Abstract

A polysaccharide fibre useful in biomedical applications such as wound management is made as a bicomponent fibre with alginate and psyllium polymers. An antimicrobial silver salt may be incorporated. The fibre may be made by extruding an aqueous mixture of alkaline solubilised psyllium and sodium alginate into a calcium chloride bath.
