It functions in the same way to repel sea water, so it can also be used for sea bathing. However, please make sure to wash it as quickly as possible, otherwise salt residue will remain.

In addition, the polyester material of the fabric does not produce dioxins even if burnt.
You can use the product with confidence.
Q. How durable is the “dewelry®” treatment?
There are slight differences between the types of cloth fabric, but the water repellency after approximately 50 washes will be greater than or equal to Grade 4 (using the JIS L 1092 water repellency test (spray method)).
Q. How should I care the products?
The water repellency is reduced if detergent or oil adheres to the cloth, but returns to normal after being washed.
However, since fabric softener is water-absorbent, its usage should be avoided to prevent reduction of the water repellency.
Similarly, if something with a lot of fabric softener, such as baby detergent, is used, please rinse the cloth well.
Additionally, after filling with water and wringing out a number of times, the water repellency will return to normal after ironing (at a medium temperature, less than 160°C).
Q. If the material is polyester, isn't static electricity generated?
Please note that, although static electricity is less noticeable in summer, static electricity is likely to occur in winter, particularly on dry days.
