    摘要: Processes for producing multicolor crossdyed cellulosic fabrics which are fully or partly crosslinked are disclosed. These processes include: (1) crosslinking preselected areas of fabric with a grafted cationic group and leaving other areas untreated; immersing the fabric in an acidic anionic dyebath to dye the cationic areas and then immersing in a different colored, alkaline, unreactive dyestuff dyebath to dye the untreated areas and produce a bicolored fabric, (2) crosslinking fabric areas with a grafter cationic group and then the remaining areas with an anionic group; immersing in an acidic, anionic dyebath to dye the cationic areas and the immersing in a different colored cationic dyebath to dye the anionic areas and produce bicolored fabric, and (3) preselecting and treating areas of fabric to be cationic, anionic and untreated; immersion dyeing as above the cationic, untreated and then the anionic areas of fabric to produce a multicolored fabric.
