Apparatus for improving mechanical characteristics of nonwoven materials
First Claim
1. An apparatus for forming a nonwoven material from a liquefied polymer, the apparatus comprising:
- (a) a precipitation electrode;
(b) a dispenser spaced apart from said precipitation electrode, and defining a first axis therebetween, said dispenser being at a first potential relative to said precipitation electrode; and
(c) at least one rotating electrode being laterally displaced from said dispenser, being at a second potential relative to said precipitation electrode and operable to rotate around said first axis;
said dispenser and said at least one rotating electrode being designed and constructed such that the liquefied polymer is dispensed from said dispenser and forms a plurality of entangled fibers moving in a direction of said precipitation electrode, hence forming the nonwoven material thereupon.

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.
