Rational modes of wool scouring

Abstract

Introduction. Currently, synthetic detergents with a weakly alkaline pH are used for scouring wool. The combination of surfactant Sles 70 with an aprotic organic solvent with dimethylsulfoxide (DMSO) allows you to create a neutral detergent and needs to determine the rational modes of wool scouring. The purpose of our study was to find the rational parameters of scouring fine-wool hair. Materials and methods. In Latin squares, an experiment was conducted to determine the effect of the concentration of Sles 70 in the scouring solution in the range of 0.1 to 3.1 g/dm 3 , the concentration of DMSO 0.01 to 0.61 g/dm 3 , the hydromodule 10 to 100, the temperature of 30 − 48  С for cleaning fine-wool fibers while scouring the wool fiber with the specified combined detergent. Results and discussion . In the investigated range of variation of factors, the influence of the hydromodule on the purification of wool and the extraction of extractive substances from the surface of the fiber into the waste solution was most pronounced. Hydro module more you the wool grease and dirt. The temperature has a stable effect in the given range, so all the investigated values temperature to the removal of fatty contaminations of wool for this component of the detergent solution.
