Abstract

1,174,867. Synthetic fibres. TOYO RAYON K.K. 16 June, 1967 [18 June, 1966], No. 27835/67. Heading B5B. [Also in Division D1] In a direct spinning and drawing process for preparing serviceable fibres having improved tenacity, elongation, and dimensional stability, a fibre-forming thermoplastic polymer, such as polyamide, polyester or polyolefin, is melt spun and the as-extruded filaments are subsequently drawn without winding them up as a package, and then wound as a package, the speed of the as-extruded filaments being maintained at 150 to 350 m./min. and the temperature of the filaments being maintained between the glass transition temperature for the polymer used and 70‹ C. above that temperature at the start of drawing, the drawing ratio being 3-5 to 5. The drawn filaments may be twisted in known manner whilst being wound up, or they may be given a false twist and heat set simultaneously with the drawing. In one embodiment (Fig. 2) the polymer extruded from the spinneret 1 reaches drawing roller 3 after passing round a heated roller 2 and a false twister 5, and is collected on a wind-up bobbin 6. Rollers 2 and 3 rotate at different speeds to give the desired draw ratio, and the temperature and speed of roller 2 is maintained within the limits specified above. A hot plate 7 may be provided between roller 2 and the false twister to set the twisted structure of the filaments.
