THE INFLUENCE OF THE TEMPERATURE ON THE SORPTION OF MICROEMULSIONATEDCATIONIC SOFTENERS ON COTTON

Cationic softeners are surfactants which, when added to the last rinsi ng during the washing of textile materials, impart a series of desirab le properties, whose intensity depends on the sorption process. This s orption becomes more effective if the product is used in microemulsion form, as its penetration is facilitated in the textile substrate. The sorption kinetics of various cationic softeners (difatty alkylammoniu m and amidoimidozoline compounds) on cotton towel fabric have been stu died as a function of water application temperature. The chemical stru cture of the softener is also considered.
