[0019] GB1: 1-0 / 2-3 / 1-0 / 2-3 / / ;

[0020] GB2: 0-0 / 1-1 / 0-0 / 2-2 / / ;

[0021] GB3: 0-0 / 2-2 / 0-0 / 1-1 / / .

[0022] Warp-knitted axial fabrics are oriented fabrics woven on warp-knitting machines with both warp and weft yarns. Besides excellent in-plane mechanical properties, warp-knitted axial fabrics also exhibit significantly enhanced mechanical properties in the thickness direction. Furthermore, they possess superior tear resistance compared to traditional reinforced fabrics due to the fully straightened arrangement of the interlining yarns and their binding structure with tie yarns. In warp-knitted axial fabrics, the yarns are in a fully straight state, fully utilizing the high strength and high modulus characteristics of the interlining yarns. In contrast, in woven fabrics, the warp and weft yarns are interwoven, resulting in a bent yarn state that prevents the full utilization of high-performance yarns. Because the yarns in warp-knitted axial fabrics are distributed in different planes, when the fabric is stretched in one direction, the yarns in the other direction do not break due to shearing. Instead, the tie yarns form a grid that prevents the tear from widening, thus giving warp-knitted axial fabrics superior tear resistance.

[0023] In this embodiment, the yarn inserted into GB1 serves as the braiding yarn, while GB2 and GB3 act as fully inserted weft guide bars, forming alternating weft padding. Because the weft padding yarn has a larger diameter, it creates a vertically inserted warp padding effect; therefore, the inserted yarn can also be called warp padding. The yarn inserted into MSU is full-width weft padding. There is no interlacing between the warp padding and the full-width weft padding, allowing them to stretch parallel and form two yarn layers arranged perpendicularly to each other and bound together by the braiding yarn. In this embodiment, the diameter of the warp padding yarn is much larger than that of the braiding yarn, causing the braiding yarn to bend while the weft padding yarn remains straight, forming the surface texture of the warp padding. The weft padding guide bars also function as warp padding, increasing the warp padding density. Two warp padding guide bars are positioned one in front of the other, alternately padding the yarn.

[0024] The warp-knitted axial fabric combines variable weft insertion and warp plain weave. When the weft insertion extension line and the warp plain backing yarn are in the same direction and of the same length, the weft yarn in this section will slide onto the warp plain extension line on the reverse side. If this condition is not met, the weft yarn will be pressed under the front comb extension line, thus alternating the weft yarn on both sides of the warp plain extension line. A single MSU is then inserted into the full width of the weft insertion yarn, giving the fabric surface a texture similar to woven fabric. However, compared to woven fabric, this warp-knitted axial fabric has a higher transverse density and better fabric tightness; it reduces yarn creasing caused by interlacing, with only slight creasing in the binding yarns. When subjected to external force, the parallel, straight reinforcing yarns simultaneously bear the load, reducing stress concentration and ensuring the high utilization rate of fiber strength.

[0025] Furthermore, the antistatic yarn is a graphene-modified polyester fiber yarn. The graphene-modified polyester fiber is prepared by a blending modification method, first by co-extruding graphene powder with polyethylene terephthalate to prepare graphene masterbatch, and then by blending the graphene masterbatch with PET chips and spinning. In this embodiment, the graphene powder mass fraction in the graphene-modified polyester fiber is 1.0%, and when the fiber is stretched 3.8 times, the fiber's breaking strength is 2.8 cN / dtex, its breaking elongation is 46.2%, and its volume resistivity is 3.29 × 10⁻⁶. 7 It has a strength of Ω·cm and exhibits good mechanical and antistatic properties.

[0026] Furthermore, the high-strength abrasion-resistant yarn is high-strength abrasion-resistant vinylon yarn. Vinylon not only possesses properties such as acid and alkali resistance, anti-moth, mildew resistance, insect resistance, high strength, high modulus, and good impact resistance, but also has good hydrophilicity and higher moisture absorption than other synthetic fibers. Due to its good abrasion resistance and high strength (single fiber strength above 7.5 cN / dtex) and high elongation, high-strength abrasion-resistant vinylon yarn can be used in textiles such as combat training clothing, work clothes for industrial and mining enterprises, car seat covers, and tarpaulins.

[0027] Furthermore, the high-strength antistatic yarn is a meta-aramid-based conductive fiber yarn. Conductive fibers are functional fibers that eliminate static electricity through electron conduction and corona discharge. Because the resistivity of conductive fibers is much lower than that of ordinary fibers, and their charge half-life is very short, conductive fibers can eliminate static electricity in a very short time. As a conductive fiber, meta-aramid-based conductive fiber, in addition to possessing the excellent mechanical properties, flame retardant properties, and high-temperature resistance of meta-aramid, also has excellent conductivity.

[0028] Example 2

[0029] Based on Example 1, an antistatic agent is attached to both sides of the polyester fabric body. Specifically, the antistatic agent is EA-1 antistatic agent. The preparation method of EA-1 antistatic agent is as follows: 5.0g of adipic acid and 5.0g of triethanolamine are added to a three-necked flask, heated to 100°C, and magnetically stirred until the solid powder is completely dissolved. Then, 0.05g of toluenesulfonic acid is added, the temperature is raised to 10-20°C, and heated for 3 hours to obtain EA. Using N,N-dimethylacetamide as a solvent, 4.0g of sodium chloroacetate is added to triacetyl adipic acid, and the mixture is heated at 80°C for 8 hours until the solvent is completely evaporated to obtain EA-1 antistatic agent. EA-1 antistatic agent can form a uniform conductive film on both sides of the polyester fabric body, improving the antistatic properties of the polyester fabric body.
