PROBLEM TO BE SOLVED: To form a nonwoven fabric, a knitted or woven fabirc or a fiber forming body having good uniformity by using a highly smoothing fiber, obtained by applying a specific resin mixture composition to the surface of a thermoplastic fiber SOLUTION: An alkylphosphoric acid salt having a 6-14 average carbon number and/or a polyoxyalkylene adduct to an alkylphosphoric acid salt of a 10-22 average carbon number in an amount of 50-85wt.% is blended with 15-50wt.% of an amide group-containing polyoxyalkylene-modified silicone to prepare a smoothing agent. This, agent in an amount of 0.1-2.0wt.% is applied to a conjugate short fiber having <=30mm fiber length so as to arrange that at least a part of the fiber surface is formed by using a polyolefin-based resin, a polyester-based resin, a polyamide-based resin or on ethylene-acrylic ester- maleic anhydride terpolymer all having <=120 deg.C melting point as at least one component of the fiber and a thermoplastic resin having a melting point which is 20 deg.C higher than those of the above components is contained as the other component to provide the object fiber having high smoothness. |
