Abstract
A fiber is formed by providing a stream of a solidifiable fluid, injecting the stream with a net charge so as to disrupt the stream and allowing the stream to solidify to form fibers.
Claims31
A method of producing fibers, comprising:
- a) providing a stream of a solidifiable fluid;
- b) providing the stream with a net charge so as to disrupt the stream by passing the stream through a body defining an orifice so that the stream passes through an electric field before exiting the orifice;
- and
- c) allowing the disrupted stream to solidify to form fibers.

A method of producing fibers, comprising:
- a) providing a plurality of streams of solidifiable fluid;
- b) providing the plurality of streams with a net charge so as to disrupt the streams by passing each stream through a structure defining an orifice so that the stream passes through an electric field prior to exiting the orifice;
- and
- c) allowing each disrupted stream to solidify to form fibers.

A method of forming a charged solid, comprising:
- a) providing a stream of a solidifiable fluid;
- b) providing the stream with a net charge by passing the stream through a body defining an orifice so that the stream passes through an electric field prior to exiting the orifice;
- c) allowing the stream of solidifiable fluid to solidify while still charged.
A method of forming fibers comprising the steps of:
- (a) providing a stream of a solidifiable fluid at a rate of at least about 0.01 grams per second;
- (b) injecting electrical charge into the stream of solidifiable fluid, whereby the stream will tend to disperse and form filaments;
- and
- (c) solidifying the filaments.
1 more element
A method of forming fibers comprising the steps of:
- (a) providing a stream of a solidifiable fluid at a rate of at least about 0.01 grams per second;
- (b) injecting at least about 0.6 coulomb of electrical charge per cubic meter of fluid into said stream of solidifiable fluid, whereby the stream will tend to disperse and form filaments;
- and
- (c) solidifying the filaments.
1 more element
A method of forming fibers comprising the steps of
- a) providing a stream of a solidifiable fluid at a rate of at least about 0.03 millimeters per second;
- b) injecting electrical charge into said stream of solidifiable fluid, whereby the stream will tend to disperse and form filaments;
- and
- c) solidifying the filaments.
