Yarns having a spin finish composition thereon comprising at least about 10 percent by weight based on the spin finish composition of components (a) and (b) having the formula R1(CO)x-O-(CH(R2)-CH2-O)y-(CO)zR3, wherein each of R1 and R3 is selected from the group consisting of hydrogen or an allyl 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, R2 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 fiom 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 R2 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; (c) an alkoxylated silicone; and at least about one percent by weight based on the spin finish composition of component (d) having the formula R4 (CH2O(CO)aR5)b wherein R4 is -C-or -COC-; a is 0 or 1; R5 is -H; from -CH3 to -C18H37; or -CH(R6)-CH2O; b is 4 or 6; and R6 is -H or -CH3 or -H and -CH3 in a ratio of 10:90 to 90:10.
