Apparatus for improving mechanical characteristics of nonwoven materials

Abstract

An apparatus for forming a nonwoven material from a liquefied polymer, the apparatus comprising: (a) a precipitation electrode; (b) a dispenser spaced apart from the precipitation electrode, and defining a first axis therebetween, the dispenser being at a first potential relative to the precipitation electrode; and (c) a system of electrodes being laterally displaced from the dispenser, being at a second potential relative to the precipitation electrode and capable of providing an electric field having at least one rotating component about the first axis; the dispenser and the system of electrodes being designed and constructed such that the liquefied polymer is dispensed from the dispenser and forms a plurality of entangled fibers moving in a direction of the precipitation electrode, hence forming the nonwoven material thereupon.
