The dewelry® super water repellent treatment which is unique to Asakura Senpu Co.,Ltd. makes use of eco-friendly water repellent agents that are PFOA-free (Perfluorooctanoic Acid).
The dewelry® treatment is applied to all “water dancer products” and dewelry® which are characterized by a high level of water repellency and machine washing durability.
Although there are some differences depending on the type of fabric used, our products' water repellency performance does not degrade even after more than 50 washes*.
Although it is more difficult to maintain wash durability by using eco-friendly, PFOA-free materials, we, at Asakura Senpu Co.,Ltd. succeed at maintaining both a high level of water repellency and wash durability thanks to our century-long tradition of knowhow and expertise.
