Removal of dye from originally dyed textile garments and their transfer and disposal to other uncoloured (white and light coloured) garments present in the same wash bath during washing is known as “dye re-deposition” and is one of the most common problems encountered when washing clothes. Another problem with laundry is the removal of microbiological contaminants, which is becoming critical with the increasingly used low washing temperatures and the use of detergents without aggressive bleaches, due to the pursuit of energy-efficient household appliances and environmental awareness. In doing so, household washing procedures are less defined in terms of microbiological efficiency and are still not conducted as they should be, although they are becoming increasingly important. Microbiological efficiency is also a major cause of unpleasant laundry odor.
