Abstract
Swelling behaviors of Lyocell and Polynosic fibers are investigated by measuring fiber sizes in ferric sodium tartrate complex (FeTNa) and NaOH solution. They showed an anisotropic swelling behavior, i.e., a large expansion in a radius and small shrinking in a longitudinal direction. Birefringent structure was maintained in Lyocell fibers in the swollen state but not in Polynosic fibers for both solvent systems.
