    • 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.
    • 纤维素纤维通过浸入碱金属氢氧化物中而转化成纤维素,然后与硫代芳基锍盐的水溶液反应,生产对酸,直接,分散,反应性和硫化染料具有实质性的改性纤维素纤维。 纤维素/合成纤维素/羊毛混合物也可以被处理以产生包含改性纤维素组分的织物共混物,其对于各种染料类别是实质性的,对于单一染料类是实质的。 当使用一种颜色的分散染浴时,整个织物混合物染成一种颜色。 当向染浴中加入第二种颜色的酸,反应性或硫化染料时,将合成或羊毛组分染成一种颜色,并将纤维素组分染色成不同的颜色。
