ABSTRACT:
Polysaccharide fibers are produced by hot extrusion of a gelling polysaccharide into air or a gelling salt bath. Optionally, other polysaccharides, including non-gelling types, may be co-extruded with the gelling polysaccharide. The fibers are useful for the production of wound dressings and catamenial devices, and many other devices.
