[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention uses anti-ultraviolet fiber blended yarn as the weft of the textile fabric, and at the same time, anti-ultraviolet fiber is blended into the anti-ultraviolet fiber blended yarn, so that the textile fabric can still maintain a high anti-ultraviolet ability after being washed many times. The anti-ultraviolet fiber is prepared from polyvinyl alcohol as a raw material, and a thickener is also added in the preparation of the anti-ultraviolet fiber to improve the adhesion ability of the anti-ultraviolet additive. The addition of the anti-ultraviolet additive in the anti-ultraviolet fiber enables the fabric to absorb and block ultraviolet rays to a certain extent, thereby improving the anti-ultraviolet performance of the textile fabric.

[0028] 3. The present invention adds polyester fiber to the blended warp yarn of the textile fabric and uses polyester fiber to prepare antibacterial fiber. Polyester fiber has high strength and elastic recovery ability, so that the textile fabric has good wear resistance and abrasion resistance. At the same time, the fabric is only woven by warp and weft threads without adhering other textile fabric layers, so that the textile fabric has excellent wear resistance while remaining light and thin.

[0029] 4. The present invention uses mulberry silk and natural cotton fiber as part of the blended raw materials in the warp, and uses modal fiber as one of the blended raw materials in the weft. Mulberry silk, natural cotton fiber and modal fiber have strong moisture absorption properties and soft hand feel, making the textile fabric very comfortable. DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] An embodiment of the present invention provides a textile fabric with an anti-ultraviolet function. The textile fabric is made by interweaving warps and wefts perpendicularly to each other. The warps are yarns blended according to weight parts of 5 to 8 parts of mulberry silk, 2 to 6 parts of natural cotton fibers, 4 to 6 parts of polyacrylonitrile fibers, and 3 to 5 parts of polyester fibers. The wefts are blended yarns of anti-ultraviolet fibers. The diameter of the warps is 42.5 to 45.5 microns, the diameter of the wefts is 50.2 to 54.5 microns, the density of the warps is 65 to 70 strands / cm, and the density of the wefts is 55 to 62 strands / cm.

[0032] The anti-ultraviolet fiber blended yarn is blended from anti-ultraviolet fiber, antibacterial fiber, modal fiber and polyester fiber. The weight ratio of the components for preparing the anti-ultraviolet fiber blended yarn is 28wt% to 32wt% of antibacterial fiber, 12wt% to 18wt% of modal fiber and 8wt% to 15wt% of polyester fiber, and the balance is anti-ultraviolet fiber.

[0033] Among them, mulberry silk is a hollow fiber structure with countless pores, which can help ventilation. The silk protein on its outside can absorb environmental moisture and human metabolites, keep dry and comfortable, and avoid bacterial growth. The tyrosine, tryptophan, phenylalanine, etc. in mulberry silk sericin can effectively absorb ultraviolet rays and protect the skin from damage. At the same time, mulberry silk is relatively soft and has a high sense of comfort as a clothing fabric. Natural cotton fiber is a natural fiber with good moisture absorption, good air permeability and wear resistance. The fabrics made from it are highly skin-friendly.

[0034] Polyacrylonitrile fiber is an excellent UV-proof fiber. The -CN group in its structure can absorb UV energy and convert it into heat energy for dissipation, so very little energy is conducted into the fiber, which can play a role in UV protection. Polyester fiber has high strength and elastic recovery ability, good wear resistance and abrasion resistance, is not easy to wrinkle, and has good shape retention.

[0035] Modal fiber is made of natural wood pulp, has a soft and smooth feel, is highly hygroscopic, and is biodegradable, making it environmentally friendly.

[0130] In step S1, polyacrylonitrile fiber and mulberry silk of equal weight are twisted in a spiral shape to obtain blended yarn A, polyester fiber and natural cotton fiber of equal weight are twisted in a spiral shape to obtain blended yarn B, and the remaining UV-resistant fiber raw material and blended yarn A and blended yarn B are twisted in a spiral shape to obtain blended warp yarn;

[0131] In step S2, modal fiber and anti-ultraviolet fiber of equal weight are twisted in a spiral shape to obtain a blended yarn C, polyester fiber and anti-ultraviolet fiber of equal weight are twisted in a spiral shape to obtain a blended yarn D, and the remaining anti-ultraviolet fiber raw material and the blended yarn C and the blended yarn D are twisted in a spiral shape to obtain a blended weft yarn.

[0132] The textile fabric and preparation method of this comparative example are different from those of Example 1 in that the weft uses the same blended yarn as the warp, and in the subsequent preparation method, there is no need to prepare antibacterial fiber or blend the antibacterial fiber, and the rest are the same as in Example 1.

[0133] In the above embodiments and comparative examples, the weight ratios of the components of the warp and weft of the textile fabric are as follows:

[0135] UV protection performance test:

[0136] The anti-ultraviolet performance of the textile fabric samples obtained in the embodiment and the comparative example was tested with reference to GB / T18830-2009 standard. The test results were expressed in UPF, i.e., ultraviolet protection factor. The higher the UPF value, the higher the anti-ultraviolet performance of the sample.

[0137] The results of the UV protection performance test are as follows:

[0138]

[0139] Antibacterial performance test:

[0140] The antibacterial performance of the textile fabric samples obtained in the examples and comparative examples was tested according to the test method in the reference standard FZ / T 01021-1992 "Test Method for Antibacterial Performance of Fabrics". This test was mainly aimed at Staphylococcus aureus and Candida albicans;

[0141] The antibacterial performance test results are as follows:

[0142]

[0143] Combined with the above implementation and comparative examples, and combined with the test results for analysis:

[0144] By comparing Examples 1-4 with Comparative Example 1, the anti-ultraviolet performance of the textile fabric samples of Examples 1-4 is significantly better than that of the textile fabric sample of Comparative Example 1;

[0145] By comparing Examples 1-4 with Comparative Example 2, the antibacterial effects of the textile fabric samples of Examples 1-4 on Escherichia coli and Staphylococcus aureus are significantly better than those of the textile fabric sample of Comparative Example 2.

[0146] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
