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