Abstract

A single measurement of twist is insufficient to typify open-end yarns because the twist (tpi) of the fibers comprising the yarn core is different from those comprising the outer sheath, and both are usually lower than the machine value. The differences may be expressed in terms of a twist gradient which is a function of machine design, operating conditions, and fiber characteristics. In these experiments the differences were particularly marked with high polyester blends.
