The present spin finish composition comprises at least about 10 percent by weight based on the spin finish composition of components (a) and (b) having the formula <?in-line-formulae description="In-line Formulae" end="lead"?>R<SUB>1</SUB>-(CO)<SUB>x</SUB>-O-(CH(R<SUB>2</SUB>)-CH<SUB>2</SUB>-O)<SUB>y</SUB>-(CO)<SUB>z</SUB>-R<SUB>3</SUB><?in-line-formulae description="In-line Formulae" end="tail"?> wherein each of R<SUB>1 </SUB>and R<SUB>3 </SUB>is selected from the group consisting of hydrogen or an alkyl group having from one to 22 carbon atoms or an alkylene hydroxy group having from one to 22 carbon atoms, x is zero or one, R<SUB>2 </SUB>may vary within component (a) or component (b) and is selected from the group consisting of hydrogen or an alkyl group having from one to four carbon atoms, y is zero, or from one to 25, and z is zero or one, in component (a), x and z are equal to zero and the average molecular weight of component (a) is less than or equal to 1,900 and if R<SUB>2 </SUB>varies, component (a) is a random copolymer; and in component (b), at least x or z is equal to one or component (b) is a complex polyoxyethylene glyceride-containing compound having greater than 10 polyoxyethylene units; up to about five percent by weight based on the spin finish composition of component (c) of an ethoxylated silicone; and at least about one percent by weight based on the spin finish composition of component (d) having the formula <?in-line-formulae description="In-line Formulae" end="lead"?>R<SUB>4</SUB>(CH<SUB>2</SUB>O(CO)<SUB>a</SUB>R<SUB>5</SUB>)<SUB>b</SUB><?in-line-formulae description="In-line Formulae" end="tail"?> wherein R<SUB>4 </SUB>is -C- or -COC-; a is 0 or 1; R<SUB>5 </SUB>is -H; from -CH<SUB>3 </SUB>to -C<SUB>18</SUB>H<SUB>37</SUB>; or -CH(R<SUB>6</SUB>)-CH<SUB>2</SUB>O; b is 4 or 6; and R<SUB>6 </SUB>is -H or -CH<SUB>3 </SUB>or -H and -CH<SUB>3 </SUB>in a ratio of 10:90 to 90:10. The present spin finish composition may be used on industrial yarn.
