Abstract
PURPOSE: Composite fibers, consisting of eccentrically composite fibers of a polymer containing polyethylene terephthalate essentially and a polymer containing polytetramethylene terephthalate essentially, and having improved self-crimpability and dyeability.
CONSTITUTION: (A) A polymer containing 85wt% or more polyethylene terephthalate and (B) a polymer, containing 85wt% or more polytetramethylene terephthalate, and having an intrinsic viscosity satisfying formulasIand II{z is [η]of the polymer (B); y=z-x when[η]of the polymer (A) is x}are subjected to the eccentric composite spinning to give a double refraction ΔnB of the polymer (B) ≥120×10-3. The resultant fibers are then drawn to afford the aimed fibers in which the polymer (B) is capable of assuming the crystal structures α⇆β by the relaxing ⇆ stretching treatment of the fibers reversibly and positioned at the interior of the crimp spirals.
