Abstract

The invention relates to a finishing method of fabric by nano-metal titanium dioxide sol negative oxygen ions. The finishing method comprises the following steps: (1) dissolving butyl titanate in 2 / 3 of ethanol, mixing evenly, adding ethanol aqueous solution dropwise, and adjusting pH value to 2 by concentrated inorganic acid after finishing adding dropwise, and continuing to stir for 2h to obtain transparent nano-TiO2 sol, wherein, the butyl titanate, an inhibitor, an anhydrous ethanol and water are at a mol ratio of 1:1:10-30:2-4; and (2) soaking the fabric in the sol finishing agent for 3min, then predrying at the temperature of 80 DEG C, baking at the temperature of 120 DEG C for a plurality of 150s, washing and drying at the temperature of 80 DEG C. The method has simple operation process and low baking temperature of 100-180 DEG C and can help realize industrial production.

Description

technical field [0001] The invention belongs to the field of finishing nanometer metal oxide sols of fabrics, in particular to a finishing method of negative oxygen ions of nanometer metal titanium dioxide sols of fabrics. Background technique [0002] Nano-titanium dioxide is an inorganic nanomaterial with high catalytic activity and strong oxidizing ability. It has good antibacterial and self-cleaning properties, so it is widely used in antibacterial coatings, antibacterial plastics, cosmetics, textiles and medical equipment. Among them, it is used in textiles The main aspects are anti-ultraviolet radiation and antibacterial effect, but according to the basic principle, it is also feasible to apply it to the functional finishing of textiles with negative oxygen ions. [0003] Using sol-gel technology, through dipping or padding treatment, a transparent and highly adhesive nanometer metal oxide film can be formed on textiles. The type of precursor and the adsorption state ...
