Abstract
When nylon fibers are dyed with a first anionic dye and then treated with a stainblocker, they can be woven into a fabric with untreated nylon fibers and then subjected to a second dyeing process using a second anionic dye of a different color than the color of the first anionic dye, without risk of dye bleed or dye blending during the second dyeing operation.
