ABSTRACT:
The invention provides an improved partially oriented polyester yarn finish which consists essentially of from about 50 to about 90 weight percent of one or more high molecular weight ethylene oxide/propylene oxide copolymers having an ethylene oxide content such that the ethylene oxide in the copolymer constitutes less than about 25 weight percent of the finish; from about 10 to about 35 weight percent of one or more alkyl chain based lubricants, a major amount of which has a smoke point within the range of from about 155.degree. C. to about 200.degree. C.; and an emulsifying amount of base neutralized fatty acid such as potassium oleate.
