Description

Technical Field

[0001] This utility model relates to the field of knitted fabric technology, and in particular to an antistatic polyester fabric. Background Technology

[0002] Antistatic polyester fabrics are widely used in the electronics industry, medical protection, and special work clothes. Their core function is to suppress or quickly dissipate static electricity accumulation, preventing equipment damage or safety accidents caused by electrostatic discharge. Traditional antistatic polyester fabrics often achieve charge conduction by adding conductive fibers (such as carbon fiber or metal fiber) or surface coatings (such as antistatic agents). However, due to limitations such as poor material dispersion and a single conductive path, their performance is prone to degradation due to mechanical wear or repeated washing over long-term use.

[0003] In existing technologies, the design of antistatic polyester fabrics often suffers from a lack of multi-dimensional synergistic conductivity, as the conductive mesh structure is mostly planar and unidirectional. Static charges cannot diffuse rapidly through the three-dimensional network, leading to localized charge accumulation. The bonding methods between the conductive material and the matrix fibers are limited (e.g., simple blending or lamination), making it difficult to form continuous low-resistance pathways. Furthermore, the structure is not optimized for different stress directions (e.g., lack of honeycomb reinforcement or diagonal cross-weaving), causing the conductive paths to easily break under dynamic stretching or friction conditions. The surface antistatic layer relies on high-density metal fiber weaving, which, while achieving electrostatic equalization, results in excessive stiffness and poor breathability, sacrificing the flexible wearing characteristics of the polyester fabric. Therefore, we provide an antistatic polyester fabric. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an antistatic polyester fabric.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an antistatic polyester fabric, comprising: an outer weaving mechanism, the outer weaving mechanism comprising polypropylene fibers, on which silver fibers are transversely intersected; an inner embedding mechanism provided on the bottom side of the outer weaving mechanism, the inner embedding mechanism comprising carbon black fibers, on which nylon fibers are longitudinally intersected; an inner sleeve mechanism provided on the side of the inner sleeve mechanism away from the outer weaving mechanism, the inner sleeve mechanism comprising carbon fiber filaments, on which conductive polyester fibers are transversely intersected; and a contact mechanism provided on the side of the inner sleeve mechanism away from the inner embedding mechanism, the contact mechanism comprising polyester fibers, on which antistatic fibers are longitudinally intersected.

[0006] In a preferred embodiment, the outer weaving mechanism, the inner embedding mechanism, the inner sleeve mechanism, and the contact mechanism are interwoven in a multi-dimensional manner using nanofiber filaments and graphene composite threads during interlayer stitching.

[0007] In a preferred embodiment, the diameter of both the nanofiber filaments and the graphene composite thread is 0.4-0.6 mm. The nanofiber filaments are zigzag-stitched with 0.25 mm platinum needles at 2 mm intervals in the warp direction. The graphene composite thread is woven with 0.25 mm platinum needles at a 45° oblique angle in the weft direction between the nanofiber filament stitches to form a honeycomb-like reinforced structure.

[0008] In a preferred embodiment, the polypropylene fibers and silver fibers of the outer weaving mechanism are formed into a surface antistatic mesh using a double-helix loop weaving method with 0.8mm tungsten steel needles, and the weaving density is 12×12 warp and weft nodes per square centimeter.

[0009] In a preferred embodiment, the carbon black fibers and nylon fibers of the embedded mechanism are woven in a sandwich structure using 0.6mm titanium alloy needles. The carbon black fibers are arranged in parallel at a spacing of 0.2mm in the X-axis direction, and the nylon fibers are interlaced vertically at a spacing of 0.3mm in the Y-axis direction to form an electromagnetic shielding layer.

[0011] In one preferred embodiment, the antistatic fibers of the contact mechanism are woven into a polyester fiber substrate with micron-level pores using 0.5mm silver needles, and antistatic nano-protrusions are formed on the fabric surface using a three-dimensional interlacing process. The protrusions have a height of 50-80μm and a distribution density of 120-150 per square millimeter.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention utilizes multi-dimensional interlacing weaving of nanofiber filaments and graphene composite threads to significantly enhance the antistatic synergistic effect of the fabric. The nanofiber filaments are interlaced and stitched in a Z-shape with a warp spacing of 2mm using 0.25mm platinum needles to form directional charge conduction channels. The graphene composite threads are interwoven at a 45° angle between the nanofiber filament rows to form a honeycomb-like reinforcement structure. The three-dimensional conductive network accelerates the dissipation of static charge. The double-helix antistatic mesh of the outer weave structure achieves surface electrostatic equalization through 12×12 warp and weft nodes of silver fiber and polypropylene fiber. The 45° conductive mesh structure of the inner sleeve structure allows conductive polyester fibers to wrap carbon fiber filaments at 5mm intervals, forming a continuous low-impedance conductive path.

[0028] Example 1

[0029] like Figure 1-4 As shown, this utility model provides a technical solution: an antistatic polyester fabric, comprising: an outer weaving mechanism 1, the outer weaving mechanism 1 including polypropylene fibers 11, silver fibers 12 intersecting transversely on the polypropylene fibers 11, an inner embedding mechanism 2 provided on the bottom side of the outer weaving mechanism 1, the inner embedding mechanism 2 including carbon black fibers 21, nylon fibers 22 intersecting longitudinally on the carbon black fibers 21, an inner sleeve mechanism 3 provided on the side of the inner sleeve mechanism 2 away from the outer weaving mechanism 1, the inner sleeve mechanism 3 including carbon fiber filaments 31, conductive polyester fibers 32 intersecting transversely on the carbon fiber filaments 31, and a contact mechanism 4 provided on the side of the inner sleeve mechanism 3 away from the inner embedding mechanism 2, the contact mechanism 4 including polyester fibers 41, antistatic fibers 42 intersecting longitudinally on the polyester fibers 41;

[0030] The outer weaving mechanism 1, the inner embedding mechanism 2, the inner sleeve mechanism 3, and the contact mechanism 4 are interwoven in a multi-dimensional manner using nanofiber filaments and graphene composite threads during interlayer stitching;

[0031] Both the nanofiber filaments and the graphene composite thread have a diameter of 0.4-0.6 mm. The nanofiber filaments are zigzag stitched with 0.25 mm platinum needles at 2 mm intervals in the warp direction. The graphene composite thread is woven with 0.25 mm platinum needles at a 45° oblique angle in the weft direction between the nanofiber filament stitches to form a honeycomb-like reinforced structure.

[0032] The polypropylene fiber 11 and silver fiber 12 of the outer weaving structure 1 are formed into a surface antistatic mesh by using 0.8mm tungsten steel needles through a double helix winding weaving method, with a weaving density of 12×12 warp and weft nodes per square centimeter;

[0033] The carbon black fiber 21 and nylon fiber 22 of the embedded mechanism 2 are woven in a sandwich structure using 0.6mm titanium alloy needles. The carbon black fiber 21 is arranged in parallel with a spacing of 0.2mm in the X-axis direction, and the nylon fiber 22 is interwoven vertically with a spacing of 0.3mm in the Y-axis direction to form an electromagnetic shielding layer.

[0034] The carbon fiber filaments 31 and conductive polyester fibers 32 of the inner mechanism 3 are made of 0.7mm diamond-coated needles and are woven in a multi-axial 45° interlaced manner to form a conductive mesh structure. The conductive polyester fibers 32 wrap the carbon fiber filaments 31 at 5mm intervals to form a continuous conductive path.

[0035] The antistatic fiber 42 of the contact mechanism 4 is woven into the polyester fiber 41 substrate with micron-level pores by 0.5mm silver needles. The antistatic nano-protrusions are formed on the fabric surface by a three-dimensional interlacing process. The height of the protrusions is 50-80μm and the distribution density is 120-150 per square millimeter.

[0036] In this embodiment, the antistatic synergistic effect of the fabric is significantly enhanced by using multi-dimensional interlacing weaving of nanofiber filaments and graphene composite threads. The nanofiber filaments are interlaced and stitched in a Z-shape with a warp spacing of 2mm using 0.25mm platinum needles to form directional charge conduction channels. The graphene composite threads are interwoven at a 45° oblique angle between the nanofiber filament rows to form a honeycomb-like reinforcement structure. The three-dimensional conductive network accelerates the dissipation of static charge. The double-helix antistatic mesh of the outer weaving mechanism 1 achieves surface electrostatic equalization through the weaving of silver fiber 12 and polypropylene fiber 11 at 12×12 warp and weft nodes. The 45° conductive mesh structure of the inner mechanism 3 allows conductive polyester fiber 32 to wrap carbon fiber filament 31 at 5mm intervals, forming a continuous low-impedance conductive path. The antistatic fiber 42 of the contact mechanism 4 is woven through micron-level pore filling, forming 120-150 pores / mm on the surface. 2 The nano-protrusions actively neutralize the static electricity buildup on the contact surface through the tip discharge effect.

[0037] Working principle:

[0038] like Figure 1-4As shown, in the outer layer structure of the fabric (outer weaving structure 1), the double-helix antistatic mesh is woven with silver fibers 12 and polypropylene fibers 11 using 12×12 warp and weft nodes. This design effectively achieves surface electrostatic equalization, uniformly distributes charges, and prevents localized static accumulation. Furthermore, in the inner layer structure of the fabric, a 45° conductive mesh structure is used, where conductive polyester fibers 32 wrap around carbon fiber filaments 31 at 5mm intervals, forming a continuous low-impedance conductive path, thereby further reducing the overall resistance of the fabric and improving static dissipation efficiency.

[0039] For the directly contacted parts, the antistatic fiber 42 is woven through micron-level pore filling, creating dense nano-protrusions on the fabric surface, approximately 120-150 per mm. 2 These nanoscale protrusions can actively neutralize the static electricity buildup on the contact surface through the tip discharge effect, effectively reducing the impact of static electricity on the human body or precision equipment and improving protective performance.

[0040] This weaving technology not only optimizes the electrostatic discharge path but also enhances the overall antistatic capability of the fabric through multi-layered and multi-structured synergistic effects, providing an efficient and reliable electrostatic protection solution for fields such as industrial protection, precision electronic operation, and medical devices. Workers use nanofiber filaments and graphene composite threads for multi-dimensional interlacing weaving, effectively enhancing the fabric's antistatic synergistic effect. Specifically, the nanofiber filaments are zigzag-stitched along the warp direction with 0.25mm platinum needles at 2mm intervals, constructing directional charge conduction channels that allow static charges to be rapidly conducted and released along a predetermined path. Simultaneously, between the nanofiber filaments, graphene composite threads are interwoven at a 45° oblique angle to form a honeycomb reinforcement structure, which not only improves the overall stability of the fabric but also significantly accelerates static charge dissipation through a three-dimensional conductive network, reducing the risk of charge accumulation.

[0041] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0042] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
