Abstract (en)

[origin: US2014304925A1] Washed laundry that has been rinsed still contains bound acidic or basic rinsing liquid. In many cases this must be neutralized. This used to be conducted on the basis of values gained from experience, which generally resulted in only partial neutralization. Herein, sample liquid is taken continuously from the neutralization chamber (18) and, after the fine filtration of same, the pH value of the sample liquid is continuously measured by a pH value measurement device (31). In this manner a pH value control system is possible which ensures an automatic and complete neutralization of the rinse liquid still bound in the laundry after rinsing.
