  4. Printing with Pigments After applying the printing paste, the fabric is dried and then the pigment is normally fixed with hot air (depending on the type of binder in the formulation, fixation can also be achieved by storage at 20 °C for a few days). The advantage of pigment printing is that the process can be done without subsequent washing (which, in turn, is needed for most of the other printing techniques).

  5. Dye Printing • The process traditionally starts with the preparation of the paste. Compared to pigment printing, the composition of the pastes is more complex and variable, being determined not by the dye used, but by the printing technique, the substrate, the application and the fixation methods applied. • Apart from the dye, printing pastes contain a thickening agent (see also Section 8.7.1) and various other auxiliaries, which can be classified according to their function as follows: • · oxidising agents (e.g. m-nitrobenzenesulphonate, sodium chlorate, hydrogen peroxide) • · reducing agents (e.g. sodium dithionite, formaldehyde sulphoxylates, thiourea dioxide, tin(II) chloride) • · discharging agents for discharge printing (e.g. anthraquinone) • · substances with a hydrotropic effect, like urea • · dye solubilisers, which are polar organic solvents like glycerine, ethylen glycol, butyl glycol, thiodiglycol, etc. • · resists for reactive resist printing (e.g. sulphonated alkanes) • · defoamers, (e.g. silicon compounds, organic and inorganic esters, aliphatic esters, etc.). • All the necessary ingredients are metered (dosed) and mixed together in a mixing station. Since between 5 and 10 different printing pastes are usually necessary to print a single pattern (in some cases up to 20 different pastes are applied), in order to reduce losses, due to incorrect measurement, the preparation of the pastes is done in automatic stations. In modern plants, with the help of special devices, the exact amount of printing paste required is determined and prepared in continuous mode for each printing position, thus reducing leftovers at the end of the run. • It is common practice in many printing houses to filter the printing pastes before application, using for example a filter cloth. This operation is especially important for thickeners to prevent free particles from blocking the openings of the screens.
