Method used for preparing light wool fabric from NMMO aqueous solution

Abstract

The invention provides a method used for preparing light wool fabric from NMMO aqueous solution. The method comprises following steps: 1, NMMO and tris(2-carboxyethyl)phosphine are dissolved in an ethanol / water (volume ratio 1:4) solution so as to obtain a mixed solution; 2, hollow glass bead is added into the mixed solution, and violent stirring is carried out so as to obtain a dissolving solution containing dispersed hollow glass beads; 3, wool fabric is subjected to dip padding in the dissolving solution for a plurality of times; 4, after dip padding, the wool fabric is subjected to microwave irradiation; 5, after microwave irradiation, the wool fabric is immersed in a polyvinyl alcohol aqueous solution for curing, and then water washing and drying are carried out. The method is simple and convenient; cost is low; damage on wool fabric is low; wool fiber surface performance is not changed; the fastness of the hollow glass beads on wool fabric is high; no adhesive is used in the preparation process; and the method is nontoxic.

Description

technical field [0001] The invention relates to a method for preparing functional fabrics, in particular to a method for preparing lightweight wool fabrics with 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.
