Abstract

An anti-ultraviolet finishing liquid for fabric is prepared from tetrabutyl titanium, organic solvent, hydrochloric acid, acetic acid and water. It can be used to prepare the anti-ultraviolet fabric through preparing TiO2 sol and using it to finish the fabric for generating the TiO2 gel nanoparticles on the surface of fabric.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a sol-gel anti-ultraviolet method for polyester fabrics. Background technique [0002] The basic principle of sol-gel technology is to hydrolyze metal alkoxide or inorganic salt directly or form a sol through degelation, then gel the solute, then dry and bake the gel to remove organic components, and finally obtain inorganic materials . At present, it is mainly used in the preparation of glass, ultra-fine powder and thin film. It needs to be fired at a high temperature of 300-800 ° C. When making the film, the smooth surface of glass, metal, plastic, etc. is used as the substrate for coating, and a continuous film is formed on the surface of the substrate. , The combination between the membrane and the carrier is by van der Waals force, and there is no chemical combination. It is unrealistic to use such a process on textiles, because textiles cannot withst...
