Problems solved by technology

The fabric has good air permeability, good comfort and good UV resistance. Although it has a certain UV resistance, it is specially equipped with an UV-resistant layer, resulting in poor flexibility of the fabric. It is not suitable for casual clothing fabrics, nor does it have Antistatic and antibacterial properties

Abstract

The invention discloses a preparation method of an anti-ultraviolet textile fabric. The method is characterized by comprising the following steps of S1, preparing an anti-ultraviolet functional copolymer; S2, preparing an epoxy modified anti-ultraviolet functional copolymer; S3, preparing anti-ultraviolet fibers; and S4, weaving the fabric. The invention further provides the anti-ultraviolet textile fabric prepared according to the preparation method of the anti-ultraviolet textile fabric. The anti-ultraviolet textile fabric provided by the invention is remarkable in anti-ultraviolet effect, good in air permeability and antistatic and antibacterial properties, strong in fastness to washing, and good in wearing comfort and durability.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to an anti-ultraviolet textile fabric and a preparation method thereof. Background technique [0002] With the development of science and technology and the improvement of living standards, people's self-protection awareness has been continuously strengthened, and the requirements for additional functions of clothing have become higher and higher. Ultraviolet light is a very important physical factor in nature, and it is an indispensable factor for various organisms to maintain normal metabolism. However, excessive ultraviolet radiation will cause harm to the human body. It can penetrate into the dermis to promote the production of melanin in the human skin and promote human skin aging; it can also cause sunburn, causing erythema and blisters on the skin; more seriously, it can cause skin cancer. It is one of the simplest and most effective ways to avoid UV damage and prote...
