ABSTRACT:
An improved multifilament polyethylene terephthalate yarn is prepared by first applying to the yarn a liquid composition comprising hexadecyl stearate, refined coconut oil, ethoxylated tallow amine, ethoxylated lauryl alcohol, sodium salt of alkylarylsulfonate, dinonyl-sodium-sulfosuccinate, and a mineral oil, and then applying to the yarn a liquid composition which is an oil-in-water emulsion, the oil portion of which comprises coconut oil, polyoxyethylene hydrogenated castor oil, and phosphated polyoxyethylated tridecyl alcohol neutralized with potassium hydroxide. The yarn is preferably used in tire cords for the construction of pneumatic passenger tires and results in excellent adhesion of tire cord to rubber.
