Description

Technical Field

[0001] The utility model belongs to the technical field of textile fabrics, and in particular relates to an antistatic polyester base cloth. Background Art

[0002] Static electricity is formed when two materials with different dielectric constants rub against each other, and positive and negative charges accumulate on the two objects. When two objects come into contact, one tends to attract electrons from the other, so the two will form different charge potentials. As far as the human body is concerned, static electricity generated by friction between clothes and skin is one of the main reasons for the body to be charged.

[0003] In some precision manufacturing industries, static electricity can cause damage to electronic equipment and result in significant losses. Therefore, in addition to the need to install anti-static devices on the equipment, workers also need to wear anti-static clothing. The fabrics used to make anti-static clothing are usually made of polyester and conductive fibers.

[0004] The existing utility model patent with application number 202223081708 discloses an anti-static fabric and anti-static clothing, in which the anti-static fabric is prepared by plain weaving polyester fiber and carbon fiber, but its anti-static effect is insufficient. Utility Model Content

[0005] The utility model aims to solve the problem that the existing antistatic cloth described in the background technology is insufficient in antistatic effect, and proposes a new antistatic polyester base cloth, which can effectively prevent static electricity.

[0006] The technical solution adopted to achieve the above-mentioned purpose is an antistatic polyester base cloth, which includes two antistatic layers and a reinforcement layer arranged between the two antistatic layers, the antistatic layer includes a plurality of first warp yarns, a plurality of second warp yarns, a plurality of first weft yarns and a plurality of second weft yarns, the first warp yarns and the first weft yarns are interlaced and overlapped with each other to form a plain weave, a first interval is provided between adjacent first weft yarns, the second weft yarns are arranged in the first interval, a second interval is provided between adjacent first warp yarns, and the second warp yarns are arranged in the second interval.

[0007] Furthermore, the second weft yarns and the first warp yarns are interlaced and overlapped in pairs to form a plain weave.

[0008] Furthermore, the second warp yarn is interwoven with the first weft yarn and the second weft yarn in sequence in a floating and sinking or sinking and floating manner.

[0009] In the above technical solution, the second warp yarn and the second weft yarn intersect with each other, and both are conductive fibers. The intersection of the two yarns is connected to play a conductive role, and the two yarns are connected to form a mesh structure, which plays a role of electrostatic shielding.

[0010] Furthermore, the first warp yarn and the first weft yarn are composite polyester fibers, and the composite polyester fibers include polyester fibers and cotton fibers, and the cotton fibers are wound around the outer side of the circumference of the polyester fibers.

[0011] In the above technical solution, the cotton fibers are wound around the outer side of the circumference of the polyester fibers, which can enhance the elasticity of the polyester base fabric of the utility model, and the cotton fibers can reduce the generation of static electricity.

[0012] Furthermore, the spaces between the cotton fibers are filled with antistatic resin fillers.

[0013] In the above technical solution, the antistatic resin filler is mainly a mixture of the antistatic solution of the prior art and the resin, and then the resin is filled in the gaps between the cotton fibers and solidified. The resin can continuously release the antistatic solution to form a film on the fiber surface to neutralize the charge.

[0014] Furthermore, the second warp yarn and the second weft yarn are carbon black conductive fibers.

[0015] In the above technical solution, the carbon black conductive fiber can play a conductive role in conducting and dispersing electric charges, and other conductive fiber materials, such as metal conductive fibers, etc., may also be selected.

[0016] Furthermore, the reinforcing layer is a conductive metal fiber mesh, and the conductive metal fiber mesh is bonded to the second warp yarn and the second weft yarn.

[0017] Furthermore, the mesh size of the conductive metal fiber mesh is the same as the mesh size formed by the second warp yarns and the second weft yarns adjacent to each other.

[0018] In the above technical solution, the conductive metal fiber mesh mainly plays the role of connecting the upper and lower antistatic layers. The conductive metal fiber mesh can connect the second warp yarn and the second weft yarn in the upper and lower antistatic layers, so that the charge of one layer is conducted and dispersed to the other layer to prevent static electricity. The conductive metal fiber mesh has certain strength and support, thereby extending the service life of the fiber mesh.

[0019] Furthermore, the antistatic polyester base fabric also includes two adsorption soft film layers, and the adsorption soft film layers are connected to the antistatic layer.

[0020] In the above technical solution, since the carbon black conductive fibers are easily worn to produce fine particles, the adsorption soft film layer can adsorb the fine particles, thereby preventing the particles from scattering and affecting the normal operation of production equipment.

[0021] The advantages of the utility model are:

[0022] 1. The utility model is interconnected through the second warp yarn, the second weft yarn and the reinforcement layer. The second warp yarn can penetrate the surface of the antistatic layer to conduct the charges generated on both sides of the single antistatic layer, and is connected through the reinforcement layer to further reduce the generation of static electricity.

[0023] 2. The utility model is provided with an adsorption soft film layer to adsorb particles generated by the wear of the conductive fibers, thereby extending the service life of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The second warp yarn 2 is interwoven with the first weft yarn 3 and the second weft yarn 4 in sequence, that is, the second warp yarn 2 passes through the lower side / upper side of the first weft yarn 3 and the upper side / lower side of the second weft yarn 4 in sequence, and repeats continuously.
