NOVELTY - Preparing photothermal textile comprises (i) placing natural powder in a mixed solution of alcohol organic solvent and water and uniformly stirring, adding photothermal nanomaterials, continuously stirring and uniformly mixing, performing suction filtration, washing and drying to obtain photothermal composite powder, (ii) adding the thickener into deionized water and stirring until dissolved, and adding the binder and continuously uniformly stirring, adding the photothermal composite powder obtained in the step (i), stirring and uniformly mixing to obtain photothermal slurry, (iii) placing the textile to be functional finishing in the photo-heating slurry obtained in the step (ii) for padding treatment, and orderly pre-drying, washing and baking to obtain textile with photoinduced heating function. USE - The method is useful for preparing photothermal textile. ADVANTAGE - The method has short process cycle, low production cost, strong practicability, and good industrial application prospect.
