Problems solved by technology

and CeO 2 The catalytic activity is low, and the preparation of anti-ultraviolet fabrics by combining nano-cerium oxide with fabrics has a bright prospect
[0003] Using nanoparticles as additives to modify the base material of clothing fabrics to obtain a series of excellent composite fibers with different functions is the main method to develop new chemical fiber products. At present, the main methods of research on anti-ultraviolet fabrics are: coating method, emulsion finishing method, resin finishing method, etc. These methods cannot chemically combine the anti-ultraviolet material and the fabric, so that the combination of the anti-ultraviolet material and the fabric is not firm. As the number of washings increases, the anti-ultraviolet performance will be reduced, and the hand feel of the fabric , poor whiteness etc.

Description

technical field [0001] The invention belongs to the technical field of post-treatment of fabrics, and in particular relates to a nano-ultraviolet shielding agent and its preparation method and application. Background technique [0002] In recent years, due to the increasingly serious damage to the ozone layer, the intensity of ultraviolet rays reaching places has increased, resulting in an increase in the prevalence of skin cancer, cataracts and other diseases. Scientists have analyzed that if the concentration of the ozone layer decreases by 10%, the incidence of skin cancer will increase by 26%, and the world will also decline. There are 1.6-1.75 million new cataract patients, so higher requirements are placed on the UV resistance of fabrics. Traditional organic ultraviolet absorbers and new inorganic nano-ultraviolet shielding agents are the core part of improving the anti-ultraviolet properties of fabrics. New nanomaterials can strongly shield ultraviolet rays under the ...
