    摘要: Described are methods and systems for cationizing and dyeing a natural fiber-containing textile. The method includes a step of steam treating a textile padded with a base and cationizing agent in a defined temperature range (greater than 100° C. to less than 110° C.) and for a defined time period (1 min to 10 min). The cationizing agent in the presence of the base is capable of generating two epoxide groups. The cationization step in the presence of steam using the halogenated catonization agent of the invention facilitates improved dyeing.
