Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
We claim: 1. A process for cleaning fibers, the process comprising: generating free OH radicals and/or H 2 O 2 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 H 2 O 2 ; 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 cm 2 . 2. The process according to claim 1 , wherein the aqueous solution further comprises at least one compound selected from the group consisting of a builder and an enzyme. 3. The process according to claim 1 , wherein the process is carried out at a temperature of up to 60° C. 4. The process according to claim 1 , having an at least 20% degree of soil removal for bleachable stains. 5. The process according to claim 1 , wherein the diamond electrode is a boron-doped diamond electrode.
