ABSTRACT:
Spin finish composition for conventional speed spinning of polyester yarns providing yarn of superior quality, low emissions and no significant deposits on processing equipment, is a non-aqueous composition consisting essentially of from 10 to 70% by weight of a trimethylol or tetramethylol C.sub.1 -C.sub.3 alkane ester wherein all the methylol groups are esterified with C.sub.8 -C.sub.10 saturated carboxylic acid, preferably trimethylol propane tripelargonate, from 10 to 70% by weight of tetraethylene glycol diester of C.sub.8 -C.sub.10 saturated carboxylic acid, preferably tetraethylene glycol diester of decanoic and octanoic acid, from 5 to 50% by weight of low volatility, light viscosity, 15 low surface tension, substantially aromatic-free light mineral oil, preferably consisting essentially of C.sub.12 -C.sub.15 isoparaffic hydrocarbon, and from 2 to 20% by weight of 1H-imidazolium, 1-ethyl-4,5-dihydro-3-(2-hydroxyethyl)-2-(8-heptadecenyl)-, ethyl sulfate. Compositions with viscosities of greater than 17 as determined with a Brookfield viscometer at 20.degree. C. are heated 40 to 90.degree. C. but below the flash point of any component to reduce the viscosity to provide a reduced viscosity composition for application to polyester yarns.
