Abstract
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.
Claims9
A process for printing fibre material by the direct printing process, which process comprises applying to the fibre material a print paste comprising at least one dye, 10 to 100 g of an alginate per kg of print paste as thickener as well as further customary assistants, and subsequently fixing the dye, and wherein the print paste comprises .ltoreq.1% by weight, based on the print paste, of an acrylamide homopolymer having an average weight of 0.5 to 1 million of a copolymer of acrylamide and acrylic acid having an average molecular weight of 1 to 10 million.
