Abstract
Synthetic filamentary yarn comprised of polyethylene terephthalate filaments which are first treated with a liquid composition consisting essentially of refined coconut oil, about 10 to 20 weight percent of said composition of a stearic acid ester of a branched chain alcohol having 14-15 carbon atoms, ethoxylated tallow amine, ethoxylated lauryl alcohol, sodium salt of alkylarylsulfonate, dinonyl-sodium-sulfosuccinate, and white mineral oil having a boiling point of between 510.degree. and 620.degree. F., and then treated with a liquid composition consisting essentially of a compound selected from the group consisting of glycerol monooleate and decaglycerol tetraoleate with ethoxylated tall oil fatty acids, a compound selected from the group consisting of sulfated glycerol trioleate and ethoxylated tallow amine, and a stearic acid ester of a branched chain alcohol having 14-15 carbon atoms.
