ABSTRACT:
A process is described for improving the ammonolytic stability of polyester textile yarn without substantial loss of its tensile strength which comprises exposing separated fibers of the yarn to corona discharge for a total of about 0.01 to 3 seconds at a speed of at least 100 feet per minute and then reforming the yarn. A cord made from this yarn is described, as well as a tire produced by bonding the cord to rubber.
