Material for producing macromolecule air fibers, preparation method, and application

A preparation method for a material for producing macromolecule air fibers, comprising the following steps:

• S1:
• preparation of doped antibacterial far-infrared ceramic powder:
• adding tetrabutyl titanate, zinc acetate, and zirconium acetate to ethanol, adding polyvinyl alcohol and thiocarbamide, stirring and mixing evenly, adding hydrochloric acid dropwise, stirring and reacting, centrifuging, washing, drying, calcining, and ball milling to obtain the doped antibacterial far-infrared ceramic powder;
• S2:
• preparation of magnetic doped antibacterial far-infrared ceramic powder:
• adding the doped antibacterial far-infrared ceramic powder to water, adding ferric chloride and ferrous chloride under inert gas protection, adding ammonia water dropwise, heating, stirring and reacting, centrifuging, washing, drying, and calcining to obtain the magnetic doped antibacterial far-infrared ceramic powder;
• S3:
• preparation of modified ceramic powder:
• adding the magnetic doped antibacterial far-infrared ceramic powder to water, adding tannic acid and catalyst, heating, stirring and reacting, separating by magnet, washing, drying to obtain the modified ceramic powder;
• S4:
• melt spraying:
• adding TPEE to a screw injection molding machine, heating, melting and spraying, and then stretching under an action of hot air, after being pulled by a stretching airflow, blown towards a drum and collected on the drum, and synthesized into TPEE air fiber membrane by its own thermal adhesion;
• S5:
• preparation of the material for producing macromolecule air fibers:
• dissolving water-soluble chitosan in water, adding the modified ceramic powder, stirring and mixing evenly, immersing in the TPEE air fiber membrane, evenly dropping Genipin solution, heating and reacting, removing the membrane, washing, drying, and preparing the membrane as the material for producing macromolecule air fibers.
