PURPOSE:To provide the subject fiber excellent in anti-sticking-property and loosing property and exhibiting good bucking resistance by supplying an oil composition comprising a silicone, a silicone resin and a modified polyorganosiloxane and having a specific viscosity for the polyurethane fiber when the fiber is spun and wound up. CONSTITUTION:When a polyurethane fiber is spun and wound up on a bobbin, the fiber is oiled with an oil composition to provide the polyurethane elastic fiber excellent in anti-sticking property, loosing property and bucking resistance and free from the generation of scums, the oil composition comprising (A) a polyorganosiloxane (silicone oil) or a mineral oil, (B) a silicone resin and (C) an ether-modified polyorganosiloxane (e.g. polydimethylsiloxane modified with ethylene oxide and/or propylene oxide) and having a viscosity of <=50 cst at 30 deg.C. |
