Abstract
PURPOSE: To obtain the titled fibers, having improved strength, Young's modulus, etc. and heat shrinkage, and usable for industrial applications, by mixing polyethylene terephthalate (PET) with a polyester having the ability to form the melt anisotropy, and melt extruding the resultant mixture.
CONSTITUTION: (A) 99.5W70wt% polyethylene terephthalate (PET) having a reduced viscosity of preferably 0.7W1.5 is mixed with (B) 0.5W30wt%, preferably 1W15wt%, polyester having a flow temperature between 250 and 350°C and the ability to form the melt anisotropy, e.g. polyester capable of forming the optically anisotropic phase (liquid crystal phase) on heat melting, and melt extruded to give the aimed fibers having an aspect ratio of the dispersed component (B) ≥1.5 (ratio between the length in the long direction of the fibers and the length in the direction perpendicular to the long direction of the fibers) and a degree of crystal orientation of at least 80% measured by the X-ray diffractometry. The components (A) and (B) may be melt extruded while mixed with each other.
USE: Tire cords, etc.
