Abstract

The invention relates to a finishing method of fabric by nano-metal zinc oxide sol negative oxygen ions. The finishing method comprises the following steps: (1) dissolving zinc acetate dihydrate in ethanol, pouring strongly alkaline solution into the alcoholic solution of the zinc acetate which is cooled to the temperature of 0 DEG C, stirring at the temperature for 1.5h, and then performing ultrasonic treatment to obtain the nano-zinc oxide sol; and (2) soaking the fabric into the sol finishing agent for 3min, then predrying at the temperature of 80 DEG C, baking at the temperature for a plurality of 150s, washing and drying at the temperature. The finishing method has simple operation process and low baking temperature of 100-180 DEG C, can help realize industrial production, and overcomes the disadvantages of hard dispersion and poor stability of small particles, as well as easy conglomeration, easy migration and non-uniform distribution of the small particles on the fabric, poor binding power with the fabric, poor washing resistance, and the like.

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 zinc oxide sols of fabrics. Background technique [0002] As a newly developed material, nano-zinc oxide has shown unique properties and uses in optics, electricity, and biomedicine. It is currently mainly used in ultraviolet absorption, infrared radiation, solar cells, semiconductor gas-sensitive materials, light It is also feasible to apply catalysts and nonlinear optical materials to the functional finishing of textiles with negative oxygen ions according to the basic principles. [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 of the film on the surface of the fabric can endow the fabric with different properties, such as anti-a...
