Abstract
PURPOSE: To obtain the titled fibers having improved dimensional stability at a high temperature with the good fiber making property, by mixing polyethylene terephthalate (PET) with a polyester polymer exhibiting a flow birefringence under specific conditions, and melt extruding the resultant mixture.
CONSTITUTION: (A) A polyethylene terephthalate (PET) having a reduced viscosity of 0.7W1.5 is mixed with (B) a polyester polymer, exhibiting a flow birefriengence under a slight shear rate ≤10/sec on melting or fluidizing by heating, and having a flow temperature between 250 and 350°C and a reduced viscosity ηsp/c=about 0.1W4.0, e.g. polyester polymer expressed by the formula (R is H, Cl, CH3, etc.; a=0.45W0.50; b=0W0.05; c=0.45W0.10; d=0W0.40; e=0W0.15; f=0W0.5; and a+b=c+d+e; the sum of aWf=1), in an amount of 1W30PHR, and the resultant mixture is then melt extruded to give the titled fibers having an aspect ratio of the dispersed component (B) ≥2.5 (ratio between the length in the long direction of the fibers and the length in the direction perpendicular to the direction of the fibers) and a degree of crystal orientation ≥80%.
