Abstract: 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.

Abstract: The present invention provides strategies to improve the moisture management properties of textiles while retaining high comfort levels. The treatments also help to protect textiles against microbial growth. The treatment strategies of the present invention are based at least in part on the use of cationic bis-imidazoline(s) and their salts. Quaternized bis-imidazoline cations and their salts are particularly preferred.

Abstract: The current invention provides methods provides a novel process to dye polyester/natural fiber blends in an all in one step dyeing process. This all in one step dyeing process is enabled by pre-treatment of the fabric using one or more synthetic cationizing agents. The all in one dyeing is then able to be carried out at a lower temperature and a neutral pH, using a combination of disperse and reactive dyes.
