A textile dyeing process is described for dyeing a textile material, product or article consisting of animal fibers, comprising the steps of dipping said textile material, product or article into a dyeing bath comprising at least one detergent substance, a wetting substance, a leveling substance and an acidity regulator; adding to the dyeing bath a coloring substance approved for food use; subjecting the dyed textile material, product or article to washes; and finally subjecting the dyed textile material, product or article to a color fixing treatment.

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.

Described are methods and systems for cationizing and dyeing a natural fiber-containing textile, which uses a mono- or di-quaternized cationizing agent. The method includes a step of heating the textile to a temperature in the range of 90° C. to less than 110° C. for a period of time in the range of 1 min to 10 min to react the cationizing agent with the textile. The cationization step in the presence of heat using the halogenated cationization agent of the invention facilitates improved dyeing.

A phase-transfer catalytic color fixation processing method for textile includes the following steps: (1) dry-dyeing a textile with disperse reactive dyes in supercritical carbon dioxide fluid under waterless condition; (2) putting the textile in a phase-transfer catalytic fixation device, taking phase-transfer catalyst as the carrier of circulated supercritical carbon dioxide fluid, transporting the ionized fixing catalytic alkaline substance from aqueous phase to hydrophobic supercritical carbon dioxide fluid phase, getting full contact with functional groups on fibers, resulting in the fixing catalytic reaction with disperse reactive dyes.
