Abstract
PURPOSE: A specific drawing mechanism, drawing conditions, and methods are applied to effect uniform drawing with reducing uneven stretch breaking, thus producing high quality slivers for spinning with high uniformity without disturbing the uniformity of undrawn tows.
CONSTITUTION: An undrawn tow 2 of polyethylene terephthalate is subjeted to the first-step drawing in which the tow is fed through tow regulator 3 and the temperature of the draw pin between feed rollers 4 and drawing rollers 8 is set to 100W140°C and the draw ratio is set to 85W95% of the maximum one at which uniform drawing operation can be conducted. The second-step drawing is effected by adjusting the temperature of second draw pin 9 between the draw rollers 8 and the second draw rollers 11 to 130W170°C and stretching the tow at a draw ratio of less than 1.20 so as to arrange drawing points on one line. Immediately after the second drawing, the resulting tow is heat treated under tension uniformly using set pin 10 heated up to 170W230°C. Without stopping the advance, the tow is cut by stretch breaking by use of roller 12, passed through adjust rollers 13 and 14 and made into sliver 15.
