Hohenstein Approves Happy Co. Wet-Cleaning System

Experts at Hohenstein Institute, the German-based international research center, have approved Happy Co. Ltd.’s wet-cleaning system after finding it does not alter the size or shape of textiles labeled as dry-clean only.

The system is designed to professionally clean textiles, like outerwear, without using the organic solvents or dry-cleaning processes outlined on their care labels. The usual damage caused by wet-cleaning is dimensional, which often makes the garment unusable. However, when Hohenstein evaluated the effects of Happy Co.’s system on more than 1,000 different garments labeled as “cleanable in organic solvents only,” it did not notice any change.

These methods as well as devices using this “gravity-free balance wet-cleaning system” have obtained several patents in Japan, Europe and other countries. Until now, wet-cleaning technology was only usable for textiles suitable to be washed in water. Most of these textiles are labeled with the “washing tub” care symbol, while the wet cleaning care symbol is used less commonly.

According to Hohenstein, cleaning with water is defined as a cleaning process in the EN ISO 3175-4:2003 standard and is common in several facilities. EN ISO 3758 allows garment manufacturers to label their products with care instructions that include wet cleaning technology.

The research center says the use of water-based cleaning processes in professional textile care helps reduce the use of organic solvents, ultimately reducing the environmental impact caused by the emissions from this process.
