No-Twist Cotton Yarn Made from Card Web1

Abstract

A technique for producing a no-twist yarn from a card web has been developed. The fibers in a strip of web are aligned by a special drafting device. The fibers are impregnated with a binder, dried, and packaged. The binder holds the untwisted fibers together until the yarn is made into a fabric. The binder is then removed, and the fibers are held together by the fabric construction. Fabric properties including strength compare favorably with fabric properties of conventional yarns. A yarn production rate of 1 m/s has been achieved.
