The invention discloses a preparation method of an antibacterial and heat-insulating cloth functional layer, which is characterized by comprising the following steps: mixing double-ended epoxy silicone oil, 1,3-dihydroxyethyl-5,5-dimethyl hydantoin , the basic catalyst is added to the organic solvent, and the reaction is stirred at 90-100 ° C for 6-8 hours, after filtering, rotary evaporation to remove the solvent, after dissolving with isopropanol, spraying, and ventilating and drying. The functional layer of the antibacterial heat-insulating fabric disclosed by the invention has good film-forming property, wherein the silicone oil segment plays a hydrophobic role, prevents rainwater or other aqueous solutions from infiltrating and is directly blocked on the outside, and at the same time has a heat insulating effect, and the hydantoin segment has a hydrophobic effect. It can give good antibacterial effect to the fabric. |
