Abstract
Ester lubricant compositions are provided which provide a good balance of lubricity and emulsifiability. The esters are derived from polyoxyalkylene glycols with a dibasic acid mixture consisting of dimer acids and short-chain dibasic acids. The emulsions and clear, homogeneous lubricant solutions provide excellent spin finishes for fibers such as polyamides and polyesters.
