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 R1—(CO)x—O—(CH(R2)—CH2—O)y—(CO)z—R3 wherein each of R1 and R3 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, 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 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 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; 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 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. The present spin finish composition may be used on industrial
yarn.
