ABSTRACT:
Described is a process for the printing and pad-dyeing of mixed fabric made from fiber mixtures consisting of material consisting of materials dyeable with disperse dyestuffs and materials dyeable with reactive dyestuffs, especially polyesters/cotton, by the use of printing pastes or padding liquors containing at least one disperse dyestuff of the azo series and at least one reactive dyestuff, wherein there is used a printing paste or padding liquor in which the disperse dyestuff is formed in the printing paste or padding liquor. There are obtained by this process printing or dyeings which have some advantages over the prior art. The staining of the cellulose constituent can more easily be washed out and only a slight staining of white ground occurs.
