Magnetic wool fabric prepared by using inorganic sulfur-containing reductive agent

Abstract

The present invention provides a method for preparing magnetic wool fabrics using an inorganic sulfur-containing reducing agent, the method comprising the following steps: (1) Preparation of a solution: dissolving the inorganic sulfur-containing reducing agent, urea and sodium lauryl sulfate into water, then add magnetic nanoparticles, stir vigorously to prepare a solution in which magnetic nanoparticles are dispersed; (2) pad the wool fabric in the solution obtained in step (1) for several times; (3) pad the The woolen fabric is heated under hot air; (4) The heated woolen fabric is soaked in saturated sodium chloride aqueous solution to solidify, then washed and dried. The preparation technology is simple and easy, the cost is low, the strength damage to the wool fabric is small, the surface properties of the wool fiber are not changed, and the magnetic nanoparticles have good fastness on the wool fabric; no adhesive is used in the preparation process, and no Poison is 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 by using an inorganic sulfur-containing reducing agent. 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 hum...
