ABSTRACT:
Continuous dyeing of poly(m-phenyleneisophthalamide) fibers using a swelling agent to introduce a dye into the fiber. The dyed fiber has properties of strength and fire retardance approximating the original undyed fiber and is conveniently dyed to an unlimited range of colors with high color yield and relatively good lightfastness at a resonable cost. An aqueous dimethylsulfoxide solution is used as the swelling agent.
