Due to pollution and environmental damage countermeasures in recent years, conversion from dry cleaning with a solvent has become an urgent task, which has become a major issue in the cleaning industry. However, the wool-based laundry has a problem that it shrinks and loses its shape when washed with water by a conventional industrial cleaning device. To avoid this, the only effective method is hand washing, which is extremely inefficient. Therefore, as the industrial cleaning, dry cleaning with a solvent is still performed.

Further, as is well known, the washing is dehydrated by a dehydrator and then dried by a dryer after the main washing with a solvent, detergent or water is completed. In the main washing, a large number of laundry items are generally washed in a washing machine at a time, and then dehydrated in the same washing machine.
