NA.DE. is a depigmentation system consisting of the extraction of natural dark pigment from natural fibers.
DHZERO, instead, is a treatment for the elimination of dark hair which is naturally found in light colored fibers.
Both treatments can be executed on any kind of fiber, but are particularly recommended for luxury fibers (such as cashmere, alpaca and camel hair) which, if not appropriately cleaned with special techniques, are quite difficult (if not impossible!) to dye in pastel colors and pure white. Thanks to studies and research carried out over the past 30 years, both processes have been further improved to ensure that the fiber and its natural tactile characteristics are maintained.
