ABSTRACT:
A non-woven alginate fabric useful as a wound dressing is made by spreading a tow of calcium alginate filaments in a flow of water, overfeeding the spread filaments onto a water-pervious support so that the filaments cross over each other and drying the filaments so that the alginate filaments become bonded to each other at their points of contact where they cross over each other. The filaments used have preferably been stretched in an atmosphere of steam and water-washed but not dried and are preferably dried by suction on the water-pervious support.
