SYSTEM AND METHODS FOR SPINNING CARBON NANOTUBES INTO YARN, AND YARN MADE THEREFROM

摘要

A system and method for processing of carbon nanotubes (CNTs) to form a structured longitudinal arrangement, or base yarn, is disclosed. A CNT array having a multiplicity of CNTs arranged on a substrate and several methods for removal are further disclosed. Also included are a drafter for aligning and drafting the CNTs to form a sliver, a spinning apparatus, including at least one twist zone for providing rotation to the CNTs or sliver to produce a twisted, diametrically- condensed, longitudinal orientation of the CNT fibers; and take-up for collecting the yarn. Preferably the system for processing CNTs to form a structured longitudinal arrangement is a spinning process; more preferably, it is an electromagnetic (EM) spinning process.
