The dyeabilities of wool with reactive scarlet X-3B and reactive black KN-B hydrolyzed under certain conditions were investigated in this paper. Via orthogonal tests, the optimized process with hydrolyzed reactive dyes was obtained. The results proved that wool dyeing with the hydrolyzed dyes under acidic conditions could get higher exhaustion and depth, color fastness to rubbing and soaping are superior to acid dyes with similar chemical structures.
