Why does the color fade mostly on the initial wash, and then minimally thereafter?
During the manufacturing process, much of the excess pigment imbedded into the fabric fibers is washed out. However, some excess remains and is removed the first time you wash the item. This results in a slightly faded item that is actually more effective in transmitting the desired light than when the item was unwashed and over populated with fluorescent pigment. Too much pigment lessens the transmission, so the first wash brings the garment to the perfect transmission of therapeutic light.
