ABSTRACT:
It has been suggested that certain polyglycol ethers, in particular mixed polyoxyethylated-polyoxypropylated monoethers, are useful as spin finishes in the production of polyester tire yarns. Polyglycol ethers having a relatively low molecular weight of about 300 to 1,000 make the best lubricants; however, their effectiveness is significantly diminished by volatilization loss during high temperature processing of the tire yarn. It has now been found that said volatilization loss is greatly decreased by including in the finish a small percentage of certain antioxidant compounds. The particular antioxidant compound used has been found to be very critical.
