NOVELTY - Method of preparing far-infrared thermal insulation functional cotton fabric involves mixing far-infrared ceramic powder, fixing agent polyurethane, JFC penetrating agent, and deionized water uniformly to obtain mixed solution, adding graphene oxide and polytantalate to the mixed solution, performing ultrasonic treatment, dispersing uniformly, and adjusting the pH to 5-6 to obtain far-infrared thermal insulation finishing solution, soaking cleaned and dried cotton fabric in far-infrared thermal insulation finishing solution for 1-2 hours, padding, drying, and baking in sequence to obtain graphene oxide far-infrared thermal insulation cotton fabric, immersing graphene oxide far-infrared thermal insulation cotton fabric in hydrosulfite solution, performing reduction reaction, removing, washing, and drying. USE - Method of preparing far-infrared thermal insulation functional cotton fabric (claimed). ADVANTAGE - The method provides cotton fabric having lightweight, softness, exquisite hand feeling, and good heat preservation effect.
