The invention provides a bicomponent staple fiber comprising poly(ethylene terephthalate) and poly(trimethylene terephthalate) wherein the bicomponent fiber has a substantially oval cross-section shape having an aspect ratio A:B of about 2:1 to about 5:1 wherein A is a fiber cross-section major axis length and B is a fiber cross-section minor axis length, a polymer interface substantially perpendicular to the major axis, a cross-section configuration selected from the group consisting of side-by-side and eccentric sheath-core, a tenacity at 10% elongation of about 1.1 cN/dtex to about 3.5 cN/dtex, a free-fiber length retention of about 40% to about 85%, and a tow crimp development value of about 30 to 55%, and a spun yarn comprising the bicomponent staple fiber.
