Abstract
Superabsorbent synthetic fibers are prepared by a method wherein segments of synthetic fibers are coated with a solution of (a) a hydrophilic, uncomplexed polymer and (b) a complexing agent, and the coated fibers are fluff or flash dried causing the polymer to complex and to form a superabsorbent coating on the synthetic fibers in situ.
