Assessment of the possibility of transition to energy-saving mode of cellulosic materials dying process

The most environmentally harmful process in the technology of finishing textile materials is the preparation of cellulosic textile materials using various chemical reagents: alkalis, acids, chlorine - containing oxidants. The use of enzyme preparations in the technology for the preparation of textile materials allows the process to be carried out in more "sparing" conditions from the point of view of environmental safety. Studies have been carried out to assess the possibility of using enzyme technologies to replace alkaline decoction in technologies for preparing cellulose textile materials for dyeing with active dyes. The selectivity of the dye from the dye bath, the degree of fixation of the dye and the quantitative content of the dye on the cellulose fiber were studied. The color sponging program has proven to increase the brightness and color uniformity of finished canvases that have undergone preliminary enzymatic pretreatment. The possibility of switching to an energy - saving, more environmentally friendly mode of dyeing cellulose materials with active dyes at a temperature of 60 °C by replacing the alkaline decoction operation with biopreparation of cloths has been proved.
