AI Technical Summary

Benefits of technology

The patent describes a system for producing fibers, such as microfibers and nanofibers, using a fiber producing device that is coupled to a driver. The device includes a body with a cavity for receiving material to be produced into fibers and a coupling member for attaching the device to the driver. The device also includes at least two blades that extend from the body and have a cavity for receiving material. The device can be enclosed in a chamber and the environment inside the chamber can be controlled. The technical effects of this system include the ability to produce fibers with a controlled diameter and the ability to collect fibers on a collection system.

Problems solved by technology

Electrospinning requires the use of high voltage to draw out the fibers and is limited to materials that can obtain an electrical charge.
The high rotational speed used to form the fibers creates high energy requirements, due to rotational air resistance at high speeds.
Additionally, spinnerets generally produce fibers in a single plane, which causes fiber entanglement.

Embodiment Construction

[0025]It is to be understood the present invention is not limited to particular devices or methods, which may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting. As used in this specification and the appended claims, the singular forms “a”, “an”, and “the” include singular and plural referents unless the content clearly dictates otherwise. Furthermore, the word “may” is used throughout this application in a permissive sense (i.e., having the potential to, being able to), not in a mandatory sense (i.e., must). The term “include,” and derivations thereof, mean “including, but not limited to.” The term “coupled” means directly or indirectly connected.

[0026]The terms “comprise” (and any form of comprise, such as “comprises” and “comprising”), “have” (and any form of have, such as “has” and “having”), “include” (and any form of include, such as “includes” and “incl...

Abstract

Described herein are apparatuses and methods of creating fibers, such as microfibers and nanofibers. The methods discussed herein employ centrifugal forces to transform material into fibers. Apparatuses that may be used to create fibers are also described.

Description

PRIORITY CLAIM[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 620,298 filed on Apr. 4, 2012.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention generally relates to the field of fiber production. More specifically, the invention relates to production of fibers of micron, sub-micron and nano size diameters using centrifugal forces.[0004]2. Description of the Relevant Art[0005]Fibers having small diameters (e.g., micrometer (“micron”) to nanometer (“nano”)) are useful in a variety of fields from the clothing industry to military applications. For example, in the biomedical field, there is a strong interest in developing structures based on nanofibers that provide scaffolding for tissue growth to effectively support living cells. In the textile field, there is a strong interest in nanofibers because the nanofibers have a high surface area per unit mass that provide light, but highly wear resistant, garments. As a class,...
