Abstract
The present invention relates to a washing machine comprising an electrochemical cell, to a process for electrochemical cleaning of fibers, to laundry detergents for electrochemical cleaning of fibers and to the fibers thus cleaned.
Claims5
A process for cleaning fibers, the process comprising:
- generating free OH radicals and/or H2O2 in aqueous solution comprising a surfactant by applying a current strength in the range from 0.02 to 30 A to an electrode, to form a washing solution containing the surfactant and free OH radicals and/or H2O2;
- and
- contacting the washing solution with fibers, thereby cleaning the fibers,
- wherein the electrode is a diamond electrode having an effective surface area in the range from 0.5 to 1000 cm2.
