Abstract
Abstract Disclosed herein is a process for coloring textile materials to produce random dyed effects wherein a coloring material is added to a foamed composition either before or after the foamed composition is coated onto a textile. The foam is then collapsed to penetrate the coloring material into the textile, and, finally, the textile is dried and cured or fixed.
