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.
Claims15
A washing machine comprising an electrode and a closed-loop control unit, wherein a current strength in the range from 0.02 to 30 A can be applied to the electrode during the washing operation.
The washing machine according to any preceding claim wherein the electrode has an effective surface area in the range from 0.5 to 1000 cm2.
A process for cleaning fibers, which comprises generating free OH radicals and/or H2O2 in aqueous solution by applying a current strength in the range from 0.02 to 30 A to an electrode.
A laundry detergent comprising bleach activator(s) and/or bleach catalyst(s) and less than 1% by mass of hydrogen peroxide or of hydrogen peroxide releaser compounds.
A laundry detergent, selected from the group consisting of fully built laundry detergent, liquid laundry detergent, color detergent and wool detergent.
A kit of parts, comprising a washing machine and an electrolytic cell connectable upstream of the water inlet.
An e-bleach ball comprising a power supply independent of the electricity grid, a diamond anode and a cathode, which are arranged such that the electrodes are able to come into contact with the electrolyte when the e-bleach ball is in the washing drum of a washing machine during the washing operation.
