Abstract
A low melting, high solids spin finish composition is provided that can be readily applied to synthetic fibers during the fiber-making process. The spin finish solids, which make up at least about 70% by weight of the spin finish composition, comprise nonionic hydrocarbon surfactant components, such as polyoxyalkylenes, which have a <HLB> value of from about 2 to 13 and a melting point within the range of about 25° C. to about 140° C. In some embodiments, the spin finish composition also includes select fluorochemicals.
