METHODS OF MAKING NANOFIBER YARNS AND THREADS

摘要

There is disclosed a method of making a material comprising an assembly of at least one spun yarn, comprising: synthetic inorganic fibers, such as carbon, metal, oxides, carbides or alloys or combinations thereof, wherein a majority of the fibers: (a) are longer than 300 μm, (b) have a diameter ranging from 0.25 nm and 700 nm, and (c) are substantially crystalline, wherein the yarn has substantial flexibility and uniformity in diameter. In one embodiment, the method comprises spinning yarn by pulling fibers from a bulk material with at least one spinner that has real time feedback controls.

1. A method for the fabrication of material comprising an assembly of at least one spun yarn, said method comprising forming a yarn by spinning synthetic inorganic fibers from a bulk material, wherein said spinning is under feedback control based on a feedback signal,
wherein said spindle containing the nano-fibers is spinning relative to a take-up spindle at a relative angular velocity ranging from 30 rpm to 500,000 rpm, wherein the said angular velocity is in the axial direction of the as spun yarn, wherein the said nano-fibers are substantially aligned prior to spinning, wherein a majority of said fibers: (a) are longer than 300 μm, (b) have a diameter ranging from 0.25 nm and 700 nm, and (c) are substantially crystalline, to produce a yarn that has substantial flexibility and uniformity in diameter.
