A synthetic fiber of acrylic series having an excellent animal-hair feeling is provided. The surface of the fiber having unevenness, in which the center-line mean roughness of the outer periphery of the cross-section of the fiber lies within a range of 0.01 to 0.13 mu m, is adhered thereon with an organopolysiloxane, wherein an effect by a treatment with silicone may be obtained to a greatest extent to provide the fiber having an extremely excellent animal-hair feeling. The kinds and amounts of additives to be added to a spinning solution may be so controlled that the roughness of unevenness on the surface of the fiber lies within the above range, thereby the appearance of the fiber with or without gloss may be selected. When the roughness of the surface unevenness lies within the above range and the cross-section of the fiber is a circle, or a flat or oval section having an aspect radio of 10 or less, a fiber having an extremely excellent animal-hair feeling may be obtained. |
