Abstract
PURPOSE: To obtain ultrathin filaments having improved strength and elongation, coefficient of contraction in boiling water with good winding properties, by orienting directly undrawn polyester filaments having specific properties obtained by high- speed spinning in a specific ratio without winding them temporarily.
CONSTITUTION: A polyester (preferably polyethylene terephthalate with intrinsic viscosity 0.55W0.7) is spun by a hole diameter preferably 0.1W0.2mm, spinning temperature 290W305°C, spinning draft 200W700, drawing speed of spun filaments 2,500W4,000m/min, to give undrawn polyester filaments Y having double refractive index 80W10-3W120×10-3, coefficient of contraction in boiling water 20W60%, single filament denier not more than 1d. In the operation, the spinning drawing roller 3 is heated to 70W150°C, and the filaments Y are oriented continuously 1.05W 1.6 times and heat-treated using the orientation roller 5 heated at preferably 85W 200°C without winding them temporarily.
