ABSTRACT OF THE DISCLOSURE A process is provided for improving the longitudinal and loop tenacity properties of polyamide monofilaments. The process contemplates the treating of an undrawn, spun polyamide monofilament with a vapor medium such as steam and, while the monofilament is exposed to such vapor, drawing the monofilament to a draw ratio of from 2.0:1.0 to 4.0:1.0, and further drawing the monofilament in a subsequent drawing operation to an aggregate draw ratio of from 5.0:1 to 8.0:1. The drawn products are particularly useful as reinforcing elements in rubber bodies such as tires.
