PURPOSE:To reduce the frequency of peeling a peelable component in a drawing step, by spinning and drawing peelable conjugate fibers of a polyamide and polyester under specific conditions. CONSTITUTION:A peelable conjugate fiber yarn 5 of a polamide and polyester is taken off at 2,500-8,000m/min, preferably 3,000-7,000m/min spinning speed and, without winding once, is continuously drawn under conditions of the drawing temperature (TD) and raw ratio (r) satisfying the formulas Tg<=TD<=Tm-20, preferably Tg+10<=TD<=Tm-30 and 1.05<=r<=2.5, preferably 1.10<=r<=2.25 (Tg and Tm are glass transition temperatures and meling points of the polyester or polyamide; TD is the range satisfying the above-mentioned values of both polymers). Preferably, the draw ratio (r) is set to give within 15-65%, preferably 20-55% range residual elongation of the drawn yarn.
