Method for preparing water-repellent textile

The invention provides a method for preparing a water-repellent textile. An electron radiation technology is adopted, a reactive organic silicon compound is taken as a water repellent, and the textile is subjected to water-repellent treatment. According to the main technical scheme, the method comprises the following steps: padding the textile in a water-repellent or a coating water repellent, radiating, drying or baking, performing after-treatment, thereby obtaining the water-repellent textile. The water-repellent textile prepared by the method disclosed by the invention is excellent in water-repellent performance and can be reacted at normal temperature, the grafting ratio is greatly improved, and the method has the advantages of simple processing technology, simplicity in control and low energy consumption and is worthy of popularization and application.
