Abstract
A spin fiber lubricant composition is disclosed. The composition is essentially comprised of a liquid carrier having therein an ester of the general structural formula (I): ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are hydrocarbyl groups preferably in the form of alkyl groups containing 1-6 carbon atoms. The composition has been found to be useful in connection with providing materials with lubricating properties which are desirable for the spinning of fibers.
