Abstract
A wound dressing of alginate staple fibers has improved integrity when its fibers have been hydroentangled. Even when its basis weight is as low as 50 g/m.sup.2, the resulting wound dressing, when saturated with saline fluids, can be removed by forceps from a wound as a single piece, having little or no residue in the wound. At basis weights below 50 g/m.sup.2, the wound dressing preferably includes reinforcing fibers such as rayon.
