Abstract: 1,187,710. Non-circular filaments. SNAM PROGETTI S.p.A. 19 Dec., 1968 [22 Dec., 1967], No. 60516/68. Heading B5B. [Also in Division D1] A melt-spun filament has a cross-section in the form of, or substantially in the form of, two similar or different circular segments joined on opposite sides of a straight common line formed by the chords of the segments, with the proviso, that one chord does not completely overlap the other. The chords may be of equal or of unequal length and have a common point or one chord overlaps up to 90% of the other chord or the shorter chord. The filaments are produced using a spinneret plate comprising a plurality of extrusion orifices each having a cross-section, taken in the plane parallel to the extrusion face of the spinneret plate in the form defined above. In an example melt spun filaments of polyethylene terephthalate are gathered in a tow and stretched in two stages to increase their degree of crystallinity and molecular orientation. In the first stage the tow is fed from a heated roller trio through a zone heated by an infra-red radiation plate and through a roller octet having a peripheral speed higher than that of the feed rollers. The tow then contacts a heated stainless steel plate and passes a third device the speed of which is equal to that of the stretching device, thus increasing the tension of the tow.
