Conjugate fibers which are easy to make into fibers of small denier and soft, have a good feel and adequate strength and consequently are suitable for use as the material for various applications and non-woven fabrics comprising the said conjugate fibers. The conjugate fibers at least a part of which comprise a propylene polymer having a molecular weight distribution (Mw/Mn) of 1.5 to 3.5, and non-woven fabrics made thereof. The propylene polymer may, preferably, be a polymer obtained by a single site catalyst. The conjugate fibers may have a core-sheath structure containing core parts comprising the propylene polymer and sheaths comprising an ethylene polymer, or have a side-by-side structure containing the fiber part comprising the propylene polymer and the fiber part comprising an ethylene polymer. |
