ABSTRACT:
Synthetic filamentary yarn comprised of polyethylene terephthalate filaments which are first treated with from about 0.3 to about 0.6 weight percent based on the weight of the yarn of a liquid composition consisting essentially of about 10 to about 20 weight percent of said composition 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, about 3.0 to about 6.0 weight percent of said composition of ethoxylated tallow amine, about 10 to about 20 weight percent of said composition of ethoxylated lauryl alcohol, about 8.0 to about 12.0 weight percent of said composition of sodium salt of alkylarylsulfonate, about 1.0 to about 3.0 weight percent of said composition of dinonyl-sodium-sulfosuccinate, and about 35 to 50 weight percent of said composition of white mineral oil having a boiling point of between 510.degree. F. and 620.degree. F., and then treated with from about 0.7 to about 1.2 weight percent on said yarn of a liquid composition consisting essentially of about 13 to about 25 weight percent of said composition of a compound selected from the group consisting of glycerol monooleate and decaglycerol tetraoleate with ethoxylated tall oil fatty acids, about 12 to about 20 weight percent of said composition of a compound selected from the group consisting of sulfated glycerol trioleate and ethoxylated tallow amine, and about 55 to about 75 weight percent of said composition of a stearic acid ester of a branched chain alcohol having 14-15 carbon atoms.
