Topic 1. Minimization in consumption of water and/or chemicals in continuous processes in general Case illustration: Water for rinsing of printing belt Concept In many continuous processes, water and chemicals are dosed independent of the running of fabric. In many cases this means that water or chemicals dosage will continue when the fabric is stopped for whatever reason. This project should assess whether a start/stop of water or chemicals dosage can be automatically connected to the start/stop of the continuous machine and how such an implementation influences the running of the machine and the quality of the fabric. A Danish survey has identified examples of continuous processes in which the mentioned implementation seems possible: water cleaning of the printing belt in printing machines, water cooling of the rubber belt in shrinking machines, water dosage for wetting purposes before drying, water dosage for flushing purposes, etc. Improvement potentials Reduction of consumption of water and chemicals. Relevance A large number of continuous processes. 19
