Embodiment 1

[0045] An anti-ultraviolet fabric comprising a blended layer consisting of 16.3% chitosan fibers, 19.7% graphene viscose composite fibers and 64% cotton fibers.

[0046] The upper surface of the blended layer is covered with a carbon fiber-polyether polyurethane layer, the lower surface of the blended layer is covered with a crotonate-grafted starch layer, and the thickness of the carbon fiber-polyether polyurethane layer is 400 μm. The thickness of the blended layer is 0.2 cm, and the thickness of the crotonate-grafted starch layer is 600 μm.

[0047] The carbon fiber-polyether polyurethane layer is sprayed on the upper surface of the blended layer after melting the carbon fiber-polyether polyurethane at high temperature, and the crotonate-grafted starch layer is sprayed on the surface after melting the crotonate-grafted starch at high temperature. Blend layer lower surface.

[0048] The blended layer is formed by weaving cotton fibers, chitosan fibers and graphene viscose c...

Embodiment 2

[0050] A kind of anti-ultraviolet fabric of the present invention, wherein cotton fiber is through pretreatment, and the step of pretreatment is,

[0051] Step 1: Take 2.0 mL of 0.1 mol / L citric acid and 18.0 mL of 0.1 mol / L sodium citrate to prepare a citric acid-sodium citrate buffer solution with a pH of 6.4;

[0052] Step 2: soak the cotton fiber completely in the buffer solution, add hydroxycarboxylic acid to the buffer solution according to the mass ratio of cotton fiber: hydroxycarboxylic acid 1:0.04, and add hydroxycarboxylic acid to the buffer solution according to the mass ratio of cotton fiber: carboxylic acid betaine 1:0.08 Add carboxylate betaine to the solution and soak for 30 minutes;
