A process is described for the application of dust-laying oil to woollen blankets, in which use is made of a positively charged oil-in-water emulsion. During a commercial-scale trial of this process, difficulty was encountered in the form of a progressive build-up of oil and fatty acid after repeated laundering and oiling. The inclusion in the laundering formula of modified soda in a soap: soda ratio of 3:1 has been found to give satisfactory control of the fatty acid content, and to assist greatly in preventing the accumulation of oil. |
