Problems solved by technology

However, its disadvantage is that due to its photocatalytic properties, titanium dioxide, as an anti-ultraviolet material, can convert oxygen and nitrogen in the air into nitrate under the condition of light, which aggravates the increasingly serious nitrogen pollution.
However, its disadvantage is that the chemical properties of the anti-ultraviolet additives are unstable, and the anti-ultraviolet additives coated on the outer layer of the fabric are easy to corrode and fall off under the action of light and rain during use, thereby reducing its anti-ultraviolet effect.

preparation example Construction

[0024] The preparation method of above-mentioned anti-ultraviolet fabric fabric is as follows:

[0025] a Dissolve polyester particles in N-N dimethylformamide solvent in an oil bath at 50°C-80°C, stir evenly to prepare a polyester solution with a mass ratio of 1:5.

[0026] b After dissolving and stirring evenly, weigh the coffee powder according to the mass ratio of coffee powder to polyester 2:10-5:10, add it into the polyester solution and stir to make it evenly distributed, wherein the particle size of the coffee powder It is 0.5μm-5μm.

[0027] c. Apply the above-mentioned prepared mixed solution evenly on the inner layer of the fabric to form an anti-ultraviolet layer of 0.05mm-0.3mm, and leave it to dry to obtain the anti-ultraviolet fabric.

Embodiment 1

[0029] According to the above process steps: accurately weigh 10g of polyester particles and 50g of N-N dimethylformamide solvent respectively, stir and mix evenly in an oil bath at 50°C, add 5.0g of coffee powder with a particle size of 0.5μm, and stir After being uniform, it is directly coated on the inner layer of the polyester fabric to form an anti-ultraviolet layer with a thickness of about 0.3mm, and the anti-ultraviolet fabric is obtained after standing and drying.

[0030] The anti-ultraviolet performance test of this anti-ultraviolet fabric fabric shows that its ultraviolet protection factor (UPF) is 94.5, and its UVA transmittance is 3.84%, which is especially suitable for making summer sun umbrella umbrellas.

Embodiment 2

[0032] According to the above process steps: accurately weigh 10g of polyester particles and 50g of N-N dimethylformamide solvent respectively, stir and mix evenly in an oil bath at 65°C, add 4.0g of coffee powder with a particle size of 3.0μm, and stir After being uniform, it is directly coated on the inner layer of the polyester fabric to prepare an anti-ultraviolet layer with a thickness of about 0.2mm, and the anti-ultraviolet fabric is obtained after standing and drying.

[0033] The anti-ultraviolet performance test of the anti-ultraviolet fabric fabric shows that its ultraviolet protection factor (UPF) is 71.6, and the transmittance of UVA is 4.35%, which is especially suitable for making automobile sunscreen and rainproof cloth.

Abstract

The invention relates to an ultraviolet prevention fabric, including a surface layer (101), a first fabric layer (102), and a second fabric layer (103). The first fabric layer (102) covers the second fabric layer (103), and the surface layer (101) covers the first fabric layer (102). The surface layer (101) is made from carbon fibers; the first fabric layer (102) is made from mercerized wool; and the second fabric layer (103) is made from chitin fibers which are of an intersectant or random net structure. The ultraviolet prevention fabric is soft and breathable, is antistatic, and has a function of ultraviolet prevention.

Description

technical field [0001] The invention relates to an anti-ultraviolet fabric. Background technique [0002] Clothes generally refer to all kinds of clothes and clothing worn on the body. The original intention of clothes is to keep warm and protect the body; in modern society, clothes have gradually evolved into decorative items for the human body, and more often they symbolize a person's living standards and society. At the same time, on the basis that the basic functions of clothes remain unchanged, people pay more and more attention to the anti-ultraviolet effect of clothes on the body, constantly research and develop new materials for clothes, and use appropriate processes to add various functions of different materials to clothes. Among them, the functionality of the clothes is increased. [0003] Existing fabrics for producing clothes are generally made of one kind of material, and the characteristics are relatively single, especially for summer, due to the destruction ...
