PROBLEM TO BE SOLVED: To obtain an oily agent for an elastic fiber, less in sticking property and excellent in reeling quality. SOLUTION: This oily agent for an elastic fiber uses at least one kind of polyalkylene ether-modified polysiloxane having 10-40 centistokes (25 deg.C) viscosity selected from a group of polyethers having 20-80wt.% polyoxyethylene skeleton and 2-20 number of Si atoms in a molecule and expressed by formula I [X<1> is a trialkylsilyl or Y<2> ; Y<1> , Y<2> are each formula IV; R<1> , R<2> are each monovalent hydrocarbon; (m) is 0-15], formula II [X<3> is a trialkylsiloxane or Y<2> ; X<2> is a trialkylsilyl; Y<1> , Y<2> , R1 are each same as above; (n) is 0-10], formula III (X<2> , X<3> , Y<1> , Y<2> are each same as above; (k) is 0-7] and formula IV [X<4> , X<5> are each monovalent hydrocarbon or a trialkylsiloxane; R<3> is H or an alkyl; A is ethylene and/or propylene; 0A is an oxyethylene and/or an oxypropylene; (p) is 1-50; (q) is 1-4]. |
