A paper machine substrate modified to resist contamination by adhesive materials. The paper machine substrate includes: a paper machine substrate; and an active agent that is grafted to the surface of the paper machine substrate to lower the surface energy of the paper machine substrate so that the substrate resists contamination by adhesive material. The papermachine substrate may be made by a process that includes the steps of: providing a paper machine substrate; applying an active agent to the paper machine substrate; and exposing the paper machine substrate to greater than about 2 million rads (Mrad) of radiation to cause a reaction between the active agent and the substrate so the active agent becomes joined to the substrate. The active agent may be a fluorinated monomer, a fluorinated polymer, a perfluorinated polymers, or a polyalkyl siloxane.

1. A paper machine substrate for transporting fibers during a papermaking process, wherein an active agent selected from the group consisting of fluorinated monomers, fluorinated polymers, perfluorinated polymers, and polyalkyl siloxanes is grafted to the surface of said paper machine substrate to lower the surface energy thereof so that said paper machine substrate resists contamination by adhesive materials, wherein the percent add-on of said active agent to said substrate is from about 0.5% to about 5%.
