Abstract

A submicron-sized fiber has a polycarbonate shell and a polyurethane core, and is made by electrospinning liquid solutions of the materials through co-axial capillaries. The composite fiber may be laid onto a collector to form a nonwoven membrane, or may be laid or adhered onto a fabric substrate. A nonwoven membrane or fabric with the composite fiber combines the filtration efficiency of the polycarbonate with the mechanical characteristics, such as elasticity, of polyurethane. The membrane or fabric is useful in exposure suits, filters and aviation dresses/clothing.
