Studies on the Foam Washing of Wool

양모의 포말세정에 관한 연구

This paper has been studied on the method of washing without any damage on wool, namely foam washing method. Effect of washing was obtained with experimental equipment manufactured by way of trial. but some deflects were found that the volume of detergent solution and blow ratio changed with time passes by. This difficulties should be improved by farther studies. The solution mixed with sodium oleate ($0.5\%$) and sodium carbonate ($0.3\%$) was found suitable for detergent solution, and under the conditions of washing temperature at $50\~60^{\circ}C$ and washing time for 5 minutes, the washing effect was obtained good. Desoaping treatment with $Na_2CO_3$ solution after washing might be thought to be necessary, and from the scanning electron micrographs (SEM), no damage on wool and wool sureface washed was, observed. From the results of this study foam washing of wool may be expected to be very effective.
