ABSTRACT:
The flame-resistant properties of aramid fibers are improved using a swelling agent to introduce a flame retardant into the fiber. The treated fiber has properties of strength approximating the untreated fiber, flame resistance greater than the untreated fiber and is conveniently dyed to an unlimited range of colors with high color yield. An aqueous dimethylsulfoxide solution is used as the swelling agent.
