After 10 Washes





This antibacterial, antiviral, and deodorizing
fiber retains its antiviral effectiveness even
after 10 washes,
addressing the previously difficult challenge of
achieving this with polyester fabrics.
Antibacterial
Properties
for washing





Using a patented technique (Patent No.
5031917),
components adhered to the surface of nylon
fibers absorb surrounding heat upon contact
with moisture from sweat or breath,
thereby activating a cooling effect.
This treatment offers excellent moisture
absorption and quick-drying properties,
reducing stickiness and discomfort during wear,
and providing superior wash durability.
