In a process for producing polyethylene terephthalate yarn wherein a liquid finish is applied to the yarn, said process involving spinning and drawing steps, the improvement comprising first applying to the yarn prior to said drawing step a liquid finish composition consisting essentially of a polyalkylene glycol compound which is a mixed polyoxyethylated-polyoxypropylated monoether prepared in accordance with the equation: ##STR1## where R is an alkyl group having 1 to 8 carbon atoms, x and y are the number of moles of propylene oxide and ethylene oxide respectively and wherein ethylene oxide comprises 40 to 60 percent by weight of the combined total of ethylene oxide and propylene oxide and x+y has a value to produce a molecular weight of from 300 to 1,000, and then applying to said yarn after said drawing step a liquid finish composition consisting essentially of about 70 to 95 parts by weight of said mixed polyoxyethylated-polyoxypropylated monoether, about 5 to 30 parts by weight of a silane having the structural formula: ##STR2## wherein n =2 to 5, and a sufficient amount of a water-soluble alkaline catalyst to adjust the pH of the finish composition to 8-10.
