Problems solved by technology

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 wool 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 wool fibers, which reduces the skin affinity of wool fibers to the human body

Abstract

The invention provides a method for preparing magnetic wool fabric by using an NMMO aqueous solution. The method comprises the following steps that (1) a dissolving solution is prepared, wherein NMMO and tris(2-carboxyethyl)phosphine are dissolved into ethyl alcohol / water (the volume ratio is 1 to 4), then magnetic nano particles are added, intense stirring is conducted, and the dissolving solution with dispersed magnetic nano particles is obtained; (2) the wool fabric is immersed into the dissolving solution obtained in the step (1) multiple times; (3) the immersed wool fabric is irradiated under microwave; (4) the irradiated wool fabric is immersed into the polyvinyl alcohol aqueous solution for solidification, then washed and dried. The method for preparing the magnetic wool fabric is low in cost and has low damage on the strength of the wool fabric, the surface performance of the wool fabric is not changed, and the magnetic nano particles have good fastness on the wool fabric; in the preparation process, no adhesive is used, and the product is non-poisonous and harmless.

Description

technical field [0001] The invention relates to a method for preparing functional fabrics, in particular to a method for preparing magnetic wool fabrics using NMMO 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 wool fibers, such as: adsorption method, sol-gel method, layer-by-layer assembly method, coating 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 wool 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 wool fibers, which reduces the skin affinity of wool fibers to the human body.
