Anti-static fabric

Abstract

This utility model discloses an antistatic fabric, comprising a surface layer, an inner layer, and connecting threads. The connecting threads are conductive fibers or conductive filaments that connect the surface layer and the inner layer together, making both the front and back sides of the fabric semiconductors. By impregnating with a fluorinated water- and oil-repellent agent, and using a polytetrafluoroethylene microporous membrane as a barrier layer on the top surface of the surface layer, this invention comprehensively addresses the four core risks faced by protective clothing fabrics in special industrial environments: static electricity hazards, chemical corrosion (especially acids), high temperature threats, and physical damage (tears, abrasions). Simultaneously, it improves comfort and structural stability, thereby comprehensively enhancing the safety performance and wearing comfort of the protective clothing.

Description

Technical Field

[0001] This utility model belongs to the field of protective clothing fabric technology, specifically an antistatic fabric. Background Technology

[0002] Ordinary protective clothing fabrics are prone to generating and accumulating static electricity in specific working environments (such as electronic, chemical, and dusty environments). Accumulated static electricity can not only interfere with precision equipment, but more seriously, it poses a significant safety risk of discharging and igniting flammable or explosive materials or causing electric shocks to operators.

[0003] In typical conductive fabrics, the conductive fibers are mainly embedded on the back of the fabric to improve its appearance and smoothness. The back of the fabric is a semiconductor, while the front is an insulator. Therefore, once the fabric is made into clothing, it primarily eliminates static electricity generated by friction between the garment and the human body, but cannot eliminate static electricity generated by friction with external devices. Charge will still accumulate on the front of the garment.

[0004] In environments such as chemical plants, laboratories, and electroplating plants where acidic substances are present, ordinary protective clothing fabrics are easily corroded, dissolved, or degraded by acid, thus losing their protective function. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes an antistatic fabric.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an antistatic fabric, comprising:

[0007] The surface layer is composed of surface layer warp and surface layer weft lines;

[0008] The inner layer is composed of inner layer warp and inner layer latitude lines interwoven;

[0009] Connecting wires are used to connect the outer layer and the inner layer together, and the connecting wires are conductive fibers or conductive filaments.

[0010] Furthermore, the connecting line is a connecting warp line with stripes spaced 5-10 mm apart, interwoven with the surface weft and inner weft lines.

[0011] Furthermore, the connecting line is a connecting weft line, with stripes spaced 5-10 mm apart, interwoven with the surface warp and inner warp.

[0012] Furthermore, the connecting lines include connecting warp lines and connecting weft lines, arranged in a grid pattern with a spacing of 5-10 mm. The connecting warp lines interweave with the surface weft lines and the inner weft lines, and the connecting weft lines interweave with the surface warp lines and the inner warp lines.

[0013] Furthermore, both the warp and weft threads of the surface layer are polyester filaments or aramid filaments.

[0014] Furthermore, both the inner warp and inner weft threads are cotton threads.

[0015] Furthermore, the fabric is impregnated with a fluorinated water- and oil-repellent agent.

[0016] Furthermore, a barrier layer is provided on the top surface of the surface layer, and the barrier layer is a polytetrafluoroethylene microporous membrane.

[0017] The beneficial effects of this utility model are:

[0018] 1. The connecting thread is a conductive fiber or conductive filament. By connecting the warp threads to the outer weft threads and the inner weft threads, and connecting the weft threads to the outer warp threads and the inner warp threads, both the front and back of the fabric become semiconductors. Moreover, the positive and negative charges on the fabric surface can be conducted and cancel each other out, which can quickly and evenly eliminate static electricity generated by the human body and clothing, as well as static electricity generated on the surface of the clothing when in contact with the outside world. There is no charge accumulation in the clothing.

[0019] 2. The polytetrafluoroethylene (PTFE) microporous membrane acts as a barrier layer, providing waterproofing and breathability. Working synergistically with fluorinated water and oil repellents, it effectively blocks acid erosion of the fabric and also possesses certain high-temperature resistance. Together with the aramid layer, it enhances the safety of the protective clothing in high-temperature environments. The outer layer of polyester filament and aramid yarn is strong and durable; the inner layer of cotton yarn is skin-friendly, moisture-wicking, and breathable. This comprehensive approach addresses the four core risks faced by protective clothing fabrics in special industrial environments: static electricity hazards, chemical corrosion (especially acids), high-temperature threats, and physical damage (tears, abrasion), while simultaneously improving comfort and structural stability, thereby comprehensively enhancing the safety performance and wearing comfort of the protective clothing.
