ABSTRACT:
Cellulose fiber materials are dyed with a dye represented by a free acid of the formula, ##STR1## wherein W.sub.1 and W.sub.2 are independently a direct linkage or a bridging group, Q.sub.1 and Q.sub.2 are independently a fiber-reactive group, A.sub.1 and A.sub.2 are independently a phenylene or naphthylene group unsubstituted or substituted, D is a residue of 1-amino-8-naphthol mono- or di-sulfonic acid, m and n are independently 0, 1 or 2, provided that they satisfy the formula, 0<m+n.ltoreq.2, and each sulfo group appended to A.sub.1 and A.sub.2 is located at the carbon atom adjacent to the azo group, and then finished with a finishing agent capable of bonding with cellulose through a bridge formation, thereby obtaining dyed and finished products excellent in anticrease and shrinkproofing properties as well as various fastness properties such as light fastness, perspiration light fastness and chlorine fastness without any color change.
