Fluorescent cocoon silk fabric prepared by using thiocyanate water solution

Abstract

The invention provides a method for preparing fluorescent silk fabrics using a thiocyanate aqueous solution, the method comprising the following steps: (1) Preparation of a solution: adding thiocyanate to water to form a thiocyanate aqueous solution, and then Phosphor powder nanoparticles are added therein, and a solution in which phosphor powder nanoparticles are dispersed is obtained under ultrasonic oscillation; (2) the silk fabric is repeatedly padded in the solution obtained in step (1); (3) after padding, The silk fabric is irradiated under microwave; (4) The irradiated silk fabric is soaked in polyvinylpyrrolidone aqueous solution to solidify, then washed and dried. 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 fluorescent powder 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 fluorescent silk fabrics by using a thiocyanate aqueous 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 fibers to the...
