Abstract:
1. A process for producing a yarn comprising nanofibers, the process comprising the steps of: (a) providing a pre-primary assembly, wherein the pre-primary assembly comprises a forest of substantially parallel nanofibers aligned in a first direction; (b) drawing laterally from a sidewall of the forest to provide a primary assembly of the nanofibers having an alignment axis extending laterally from the forest about which twisting can occur, wherein the direction of drawing and the alignment axis are at an angle to said first direction of between 60° and 90° ; and (c) twisting the primary assembly about the alignment axis of said primary assembly to produce a twisted yarn, wherein the primary assembly progressively converges into the twisted yarn as a nanofiber ribbon wedge extending laterally from a wedge base at said sidewall of the forest of substantially parallel nanofibers in the pre-primary assembly.
