<p>Process for pad dyeing cellulosic textile materials of the disclosure Cellulosic textile material is dyed with substantive dyes or preferably with reactive dyes. Dyeing is carried out by applying to the cellulosic material an aqueous dye liquor which contains, in addition to the dye, a graft polymer which is obtained from an adduct of an alkylene oxide, preferably propylene oxide, with an at least trihydric aliphatic alcohol, e.g. glycerol, and acrylamide or methacrylamide. The cellulosic material is then subjected to a heat treatment, e.g. by steaming or with microwaves, or is stored cold, to fix the dyes. This dye liquor increases the liquor pick-up and thus also increases the dye yield, while at the same time excellent levelness is achieved.</p> |
