Washing process for textiles in an automatic washing machine, with application of active washing substances, structural substances and bleaching agents, involving loading of the textiles in the washing machine, adding water, agitating the textiles in the washing solution, pumping off the washing solution, and sequential rinse cycles, wherein the following active substances or combination of active substances are maintained in pumpable form in separate containers and added to the mixture in pumpable form before or during the washing process: 1. Active washing substances, 2. Structural substances, 3. A stabilized bleaching agent, if required, 4. A catalyst which accelerates the bleaching process, if required, and 5. A soft rinse agent, if required. After loading of the textiles to be laundered, the water is added in the ratio of 1:4 to 1:30 of kg. dry textile to liters water, 0.5 to 3.5 g of active washing substances per liter washing mixture are added, 2 to 6.5 g structural substances per liter washing mixture are added, washing carried out at a predetermined temperature with agitation for a period up to 50 minutes, the washing solution drained off and the washed textile subjected to 2- 5 rinse cycles.

Crude 1,10-decanedicarboxylic acid produced by the nitric acid oxidation at 20.degree.14 60.degree. C. of cyclododecanone, cyclododecanol or a mixture thereof can be purified by distillation to a purity suitable for use in the production of polyamides and polyesters by reducing prior to distillation, e.g., by heating to 70.degree.-90.degree. C., the organically bound nitrogen content and as required the nitric acid content, e.g., by washing, and water content thereof so that the sample which is distilled has maximum contents thereof of 0.05%, 0.02% and 0.1% by weight, respectively, and distilling the pre-purified sample at a sump temperature of 215.degree.-225.degree. C. and at a pressure of 0.5 - 2 torr.
