NOVELTY - A copper-cobalt-nickel ferrite complex combination fastness improving method involves uniformly mixing a graphene oxide in a hydrochloric acid solution, stirring, adding aniline, dispersing, adding hydrochloric acid solution of ammonium persulfate and sealing the frozen. The frozen product is washed, filtered and dried to obtain a graphene oxide/polyaniline composite material, dissolved and dispersed in a polyethylene glycol. Ferric chloride hexahydrate, cupric chloride dihydrate, nickel sulfate hexahydrate, cobalt nitrate hexahydrate solid are added to the solution and heated. An ammonia water is added, reacted, cooled, washed, filtered and dried to obtain copper cobalt nickel ferrite/graphene oxide/polyaniline composite material, dissolved in polyurethane. The cotton fabric is fixed on the coating machine, the obtained solution is poured onto the cotton fabric, the coating machine pull rod is pulled, repeated several times, dried and baked to obtain the finished product. USE - Method for improving combination fastness of copper-cobalt-nickel ferrite complex. ADVANTAGE - The method enables improving combination fastness of copper-cobalt-nickel ferrite complex in a simple and easy manner in short time, ensuring that the prepared copper-cobalt-nickel ferrite/graphene oxide/polyaniline composite material not only has a certain photocatalytic effect on the dye wastewater, it is coated on the cotton fabric to improve the UV and electromagnetic shielding properties of the cotton fabric and improving the mechanical properties of the treated cotton fabric. DETAILED DESCRIPTION - A copper-cobalt-nickel ferrite complex combination fastness improving method involves uniformly mixing the graphene oxide in a hydrochloric acid solution, stirring under ice bath conditions, adding aniline, dispersing evenly, adding hydrochloric acid solution of ammonium persulfate, continuing the ice bath and sealing the frozen. The frozen product is washed with acetone and alcohol, filtered and dried to obtain a graphene oxide/polyaniline composite material. The graphene oxide/polyaniline composite is dissolved and dispersed in a polyethylene glycol solution. Ferric chloride hexahydrate, cupric chloride dihydrate, nickel sulfate hexahydrate, cobalt nitrate hexahydrate solid are added to the solution and heated in a water bath. An ammonia water is added, reacted at 150-200 degrees C for 2-6 hours, cooled and washed to neutrality, filtered and dried to obtain copper cobalt nickel ferrite/graphene oxide/polyaniline composite material. The copper cobalt nickel ferrite/graphene oxide/polyaniline composite material is dissolved in aqueous polyurethane solution. The cotton fabric is fixed on the coating machine, the obtained solution is slowly poured onto the cotton fabric, the coating machine pull rod is pulled for coating, repeated several times, dried and baked to obtain the anti-UV, photocatalytic and anti-electromagnetic wave versatile cotton fabric.
