Patent abstract

The present invention provides a packing yarn that utilizes a non-metal woven reinforcement that provides lateral as well as longitudinal strength while improving the wear characteristics of the yarn material. To increase the support provided by the woven reinforcement, the yarn material and woven reinforcement are folded together such that the woven reinforcement is substantially coextensive with the yarn material in the resulting packing yarn.
