Abstract: 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.
