ABSTRACT:
The cold water bleed propensity of acid and premetallized acid dyed cationic dyeable nylon fibers is substantially reduced by treating the fibers with both a nylon fixing agent and a cotton fixing agent. Colorfastness of acid and premetallized acid dyed nylon fibers, other than CD nylon fibers, is also enhanced by treating the fibers with both a cotton fixing agent and a nylon fixing agent.
