                Iida Senko’s unique eco-friendly dyeing
                method
                minimizes environmental impact by thoroughly
                reviewing all dyeing processes,
                from the selection of dyeing machines and
                optimization of dye formulations
                to the choice of chemicals. This method reduces
                water usage and CO2 emissions
                by over 30% compared to traditional methods.

                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.

                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.
