PURPOSE: To obtain a composite combined filament yarn capable of providing fabric rich in air-including property and excellent in swelling property and wool-like feeling by weaving the yarn. CONSTITUTION: This conjugated yarn is composed of >=2 polyester multifilament yarns, and a monofilament (a) of at least one yarn A thereof has crimp tendency and in other at least one yarn B, a part different in double refractive index is randomly distributed in the longitudinal direction of the monofilament (b) within the range of double refractive indexΔn of 0.01-0.12 and plural monofilaments intermittently alternately form a crimp part and non-crimp. Further, all multifilament yarns constituting conjugated yarn are blended and interlaced without substantially having the difference of yarn length.
