Dyes are indispensable elements for providing the apparel industry with colors and levels of brightness.
In order to attain this level of brightness, vast quantities of water have to be used in the dyeing process, and because this involves the subsequent disposal of waste water containing chemical properties, it could potentially cause environmental pollution.
As a part of our environmental activities, YKK has developed ECO-DYE technology that?utilizing supercritical fluid dyeing ("SFD") technology?allows the reduction of the amount of water used in the zipper dyeing process to almost zero.
This technology enables us to manufacture the same high-quality products while reducing the burden on the environment.
