Textile printing

The textile printing process involves local dyeing to obtain a predetermined pattern. All types of fibers require proper preparation before printing. A previously prepared paste, which contains dyes or pigments, is applied to the textile substrate. Then, the already prepared fibers are subjected to a printing process, which can be performed by various methods (e.g. flat, rotational and spray film printing). After the process is completed, fixation takes place, otherwise called drying. The final stage is washing, thanks to which, non-fixed dye particles and various chemicals used to prepare the printing paste (such as dispersants or emulsifiers) are removed from the fibers. Ethoxylated nonylphenols, i.e. ROKAfenol products, work perfectly in this application. Their detergent, emulsifying and cleaning properties make them effective in supporting washing processes. ROKAfenol products can be used to clean different fibers, both wool and cotton, as well as chemical fibers, bristles and leather. Their resistance to high temperature and high concentration of electrolytes ensure the use in difficult conditions in the textile industry, for example in the process of washing wool and boiling cotton.
