[0023] [A graphene antibacterial and heat-retaining fabric according to Embodiment 1 of this utility model]:

[0024] Please refer to Figures 1-3 This embodiment provides a graphene antibacterial and heat-retaining fabric, including a body layer 10. An antibacterial and heat-retaining component 20 is disposed on the surface of the body layer 10. The antibacterial and heat-retaining component 20 includes an antibacterial and heat-retaining layer 21, which is thermally pressed to the body layer 10. A plurality of antibacterial and heat-retaining particles are disposed on the surface and inside of the antibacterial and heat-retaining layer 21. A protective layer is disposed on the surface of the antibacterial and heat-retaining particles.

[0025] In this embodiment, the antibacterial heat storage layer 21 is composed of several polygonal coverings 22 connected together, wherein the polygons are regular hexagons. The antibacterial heat storage particles are graphene powder. The protective layer is polyurethane resin.

[0026] This utility model also provides a method for preparing graphene antibacterial and heat-retaining fabric, comprising the following steps:

[0027] S1: Add 2 parts of graphene powder to 100 parts of polyurethane resin, disperse well, and then add 0.5 parts of neutral crosslinking agent to ensure that the polyurethane resin and crosslinking agent are fully dispersed.

[0028] S2: Add 5 parts of a soft, lubricating thickener that does not affect adhesion, disperse and stir evenly to obtain the prepared graphene antibacterial heat storage slurry.

[0029] S3: Add the prepared graphene antibacterial heat storage slurry into the slurry tank of the Tieniu machine three-roll printing press, start production, and the speed is 15 meters per minute. Use the patterned roller barrel pressure knife to scrape off the excess slurry, and squeeze the material onto the prepared fabric through the rubber roller on the patterned roller. The squeezing pressure is 0.4 MPa.

[0030] S4: Oven baking, drying and curing treatment, temperature set to 135℃.

[0031] In this embodiment, a heated Teflon roller is arranged parallel to the extrusion roller to solidify the adhesion strength, thereby improving the adhesion, abrasion resistance and washability of the fabric.

[0032] The difference between Comparative Example 1 and Example 1 is that in this example, graphene antibacterial and heat-retaining fabric with an equal amount of polyurethane resin protective layer is used instead of the graphene fiber obtained by prior art in Example 1.

[0033] Performance testing: The relevant properties of the graphene fabric products provided in Example 1 and Comparative Example 1 were tested respectively, and the experimental data obtained are recorded in the table below:

[0034]

[0035] [A graphene antibacterial and heat-retaining fabric according to Embodiment 2 of this utility model]:

[0036] Please refer to Figure 4 In this embodiment, the body layer 10 includes a surface layer 11, an intermediate layer 12 and a bottom layer 13 distributed from top to bottom. The surface and bottom of the intermediate layer 12 are provided with antibacterial heat storage components 20. The surface layer 11, the bottom layer 13 and the intermediate layer 12 are connected by hot pressing.

[0037] In this embodiment, during the preparation process, an intermediate layer 12 with an antibacterial heat storage component 20 is first prepared, and then the surface layer 11, the intermediate layer 12 and the bottom layer 13 are hot-pressed together by a hot-pressing process.

[0038] This invention incorporates graphene powder into a graphene antibacterial fabric. Graphene achieves antibacterial properties through a triple mechanism: physical cutting (such as nanoscale sharp edges that directly pierce bacterial cell membranes), oxidative stress generating reactive oxygen species that destroy bacterial biomolecules, and encapsulation and isolation that blocks bacterial metabolism. This results in highly efficient antibacterial properties for the fabric. Furthermore, graphene's high thermal conductivity allows it to rapidly absorb and release heat, giving the fabric excellent heat storage capacity. When made into clothing and other products, it effectively maintains stable body surface temperature.

[0039] This invention improves the dispersibility of graphene by setting a polyurethane resin protective layer on the surface of graphene powder, thereby preventing agglomeration, enhancing its mechanical properties, and significantly improving its corrosion resistance and wear resistance, making it wear-resistant and washable.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
