<p>KANEBO 58-148,612 comb. An artificial fur-like pile article is a clothlike fibrous structure provided with piles having a length of more than 10 mm, each pile composed of a non-attenuated portion where the fineness does not substantially vary in the length direction, an attenuated portion where the fineness is gradually reduced toward the top end and a fine top end, (a) the non-attenuated portion being composed of a core-sheath composite fiber having a flatness ratio of 1.5-5 and a fineness of 8-50 d, and having 1-4 wing-shaped projections in cross-section, (b) the top end being formed of an exposed core of the composite fiber and having a substantially uniform fineness of an average diameter of 5-25 .mu.m and a length of 0.3-5 mm and (c) the attenuated portion having a length of 1-15 mm. Said pile article is produced by rotating the cloth-like fibrous structure provided with cut piles having a length of more than 10 mm, which are composed of sheath-core composite fibers, each consisting of a sheath of a fiber-forming polyester and a core of thermoplastic polymer of which the decomposition rate owing to an aqueous solution of NaOH is lower than that of the polyester, and having 1-4 wing-shaped projections, a flatness ratio of 1.5-5, an average diameter of the core portion of 5-25 .mu.m and a fineness of 8-50 d fixed to a rotating body, contacting the piles with an aqueous solution of an alkali while varying the contacted length by applying a centrifugal force in a direction to which the piles are raised, to gradually attenuate the piles toward the top end, and completely decomposing and removing the sheath polymer at the top end portion.</p> |
