1,268,908. Melt spinning aromatic polyesters. IMPERIAL CHEMICAL INDUSTRIES Ltd. 28 April, 1970 [23 May, 1969], No. 26429/69. Heading B5B. In a process for spinning an aromatic polyester comprising :-(a) extruding a filamentary stream at a controlled linear speed in the molten state, (b) cooling such stream from its initially molten state through an intermediate plastic state to a solid state, and (c) hauling off such solidified filament at a higher controlled linear speed, a method of reducing the optical birefringence of such solidified filament comprises: (i) applying a forwarding force to such filamentary stream in a region in which it is in such intermediate plastic state, (ii) the forwarding force being sufficiently small such that the filament tension between the point of application of the forwarding force and the point of hauling off is always positive. The forwarding force may be applied by at least one driven roller, which may be heated. The forwarding force may be applied by a fluid drag, e.g. by an air ejector. The polyester may be polyethylene terephthalate. As shown in Fig. 1 of the drawings, a spinning pack 11 with a spinneret 12 at its base, extrudes filamentary streams 13 which at first are subjected to delayed cooling in the region 14 which is partially enclosed in the thermostated box 15 used to heat the pack 11.
