ABSTRACT:
Textile products comprising a cellulosic substrate are colored with two or more dyes which differ in their respective resistance to chlorine bleaches. The initial color of the textile is determined by the combined effect of the dyes. Thereafter, textile products which may be in the form of garments, bed linens, draperies, or yard goods, are treated with an aqueous solution of bleach to decolorize, to a pre-determined degree, one or more of the dyes, to thereby change the color of the textiles.
