Composite modified cross section fiber

Abstract

Abstract PURPOSE: The titled fiber having a silky luster and hand, and obtained by the composite spinning of an oriented copolymer of polyethylene terephthalate and a component containing a metal sulfonate arranged in a specific constitution. CONSTITUTION: (A) Polyethylene terephthalate 1 and (B) polyethylene terephthalate 2 containing 0.5W3mol% a metal sulfonate, preferably 5-sodium sulfo isophthalate, are arranged in the position of symmetry of rotation, and subjected to composite spinning to give a fiber, which is then woven or knitted and treated with an aqueous solution of NaOH etc. to elute preferably 10W30wt% the original weight of the fiber and give the aimed modified cross section fiber having protruded and recess parts.
