Therefore, there are many problems in laundering. Hakuyosha has established the crystal laundering method for delicate materials and increased customer satisfaction.

He says people in laundering businesses need to achieve the following for their survival:

•What laundries are required to do is making a choice between competition for convenience and competition for professionalism.

•What laundries need to do as a pro is to provide customers with good qualities (laundering, stain removal and finishing) in reasonable prices in order to fit in with customers' needs.

•Definition of laundering is removing stains from substrates using physics and chemistry and restoring an original form in finishing.

•Disadvantages of washing with water are swelling, relaxation, milling, fibrillation and dryness.

•Disadvantages of dry cleaning are insufficient removal of water soluble stains, excessive solubility, reverse staining and unfriendliness to the environment.

•Types of staining and laundering methods:Water soluble staining, oil staining and insoluble staining

•Difference in staining due to gaps in clothing:On garments there are a lot of insoluble stains that require the use of machines.

•Laundering methods required in the future:Laundering cannot be done professionally even though dry cleaning or rinsing is carried out.

•New rinsing-crystal laundering:Laundering methods requiring various degrees of mechanical power according to the types of staining and materials

•New laundering method:The solubility of dry cleaning is usually too high, however, the new dry cleaning method has appropriate solubility and does not affect the environment.
