Abstract
The purpose of this research was to establish the link between the surface of pristine polyester knitted fabrics before and after alkali hydrolysis modification, as well as the composition of effluents following standard and innovative washing processes. Using the streaming potential method, substantial variations in the surface of the pristine knitted fabrics after ten washes in the standard and innovative washing processes were discovered in comparison to the alkalihydrolysed knitted fabrics. The results of the tests carried out with the selected processes establish a relation between the properties of pristine and the alkaline hydrolysed knitted fabrics and the composition of the effluents and filter cakes. The results revealed that the innovative washing process has the potential for further investigations into the release of microfibers from knitted polyester fabrics.
