Problems solved by technology

However, the problem with this kind of fabric is that the inorganic ultraviolet shielding agent has poor bonding ability with the fabric fibers, so the durability is poor, and the anti-ultraviolet performance is greatly reduced after repeated washing or long-term wearing.
Moreover, the dyes commonly used in the prior art are prone to change or be destroyed under sunlight, resulting in discoloration or fading due to the decomposition of the dyes.
Clothes made of anti-ultraviolet fabrics are often used in people's daily outdoor activities, so higher requirements are placed on the coolness of sunscreen fabrics. In the prior art, cool substances are often added to fabric finishing agents to achieve a cool effect on wearing , but the active ingredients are prone to failure after prolonged use or repeated washing
Therefore, it is necessary to solve the problems of fabrics with short UV resistance and coolness durability, and poor light fastness of dyed fabrics

Abstract

The invention discloses an ultraviolet-proof fabric. The ultraviolet-proof fabric is finished by an ultraviolet-proof finishing agent, wherein the ultraviolet-proof finishing agent comprises the following raw materials in parts by weight: component A: 45-55 parts of nano titanium dioxide, 1-3 parts of a silane coupling agent and 190-210 parts of water; and (B) component: 3-5 parts of cyclodextrin,2-4 parts of plant extract and 45-55 parts of water; and (3) component C: 1-2 parts of a thickening agent. Under the optimal condition, the fabric prepared by the invention shows good light fastnessbefore and after washing through a light fastness test; the ultraviolet resistance tests show that after 50 times of washing, the detergent still far meets the national standard of ultraviolet resistance products; and the cool feeling performance test shows that the mild and moderate cool feeling is displayed before washing and after 50 times of washing. The fabric prepared by the invention has excellent ultraviolet-proof function, good color fastness to light, long-acting cooling experience in the using process, simple preparation process and extremely high practical application value.

Description

technical field [0001] The invention relates to the field of fabrics, in particular to an anti-ultraviolet fabric. Background technique [0002] In recent years, due to the accelerated emission of chlorofluorocarbons due to human production, the earth's ozone protective layer has become increasingly thinner, and its ability to absorb ultraviolet radiation has been greatly weakened, resulting in a significant increase in the amount of ultraviolet rays reaching the earth's surface, which not only accelerates The aging of human skin will also harm human health in many aspects. With the acceleration of human civilization and the continuous advancement of science and technology, people's requirements for clothing have shifted from basic functions such as warmth retention and protection to multi-functional functions such as UV protection. [0003] In the prior art, an inorganic ultraviolet shielding agent is often added, and the fabric is dipped or sol-gel method is used to form ...
