Abstract
The invention provides a method for preparing down feather with a self-cleaning function. The method comprises the following steps: (1) constructing a light degradation system by using sulfonated polyetheretherketone and polypeptide; (2) soaking and dehydrating; and (3) spraying a water-repellant and oil-repellant finishing agent to prepare the down feather with the self-cleaning function. The surface of the prepared down feather is coated with a layer of sulfonated polyetheretherketone/polypeptide powder film and water-repellant and oil-repellant components. The water-repellant and oil-repellant components are used for preventing most pollutants from staining the down feather. Even if the down feather is stained by pollutants, the sulfonated polyetheretherketone/polypeptide powder film can form active free radicals under the irradiation of ultraviolet light, organic pollutants on the down feather are degraded by using the photocatalytic performance of the active free radicals, and pollutants is eliminated, so that the self-cleaning function is realized. The down feather with the self-cleaning function prepared by using the method is not wetted when being soaked into tap water for 72 hours, and is not wetted when being soaking into salad oil for 48 hours; the degradation rate of the simulated pollutant of methyl orange is over 60 percent, and the light degradation effect is not lowered after five times of water washing.
