Abstract
A nanofiber forest on a substrate can be patterned to produce a patterned assembly of nanofibers that can be drawn to form nanofiber sheets, ribbons, or yarns.

1-469. (canceled)
A nanofiber yarn comprising a plurality of nanofibers twisted into a yarn along an alignment axis, wherein
- (a) the nanofibers of the plurality of nanofibers have a ratio of nanofiber length to nanofiber circumference of at least 50;
- (b) the yarn has a helix angle measured relative to the alignment axis of from 50 to 30°;
- and
- (c) the yarn has tensile strength of at least 280 MPa.

A nanofiber fabric comprising:
- (a) a first sheet of multiwalled nanotubes, wherein the multiwalled nanotubes of the first sheet are aligned in a first direction;
- and
- (b) a second sheet of multiwalled nanotubes on the first sheet of multiwalled nanotubes, wherein
- (i) the multiwalled nanotubes of the second sheet are aligned in the first direction,
- (ii) the first sheet and the second sheet are aligned so that the multiwalled nanotubes of the first sheet and the second sheet are both aligned in the first direction.
