THE SUSTAINABILITY OF THE COTTON CATIONIZATION DURING THE MERCERIZATION PROCESS

<p>Wastewater from the textile industry is a complex mixture of many environmentally harmful substances such as unbound dyes and auxiliaries, pesticides, heavy metals and large quantities of salts associated with the dyes or the dyeing process. To reduce the wastewater load, action can be taken in two directions - firstly, by changing the charge of the cotton fibers to remove salts from the bath and increase the dye yield, and secondly, by producing filters for wastewater treatment. In the interest of sustainability, this article collects the possibilities of using cationized cotton during the mercerization process for this purpose. The results of zeta potential and coloristic parameters confirmed that the cationizated bleached and recycled cotton waste during the mercerization can be used in dyeing and printing without electrolyte, as well as filter for first step in water treatment.</p>
