ABSTRACT:
A solution of elastomeric polyurethane in a volatile solvent is centrifugally sprayed onto a base in a strong electrostatic field to form long fibers that are swept across the base and deposited thereon in generally straight condition, overlapping and adhered to previously deposited fibers. Novel fibrous sheets of high strength are thus produced. The intersecting fibers may be ribbon-like.
