It is possible to dissolve an appropriate amount of an organic solvent and perform washing with an optimum detergent composition. For general products such as coats and suits with a large amount of dirt, the liquid temperature is set to about 30 ° C, and a petroleum solvent is dissolved in HFE and / or HFC by about 40 vol%.
Wash thoroughly. For products such as knits and blouses with a relatively small amount of dirt, the liquid temperature is set to about 5 to 10 ° C., the amount of dissolution of the petroleum solvent is reduced to about 12 to 15 vol%, and mild cleaning is performed. Also, for special print products and animal hair products that are relatively small in the amount of dirt and are susceptible to damage such as change in texture due to dissolution, use HFE or HFC that does not contain petroleum-based solvents, lower the liquid temperature, and wash as weakly as possible. Perform
In addition, special print products and animal hair products that have relatively large amounts of dirt and are susceptible to
Using HFE and / or HFC containing no petroleum-based solvent, the detergency is adjusted by adjusting the temperature, and an oil absorbing agent is used in combination to prevent re-contamination by oily dirt.
