ROLE OF AUXILIARIES IN COTTON ABSORBENCY VARIATIONS

In this study, the effect of various auxiliaries on the variation of water absorbency of cotton depending on the drying temperature and the possibility of providing homogenous and stable absorbency values were investigated as well. Alkaline pectinase scouring, conventional alkaline scouring and bleaching and different drying temperatures were applied and the best absorbency values were obtained under the drying conditions at room temperatures. Absorbency decrease was detected after high temperature dryings in some cases depending on the process conditions, wetting and complexing agent kind. Use of wetting, complexing and washing agents were found to be effective to obtain satisfying, homogenous and consistent absorbency through better cleaning effect in fibers. Nonionic wetting agent, acrylate and polycarboxylic acid based complexing agent ensured the most satisfying results. Washing agent also supported absorbency due to its wetting and emulsifying effect. Better emulsification in a proper way improved the absorbency values and prevented from absorbency decrease through heat treatment.
