Problems solved by technology

The main component of wool fiber is α-keratin. Keratin molecules form a highly cross-linked three-dimensional stable structure through disulfide bonds, hydrogen bonds, salt bonds and other bonds. Dissolution, the traditional method of dissolving wool protein is to break the disulfide bond or peptide bond of the protein molecule into short peptides by strong alkali, strong acid, reducing agent or oxidizing agent and other reagents. These methods generally have a large amount of inorganic acid, alkali, reducing agent or oxidizing agent The waste of environmentally unfriendly solvents has a serious impact on the environment

Abstract

The invention relates to a preparation method of an ITO (indium tin oxide) / wool keratin solution compound functional finishing agent. The method comprises the following steps: 1) washing wool fibers with water, cleaning with detergent, degreasing with ethanol-acetone mixed solvent, crushing and adding into ion liquid, and heating and stirring to obtain a keratin ion liquid solution; 2) preparing an acetylacetone solution of indium trichloride and an ethanol solution of tin tetrachloride, and mixing the two solutions to obtain indium tin metal oxide sol; and 3) adding the indium tin metal oxide sol into the keratin ion liquid solution obtained in the step 1), and stirring and mixing to obtain the ITO / wool keratin solution compound functional finishing agent. The method provided by the invention can use fibers such as waste wool, cashmere and the like as raw materials, and is low in cost, simple to operate and easy to realize industrial production; and the compound functional finishing agent prepared by the method has the photoelectric properties such as high visual light transmissivity, high ultraviolet absorptivity, low resistivity and the like.

Description

technical field [0001] The invention belongs to the field of preparation of composite functional finishing agents, in particular to a preparation method of an ITO / wool keratin solution composite functional finishing agent. Background technique [0002] Wool keratin fiber is one of the earliest natural fiber materials used by human beings. Due to the limitation of wool quality and textile technology, a large number of short fibers and thick fibers are discarded every year, making the research on the regeneration and utilization of this kind of fibers and methods continue. for people's attention. The main component of wool fiber is α-keratin. Keratin molecules form a highly cross-linked three-dimensional stable structure through disulfide bonds, hydrogen bonds, salt bonds and other bonds. Dissolution, the traditional method of dissolving wool protein is to break the disulfide bond or peptide bond of the protein molecule into short peptides by strong alkali, strong acid, reduc...
