[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] Example 1

[0015] Combine Figure 1 This embodiment is described in detail. An anti-ultraviolet polyester fabric comprises: an anti-ultraviolet fabric layer 1, a polyester base fabric layer 2, an anti-mildew fabric layer 3 and a jacquard fabric layer 4 arranged in sequence; the anti-ultraviolet fabric layer 1, the polyester base fabric layer 2, the anti-mildew fabric layer 3 and the jacquard fabric layer 4 are connected by sewing; the anti-ultraviolet fabric layer 1 is interwoven with warp yarn and weft yarn; the warp yarn is graphene polyester filament, and the weft yarn is soybean protein fiber yarn; the anti-mildew fabric layer 3 is interwoven with anti-mildew yarn; the jacquard fabric layer 4 is interwoven with cationic polyester fiber filament.

[0016] Cationic polyester filament is a polyester product spun by introducing dimethyl isophthalate with a polar group SO3Na into polyester chips. Its appearance is no different from ordinary polyester filament, but due to the use of ion modification, not only the fiber's color absorption performance is greatly improved, but also the crystallinity is reduced, making the dye molecules easier to penetrate, making the fiber easier to dye and improving the color absorption rate. Cationic polyester filament not only ensures that the cations are easy to dye, but also increases the fiber's micropores and improves the fiber's dye uptake. When dyed with cationic dyes, the fabric can have bright colors, good deep dyeing properties, high exhaustion rate (high dye uptake), and good sunlight fastness.

[0017] Furthermore, the graphene polyester filament has a fineness of 16.67 tex / 144f, while the soy protein fiber yarn has a fineness of 14.76 tex. Specifically, the graphene polyester filament is produced by melt-blending graphene powder, a dispersant, and polyester powder to form a masterbatch, which is then melt-spinned. Graphene has strong UV resistance, absorbing UV rays with wavelengths below 281nm and reflecting UV rays with wavelengths above 281nm.

[0018] The soy protein in soy protein fiber contains isoflavones and aromatic amino acids, such as tyrosine, which can absorb some UV rays. Furthermore, ZnSO4 is used as a dehydrating agent during the spinning process, and Na(OH)2 is added during the subsequent washing process, with which ZnSO4 reacts to form Zn(OH)2. Zn(OH)2 is adsorbed into the micropores of the fiber and ultimately converted into ZnO through a high-temperature drying process. These ZnO particles are firmly covalently bonded to the fiber's micropores and are not easily dislodged by washing. The ZnO particles scatter and reflect incident UV rays, thereby providing UV protection.

[0019] Furthermore, the fabric weave of the UV-resistant fabric layer 1 is an eight-pick satin. Fabric weave significantly impacts a fabric's UV resistance. Using a weave with long floats and a less pronounced float pattern can achieve excellent UV resistance. The eight-pick satin fabric has long floats and fewer warp and weft interlacing points, resulting in less UV light transmitting through the UV-resistant fabric layer 1 and excellent UV resistance.

[0020] Furthermore, the anti-mildew yarn is an antibacterial and anti-mildew modified viscose fiber yarn. Specifically, the antibacterial and anti-mildew modified viscose fiber is prepared by wet spinning a solution of a water-soluble extract of the Chinese medicinal plant litsea cubeba and fennel, and microcapsules prepared from thyme essential oil, which are blended with a viscose fiber spinning solution.

[0021] Litsea cubeba (Litsea cubeba) boasts high yields and abundant resources, with over 17 identified major chemical components, each with diverse properties and uses. Citral, the main component, accounts for over 80% of the plant's total, and possesses excellent antifungal and antibacterial properties. Fennel extract, primarily composed of anisole, aniseone, and anisaldehyde, exhibits excellent mite repellency and antibacterial properties. Thyme essential oil, primarily composed of thymol, possesses strong antifungal, antibacterial, and anti-mite properties. The active ingredients in plant extracts are primarily secondary metabolites, which can effectively kill pathogens or inhibit their growth.

[0022] Compared with ordinary viscose fiber, the antibacterial and mildew-proof modified viscose fiber has excellent antibacterial and mildew-proof properties. The antibacterial rates against Staphylococcus aureus, Escherichia coli and Candida albicans are 95.50%, 99.12% and 79.35% respectively. After 20 washings, the antibacterial rates against Staphylococcus aureus, Escherichia coli and Candida albicans are 96.00%, 91.53% and 80.43% respectively. The mildew-proof grade is 0, and the mildew-proof effect and washability are excellent.

[0023] The anti-ultraviolet polyester fabric involved in this embodiment is suitable for making curtains. When in use, one side of the anti-ultraviolet fabric layer 1 faces outdoors, and one side of the jacquard fabric layer 4 faces indoors.

[0024] Example 2

[0025] Combine Figure 2 This embodiment is described in detail. Based on the first embodiment, an anti-ultraviolet coating 5 is attached to the side of the anti-ultraviolet fabric layer 1 away from the polyester base fabric layer 2 .

[0026] Specifically, the anti-ultraviolet coating 5 is prepared by adding 60% water-based polyurethane waterproof and breathable adhesive, 10% polyethylene glycol (number average molecular weight 600), 5% silicone oil emulsion, 3% fluorine-based waterproof agent, 5% antibacterial and deodorizing finishing agent, 2% nano zinc oxide powder, 2% nano titanium dioxide powder, 3% cross-linking agent, and 10% deionized water into a reactor at one time, stirring for 30-40 minutes, and filtering to obtain an anti-ultraviolet coating glue. The anti-ultraviolet coating glue is applied to the side of the anti-ultraviolet fabric layer 1 away from the polyester base fabric layer 2, and baked at 165°C for 1.5-2 minutes to adhere to the side of the anti-ultraviolet fabric layer 1 away from the polyester base fabric layer 2.

[0027] Nano-titanium dioxide has a small size effect and has a significant light absorption effect, with a strong absorption capacity for short-wave ultraviolet rays. Nano-zinc oxide particles are much smaller than the wavelength of ultraviolet rays, scattering ultraviolet rays acting on their surface in all directions, reducing the intensity of ultraviolet rays in the direction of irradiation, thereby shielding against ultraviolet rays. Polyethylene glycol can adsorb on the surface of nano-zinc oxide particles and coat them, utilizing the steric hindrance of polymer macromolecules to prevent the nano-zinc oxide particles from agglomerating, further enhancing the fabric's UV resistance. Therefore, nano-zinc oxide powder and nano-titanium dioxide powder can achieve good UV protection with relatively small amounts. Therefore, the anti-UV coating 5 can further enhance the fabric's UV resistance.

[0028] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
