METHOD FOR THE WET-TREATMENT, PREFERABLY THE WASHING, OF LAUNDRY

摘要

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.

主权项

1. A method for the wet-treatment, preferably the washing, of laundry, wherein the laundry is first washed and rinsed and, after rinsing, a neutralization of the laundry is carried out in that neutralizing agent is added as necessary to the liquid in which the laundry is located and/or which is bound in the laundry, wherein at least one sample is taken from the liquid, the sample is filtered and at least one pH value of the filtered sample is measured, with neutralizing agent being added as necessary to the liquid in a targeted manner based on the pH value of the liquid obtained from the measurement.
