The Physical Properties of Composite Yarns Produced by an Electrostatic Filament-charging Method

Abstract

A technique is described for the separation of the individual filaments of a continuous-filament yarn. This involves the yarn's being treated with a small amount of Permalose TM anti-static agent and the induction of electrostatic charges onto the individual filaments. The separated filaments are intermingled with a drafted ribbon of fibres at the front-roller nip of a ring-spinning frame, to produce 20-tex 70/30 cotton/polyester-fibre filament-blended composite yarns in which a degree of mixing between Fibres and filaments was achieved. Cotton ring-spun and the equivalent core-spun yarns were also made to compare their physical properties with those of the composite yarns. Twist, fibre length, and the roving-feeding arrangement were varied to observe their influence on the yarn properties.
