Abstract
A highly filled yarn is formed by melt spinning a thermoplastic fibre-forming polymer containing at least 25% by weight of a particulate filler through a spinneret to form a continuous multi-filament yarn. The filaments are drawn away from the spinneret at a rate sufficient to orientate the yarn at least partially. The filaments pass around a guide between the spinneret and the draw means; the direction of travel of the filaments is diverted by means of the guide through an angle of at least 30.degree.. The yarns produced have increased strength and decreased extensibility.
