WIPO Patent Application WO/2000/060158
Kind Code:
A2
Abstract:
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 R¿1?-(CO)¿x?-O-(CH(R¿2?)-CH¿2?-O)¿y?-(CO)¿z?-R¿3? wherein each of R¿1? and R¿3? 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¿2? 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¿2? 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; and up to about five percent by weight based on the spin finish composition of component (c) of an ethoxylated silicone. The present spin finish may be used on industrial yarn.
