Patent ID: 8721319

Claim:
An apparatus for creating superfine fibers, comprising: a spinneret comrising: a body, wherein at least a portion of the body receives material to be formed into a fiber; one or more needles removably coupled to the body; a driver, wherein the spinneret is couplable to the driver, and wherein the driver is capable of rotating the spinneret; and a superfine fiber collection device at least partially surrounding the spinneret, wherein the collection device does not include a device capable of generating an electric field, proximate to the spinneret, that is sufficient to draw a fiber from the needles of the spinneret; wherein the driver rotates the spinneret at a speed sufficient to causes at least a portion of the material disposed in the body or one or more of the needles to be ejected through one or more of the needles and form superfine fibers as the ejected material solidifies.
