Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. The embodiments of this utility model are described below with reference to the accompanying drawings.

[0011] like Figures 1-4 As shown, an antistatic polyester fabric includes an antistatic layer 1 and an adsorption layer 2. The antistatic layer 1 is formed by interlacing and mixing a plurality of first warp yarns 5, a plurality of second warp yarns 6, a plurality of first weft yarns 3, and a plurality of second weft yarns 4. The first warp yarns 5 and second warp yarns 6 are alternately arranged, and the first weft yarns 3 and second weft yarns 4 are alternately arranged. The first warp yarns 5 and first weft yarns 3 are graphene-modified polyester composite fibers, including polyester fibers 11, cotton fibers 13, and graphene filler 12 with a mass fraction of 5-10%. The second warp yarns 6 and second weft yarns 4 are graphene-coated conductive fibers. The adsorption layer 2 is a photoresponsive self-cleaning soft film, which includes titanium dioxide nanoparticles and is directly connected to the antistatic layer 1.

[0012] Specifically, the antistatic layer 1 is a fabric formed by interlacing and mixing several first warp yarns 5, several second warp yarns 6, several first weft yarns 3, and several second weft yarns 4. The first warp yarns 5 and the first weft yarns 3 are both graphene-modified polyester composite fibers, which include polyester fibers 11, cotton fibers 13, and graphene filler 12 with a mass fraction of 5-10%. The second warp yarns 6 and the second weft yarns 4 are graphene-coated conductive fibers. Compared with the existing technology, the surface resistance of the graphene-modified fibers and graphene-coated conductive fibers is reduced, and the conductivity is improved. The adsorption layer 2 is a photoresponsive self-cleaning soft film. The photoresponsive self-cleaning soft film provides active protection with an antibacterial rate of ≥99% against E. coli and a UV blocking rate of ≥95%. It can be extended to medical and outdoor equipment. It contains titanium dioxide nanoparticles, which will activate and decompose pollutants under ultraviolet irradiation.

[0014] Specifically, in the graphene-coated conductive fiber, the matrix fiber 7 can be polyester filament, nylon 6, or aramid, which can be selected according to the application scenario. A dry process can be selected to form a catalytic copper / nickel layer, i.e., the interface transition layer 8, on the matrix fiber 7 by magnetron sputtering. Then, a graphene layer 9 is formed by chemical vapor deposition. The thickness of the graphene layer 9 can be 0.1-0.5μm. The hydrophobic protective layer 10 can be made of fluorinated silica sol.

[0015] In some embodiments, the graphene-modified polyester composite fiber includes cotton fiber 13 and polyester fiber 11, with cotton fiber 13 wound around the outer circumference of polyester fiber 11, and graphene filler 12 filling the space between cotton fiber 13 and polyester fiber 11.

[0016] Specifically, polyester fiber 11 is polyester filament, nylon 6 or aramid. A graphene dispersion is prepared, including graphene, waterborne polyurethane, dispersant, ethylene glycol and deionized water. After mixing, the mixture is ultrasonically crushed, ball-milled and centrifuged to form a liquid. Then, the above-mentioned polyester fiber 11 is immersed in the above-mentioned graphene dispersion and dried to form the graphene dispersion.

[0017] In some embodiments, silver ions are added to the adsorption layer 2 at a mass fraction of 1-3% for synergistic antibacterial purposes.

[0018] Specifically, the mass fraction of silver ions in the adsorption layer 2 is 1% or 3%, or even 2%. Silver ions have antibacterial properties, which enhance the antibacterial performance of the fabric.
