ABSTRACT:
A fiber finish composition, a process for treating polyester yarn therewith and polyester yarn so treated are all disclosed. The fiber finish composition, which is preferably applied as an overfinish to the yarn subsequent to drawing of the yarn, comprises about 60 to 90 weight percent of water; about 0.3 to 10 weight percent of gamma-glycidoxypropyltrimethoxysilane; about 0.05 to 4.0 weight percent of a catalyst selected from the group consisting of urea and a solution of a cobalt, stannous, iron, nickel, zinc, manganese or chromium salt of 2-ethylhexoic acid or lauric acid in a carrier which is miscible in water; and about 6.5 to 38.6 weight percent of a compatible noncontinuous phase. The catalyst, alternatively, may form 0.00025 to 0.8 weight percent of the composition when selected from the group consisting of cobalt, manganese, iron, nickel, chromium, tin and molbydenum salts of a mono- or polyfunctional organic acid wherein each acid function moiety has 4 to 30 carbon atoms; the catalyst in this instance is added to the nonaqueous portion of the overfinish prior to formation of the oil in water emulsion. The yarn is preferably used in reinforcing rubber, for example in cords for the construction of pneumatic passenger tires or conveyor belts, and results in excellent adhesion of the cord to rubber.
