Problems solved by technology

However, the above two methods have obvious disadvantages: First, because the preparation conditions of nanomaterials are relatively harsh, and the finishing process is relatively complicated, and the finishing time is long, it is difficult to meet the requirements of large-scale production. Currently, widely used nanomaterials, such as TiO 2 , ZnO, Ag, the yields are all small; secondly, the nanomaterial particles are small, the specific surface area is large, and agglomeration easily occurs on the surface and inside of the fabric, and the agglomeration of nanoparticles will be accelerated during drying, even if the surface is modified. It is more difficult to solve this problem; moreover, because the nanoparticles are inorganic materials and there are no organic groups on the surface, it is difficult to chemically react with the fabric to form a firm bond; and after the surface of the nanoparticles is modified, the surface of the particles is wrapped by organic matter , will have an impact on its properties, especially the unique properties of nanomaterials in terms of antibacterial and antistatic
Therefore, nanomaterials are still facing great challenges in fabrics and other applications in actual production.

Abstract

The invention discloses a method for preparing anti-UV fabric by an in-situ method, belonging to the technical field of fabric post treatment. The method includes the steps of: weighing Ce (NO3)3.6H20, dissolving the Ce (NO3)3.6H20 in water, stirring to enable the Ce(NO3)3.6H20 to dissolve evenly so as to prepare Ce(NO3)3 solution with concentration of 1-5g / L; and adding a surfactant, aqueous ammonia and a strong oxidizer into the Ce(NO3)3 solution sequentially, stirring to be even, soaking the fabric in the solution for 10-120mins, taking out the fabric, and drying for 1-5mins at 80-180 DEG C. In this way, washable anti-UV fabric can be prepared. The weight ratio of the Ce (NO3)3.6H20, the surfactant, the aqueous ammonia and the hydrogen peroxide is 10:5-24:1-9:1-5; and the surfactant iscetyl-trimethyl ammonium bromide or dodecyl benzene sulfonic acid sodium salt. The method is simple in process and low in cost, and through the method, anti-UV fabric which can be tightly bonded withnanometer material can be prepared.

Description

technical field [0001] The invention belongs to the technical field of post-treatment of fabrics, and in particular relates to a method and application of an in-situ method for preparing anti-ultraviolet fabrics 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 unde...
