ABSTRACT:
Cellulosic fibers are converted to cellulosate by immersion in an alkali metal hydroxide and then reacted with an aqueous solution of thioarylsulfonium salts to produce modified cellulosic fibers which are substantive to acid, direct, disperse, reactive and sulfur dyes. Cellulosic/synthetic and cellulosic/wool blends can also be treated to produce a fabric blend comprising modified cellulosic components that are substantive to diverse dye classes and synthetic and wool components which are substantive to a single dye class. When using a disperse dyebath of one color the entire fabric blend is dyed one color. When adding an acid, reactive or sulfur dye of a second color to the dyebath, the synthetic or wool component is dyed one color and the cellulosic component is dyed a different color.
