Abstract

A spinning nozzle for synthetic linear high polymers has a plurality of narrow elongated slots of equal length radiating from a common central aperture, so as to produce filaments of lobed cross-section. The sides of the slots may be straight or curved. Fig. 1 shows a suitable <PICT:0779822/IV(a)/1> <PICT:0779822/IV(a)/2> shaped orifice and Fig. 2 the resulting filament. The number of indentations and their relative sizes may vary. Suitable synthetic high polymers include polyamides, polyesters and polyurethanes. The filaments are preferably passed through cooled air or liquid on leaving the spinning jet whereby the sharpness of the profile is preserved. The lustre of the shaped filaments may be further reduced by twisting.
