Gel-sol antibacterial agent and its preparation and application

Abstract

By means of sol-gel technology, the present invention prepares titanium-containing sol with tetrabutyl titanium as precursor. The sol is used in finishing cotton fabric through rolling-stoving-roasting process, and sol treated cotton fabric has excellent lasting antibiotic performance and negative ion releasing effect. The treating process has no side effect on the hand feeling and strength of the fabric.

Description

technical field [0001] The invention relates to an antibacterial treatment agent for cotton fabrics, in particular to a sol-gel antibacterial treatment agent for cotton fabrics, a preparation method and application thereof. Background technique [0002] The basic principle of sol-gel technology is to hydrolyze metal alkoxides or inorganic salts directly or form sols through degelation, then gel the solutes, then dry and bake the gels to remove organic components, and finally obtain inorganic materials . [0003] At present, it is mainly used in the preparation of glass, ultra-fine powder and 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, forming a continuous coating on the surface of the substrate. The membrane, the membrane and the carrier are combined by van der Waals force, and there is no chemical combination. [0004] It is unrealistic to use...

AI Technical Summary

Problems solved by technology

[0004] It is unrealistic to use the above process on textiles, because textiles cannot withstand high temperature roasting

[0005] The use of nanotechnology to endow fabrics with special functions is a newly developed technology, which is still in the exploratory stage, such as adding nano-TiO in the spinning process 2 , SiO 2 , Sb 2 o 3 , ZnO and other particulate textile fibers, or nano-TiO 2 , SiO 2 , Sb 2 o 3 , ZnO and other particles are dispersed in the coating agent to coat textiles, etc., endowing the fabric with special properties such as UV resistance, antibacterial, flame retardant, etc., but there are still some problems to be solved, such as the dispersion of nanoparticles, nano The combination and fastness of the particles in the fabric, the effect of the addition of nanoparticles on the physical and chemical properties of the fibers and the fabric itself, etc.
