PURPOSE:To obtain a level dyed material having hue with depth according to one-stage dyeing by bleaching a fiber structure composed of cellulosic fiber and protein fiber, then pretreating the bleached structure with a cellulase enzyme and subsequently coloring the resultant structure with a dye for the cellulosic fiber. CONSTITUTION:A dyed protein fiber-containing cellulosic fiber structure, obtained by bleaching a fiber structure such as yarn or fabric composed of cellulosic fiber and protein fiber with, e.g. hydrogen peroxide, then enzymically treating the resultant structure with a cellulase enzyme, carrying out weight reduction treatment by about 1-3%, subsequently coloring the structure with a dye for the cellulosic fiber, preferably a reactive dye according to one-stage dyeing, excellent in level dyeing properties and having hue with depth. |
