Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile fabric technology, specifically to a polyester fabric with an antistatic structure. Background Technology
[0002] In the history of the textile industry, polyester (polyester fiber) has rapidly become one of the world's highest-produced synthetic fibers since its commercialization in the 1950s, thanks to its significant advantages such as high strength, abrasion resistance, and ease of care. It is widely used in clothing, home textiles, and industrial fabrics—from everyday T-shirts and jackets to outdoor gear like windbreakers and dust filter cloths in industrial settings, polyester fabrics are ubiquitous. However, polyester molecules lack hydrophilic groups, resulting in extremely low surface conductivity (the surface resistance of ordinary polyester can reach 10¹²-10¹⁰). 4 (Ω), this characteristic makes it extremely prone to static electricity buildup due to friction during production, wearing and use.
[0003] Existing polyester fabrics generally use surface spraying of antistatic agents. These antistatic agents gradually fall off with washing and friction. After 10-20 washes, the surface resistance of most products will rise from 10^8Ω to over 10^11Ω, essentially losing their antistatic effect. Therefore, to address the above problems, a polyester fabric with an antistatic structure is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a polyester fabric with an antistatic structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A polyester fabric with an antistatic structure includes a polyester layer and an antistatic coating. The antistatic coating is fixedly connected to the top of the polyester layer, and a first knitted layer is fixedly connected to the bottom of the polyester layer. A first stainless steel composite fiber layer is fixedly connected to the inside of the first knitted layer, and a first conductive fiber is fixedly connected to the inner side of the first stainless steel composite fiber layer. A connecting layer is fixedly connected to the bottom of the first knitted layer, and a second knitted layer is fixedly connected to the bottom of the connecting layer. A second stainless steel composite fiber layer is fixedly connected to the inside of the second knitted layer, and a second conductive fiber is fixedly connected to the inner side of the second stainless steel composite fiber layer. A skin-friendly layer is fixedly connected to the bottom of the second knitted layer, and a fleece layer is fixedly connected to the bottom of the skin-friendly layer. A metal rod penetrating the polyester layer and the antistatic coating is fixedly connected to the top of the first stainless steel composite fiber layer, and a conductive rivet head is fixedly connected to the top of the metal rod.
[0006] Preferably, the conductive rivet head and the metal rod are a group, and there are several groups in total. The conductive rivet head and the metal rod are evenly arranged at intervals on the top of the first stainless steel composite fiber layer.
[0007] Preferably, the first knitted layer, the first stainless steel composite fiber layer, and the first conductive fiber are arranged in a left-right direction, and the second knitted layer, the second stainless steel composite fiber layer, and the second conductive fiber are arranged in a front-back direction. The first knitted layer, the first stainless steel composite fiber layer, and the first conductive fiber are symmetrically arranged on both sides of the connecting layer with the second knitted layer, the second stainless steel composite fiber layer, and the second conductive fiber.
[0008] Preferably, the inner shape of the first stainless steel composite fiber layer matches the shape of the first conductive fiber layer, both being cylindrical, and the inner side of the first stainless steel composite fiber layer and the outer side of the first conductive fiber layer are in contact with each other.
[0009] Preferably, the inner shape of the second stainless steel composite fiber layer and the shape of the second conductive fiber layer are matched, both being cylindrical, and the inner side of the second stainless steel composite fiber layer and the outer side of the second conductive fiber layer are attached to each other.
[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the components such as the first knitted layer, the first stainless steel composite fiber layer, the first conductive fiber, the connecting layer, the second knitted layer, the second stainless steel composite fiber layer, and the second conductive fiber can effectively attract and guide the diffusion of static electricity accumulated on the surface of the polyester layer, so that the static electricity is discharged and prevented from accumulating on the surface of the polyester layer. At the same time, the first knitted layer and the second knitted layer can effectively strengthen the strength of the conductive structure, and the strength of the conductive structure itself is also very good. This effectively avoids the failure of static electricity removal caused by washing, thus solving the problem that existing polyester fabrics generally use surface spraying of antistatic agents, which will gradually fall off with washing and friction. After most products are washed 10-20 times, the surface resistance will rise from 10^8Ω to more than 10^11Ω, and the antistatic effect will be basically lost. 2. In this utility model, the connection between the conductive structure and the polyester layer surface can be enhanced by the metal rod and conductive rivet head, and the static electricity can be guided to the internal conductive structure more directly, thereby further enhancing the static electricity removal effect on the polyester layer surface.

[0016] Please see Figure 1-2 This utility model provides a technical solution: A polyester fabric with an antistatic structure includes a polyester layer 1 and an antistatic coating 2. The antistatic coating 2 is fixedly connected to the top of the polyester layer 1, and a first knitted layer 3 is fixedly connected to the bottom of the polyester layer 1. A first stainless steel composite fiber layer 4 is fixedly connected inside the first knitted layer 3, and a first conductive fiber 5 is fixedly connected to the inner side of the first stainless steel composite fiber layer 4. A connecting layer 6 is fixedly connected to the bottom of the first knitted layer 3, and a second knitted layer 7 is fixedly connected to the bottom of the connecting layer 6. A second stainless steel composite fiber layer 8 is fixedly connected inside the second knitted layer 7, and a second conductive fiber 9 is fixedly connected to the inner side of the second stainless steel composite fiber layer 8. A skin-friendly layer 10 is fixedly connected to the bottom of the second knitted layer 7, and a fleece layer 11 is fixedly connected to the bottom of the skin-friendly layer 10. A metal rod 12 penetrating the polyester layer 1 and the antistatic coating 2 is fixedly connected to the top of the first stainless steel composite fiber layer 4, and a conductive rivet head 13 is fixedly connected to the top of the metal rod 12.
[0017] The conductive rivet heads 13 and metal rods 12 are grouped together, and there are several groups in total. The conductive rivet heads 13 and metal rods 12 are evenly arranged at intervals on the top of the first stainless steel composite fiber layer 4, which can effectively improve the electrostatic conduction efficiency. The first knitted layer 3, the first stainless steel composite fiber layer 4, and the first conductive fiber 5 are arranged in a left-right direction, and the second knitted layer 7, the second stainless steel composite fiber layer 8, and the second conductive fiber 9 are arranged in a front-back direction. The first knitted layer 3, the first stainless steel composite fiber layer 4, and the first conductive fiber 5 are symmetrically arranged on both sides of the connecting layer 6 with the second knitted layer 7, the second stainless steel composite fiber layer 8, and the second conductive fiber 9. This can effectively enhance conductivity. By layering, the overall strength of the conductive structure is strengthened, reducing the risk of damage. The inner shape of the first stainless steel composite fiber layer 4 matches the shape of the first conductive fiber layer 5, both being cylindrical. The inner side of the first stainless steel composite fiber layer 4 and the outer side of the first conductive fiber layer 5 are bonded together, which can effectively improve the stability of electrostatic conduction. The inner shape of the second stainless steel composite fiber layer 8 matches the shape of the second conductive fiber layer 9, both being cylindrical. The inner side of the second stainless steel composite fiber layer 8 and the outer side of the second conductive fiber layer 9 are bonded together, which can effectively improve the stability of electrostatic conduction.
[0018] Workflow: When a polyester fabric with an anti-static structure is required, the conductive rivet head 13 first conducts the static electricity on the surface of the polyester layer 1 through the metal rod 12 to the first stainless steel composite fiber layer 4, the first conductive fiber 5, the second stainless steel composite fiber layer 8, and the second conductive fiber 9. The static electricity is dispersed and discharged through the conductive mesh formed by the first stainless steel composite fiber layer 4, the first conductive fiber 5, the second stainless steel composite fiber layer 8, and the second conductive fiber 9, thus preventing the formation of static sparks on the surface of the polyester layer 1. The skin-friendly layer 10 and the fleece layer 11 can effectively improve the wearer's comfort and warmth.
