Definitions
- the present invention relates to a method for shortening the drying time of machine-washed textiles.
- the EU Regulation on Energy Labeling for Domestic Washing Machines specifies classes for the centrifugal efficiency, ie the residual moisture remaining in the laundry (efficiency classes A to G). Laundry that contains less residual moisture dries faster and consumes less energy when drying in an electric clothes dryer, making the use of tumble dryers more attractive.
- the last spin in a washing machine is used to finalize the drying of the laundry to prepare for drying, either on a leash or in a tumble dryer. For this purpose, the laundry is centrifugally dewatered at spin speeds of 600 to 1600 revolutions per minute.
- the invention relates to the use of carboxylic acids in the rinsing step of mechanical washing processes to shorten the drying time of the washed and optionally spun textiles.
- the shortening of the drying time is achieved by reducing the residual moisture content of the washed textiles.
