Abstract

The process operates with several chambers one behind another in which laundry is treated in succession in a pre-wash stage (VW), a washing stage (KW), a rinsing stage (SP), a post-treatment stage (NB) and a spin-drying stage (EW), a disinfectant and/or bleaching agent and process water are added viz.: rinsing water (SW) in the washing stage (KW) and pressing water (PW) and post-treatment water (NW) in the rinsing stage (SP) and/or the washing stage (KW). The hygienic and aesthetic demands on the laundry treatment are permanently met if the active oxygen content and the salt concentration of the process water is found and, in at least one of these stages (SP; NB; EW), the active oxygen content of the process water is continuously maintained at between 80 and 120 ppm by suitably metering a disinfectant and/or bleach in aqueous solution and the salt concentration in the process water is kept below 1200 mg/l by the metered addition of fresh water to the last chamber of the rinsing stage (SP) and/or the post-treatment stage (NB), where the quantity of disinfectant and/or bleach and of fresh water added to the quantities of post-treatment water (NW) and pressing water (PW) recirculated into the rinsing stage (SP) is set at a ratio in such a way that the aforementioned composition of the process water is set taking account of the process water additives taken with the laundry to the post-treatment stage (NB).
