Anti-ultraviolet silk fabric prepared from zinc chloride/formic acid solution

Abstract

The invention provides a method for preparing anti-ultraviolet silk fabrics using zinc chloride / formic acid solution, the method comprising the following steps: (1) Preparation of solution: adding zinc chloride to formic acid to form a concentration of 5%-20 % of the mixed solution, and then add zinc oxide nanoparticles therein, under vigorous stirring to obtain a solution dispersed with zinc oxide nanoparticles; (2) repeatedly padding the silk fabric in the solution obtained in step (1); ( 3) irradiating the padded silk fabric under microwave; (4) immersing the irradiated silk fabric in polyvinyl alcohol aqueous solution to solidify, then washing and drying. The preparation technology is simple and easy, the cost is low, the strength damage to the silk fabric is small, the surface properties of the silk fiber are not changed, and the zinc oxide nanoparticles have good fastness on the silk fabric; no adhesive is used in the preparation process, toxic free and safe.

Description

technical field [0001] The invention relates to a method for preparing functional fabrics, in particular to a method for preparing anti-ultraviolet silk fabrics by using zinc chloride / formic acid solution. Background technique [0002] Functional fiber materials can be prepared by introducing nanoparticles into textile fibers. At present, there are many preparation methods for introducing nanoparticles into silk fibers, such as: adsorption method, sol-gel method, layer-by-layer assembly method, coating method, feeding method and so on. However, the adsorption method mainly uses the intermolecular van der Waals force and ionic bond force to make the nanoparticles adsorb to the surface of the silk fiber, and the washing fastness is low; the process of the sol-gel method and the layer-by-layer assembly method is long and difficult to control; The coating method is to use adhesives to bond nanoparticles to the surface of silk fibers, which reduces the skin affinity of silk fibe...

However, the adsorption method mainly uses the intermolecular van der Waals force and ionic bond force to make the nanoparticles adsorb to the surface of the silk fiber, and the washing fastness is low; the process of the sol-gel method and the layer-by-layer assembly method is long and difficult to control; The coating method is to use adhesives to bond nanoparticles to the surface of silk fibers, which reduces the skin affinity of silk fibers to the human body; the feeding method is to mix nanoparticles into silkworm food, so that silk fibers are mixed into nanoparticles. The disadvantage is efficiency. very low
