There is disclosed a process for printing fibre material by the direct printing process, which process comprises printing the fibre material with a print paste comprising at least one dye, one cellulose derivative or alginate as thickener as well as further customary assistants and wherein the print paste comprises .ltoreq.5% by weight, based on the print paste, of a homopolymer or copolymer based on acrylamide. The novel process makes it possible to obtain strong patterned prints on a white ground which have good levelness, good fastness properties and sharp contours. The print pastes are distinguished by good homogeneity, good storage stability and simple handling.

Process for printing fibre material by the direct printing process

A process for dyeing or printing cellulosic fibre material with reactive dyes, which comprises dyeing or printing said material with at least one reactive dye that contains a chlorotriazinyl radical, and washing off the dyeing or print so obtained with an aqueous solution to which at least 0.01 gram per liter of an alkaline earth metal salt has been added. Dyeings and prints of good fastness properties are obtained.
