Hohenstein Institute approves new Japanese “gravity-free balance wet cleaning system”


Hohenstein has approved a new and innovative wet cleaning system that professionally cleans “dry clean only” textiles in water, developed by Japanese company Happy Co. Ltd. in Kyoto.
The new “gravity-free balance wet cleaning system” is a wet cleaning system for outerwear that cleans customers’ textiles professionally without having to process them conventionally, using organic solvents. The method, as well as devices of the new system, have obtained several patents not only in Japan but also in European and other countries.

Hohenstein has tested the system by evaluating more than 1,000 different garments in a wide range of material composition labeled as “cleanable in organic solvents only”. The results did not show any undue deviation of the original dimensions as documented upon receipts of the garments before they were returned to the customer. The requested dimensional stability of the newly developed wet cleaning system was thus successfully approved by the Hohenstein experts.

Until now, wet cleaning technology was only usable for textiles suitable to be washed in water. This new cleaning system aims to allow wet cleaning of outerwear that according to its care label should only be dry-cleaned using organic solvents, without any negative effects or even damage to the garment. The main usual negative effects or damage caused by wet cleaning processes are dimensional changes of textiles, changes which often make further use of the garment impossible for the owner.

The use of water-based cleaning processes in professional textile care helps to decrease the use of organic solvents and thus reduces the environmental impact caused by the emissions associated with the process.
