Abstract

The present invention relates to a method for preparing magnetic-induced discoloration polymeric fibers. The method comprises: adopting ferrocene, acetone, and hydrogen peroxide as starting raw materials; adopting a solvothermal method to prepare ferroferric oxide nanospheres; dispersing the ferroferric oxide nanospheres into an acetone solvent to obtain a dispersion liquid; uniformly mixing the dispersion liquid and polyethylene glycol diacrylate (PEGDA); evaporating the acetone solvent; adding an ultraviolet light initiator to obtain a polymer monomer emulsion (Fe3O4 / PEGDA); and placing polymer fibers in a magnetic field, and adopting an ultraviolet light polymerization method to polymerize the Fe3O4 / PEGDA on the surfaces of the polymer fibers to obtain the magnetic-induced discoloration polymeric fibers. The structural color fibers prepared by the method of the present invention have excellent optical properties, and can be used for preparation of magnetic field regulated photonic crystal fibers, photonic crystal sensors, and the like. The method of the present invention has characteristics of simple operation, good effect, and no requirement of chemical dyes, and provides important reference values for reduction of environmental pollution on dyeing and finishing industry.

Description

technical field [0001] The invention belongs to the field of polymer fiber preparation, in particular to a method for preparing magnetochromic polymer fibers. Background technique [0002] The traditional dyeing process of fibers used in textile materials is to use organic or inorganic dyes to chemically or physically combine with fibers, or to generate insoluble colored substances on fibers, but there are a lot of heavy metal ions and toxic substances in the dye preparation and dyeing process. intermediates, which have serious negative impacts on humans and the environment. For this reason, in all countries in the world, paying attention to dye production and emphasizing environmental protection has become a top priority. The United States, Europe, and Japan have established institutions to study the ecological safety and toxicology of dyes, specializing in understanding and researching the impact of dyes on human health and the environment. And developed heavy metal conte...
