Abstract

1,189,393. Orientated synthetic filaments. SOC. RHODIACETA. 12 June, 1968 [16 June, 1967], No. 28013/68. Heading B5B. Orientated synthetic filaments are produced in a continuous series of operations wherein continuous filaments are extruded from a molten mass of linear synthetic polymer and are (a) cooled to a temperature of T 1 , which is above 50‹ C., and at least 5‹ C. above the second order transition temperature of the polymer, but not greater than the initial orientation temperature, (b) positively forwarded at a speed V 1 higher than the extrusion speed, (c) brought to a temperature T 2 which is between T 1 and ambient temperature and (d) positively forwarded at a speed V 2 which is greater than V 1 . The process can be applied to condensation polymers such as polyamides and copolyamides obtained by condensation of diacids and diamines, e.g. polyhexamethylene adipamide, or aminoacids, e.g. polyundecanamide, or by polymerization of lactams, e.g. polycapronamide and polyesters such as polyethylene terephthalate and copolyesters comprising at least 75% of ethylene terephthalate units in the chain. The apparatus shown comprises a spinneret, a yarn supply system comprising driven rolls 1 and 2, a driven stretching roll 3 with an associated idler roll 4, an applicator roll 5 which contacts the filaments as they pass between rolls 3 and 4 and transfers a finish to them from the bath, guide rolls and a winding up station.
