Patent number: 9481962Abstract: The invention is directed to a method for treating a textile material with a crosslinkable high density polyethylene based elastomer compound, such treated material for use in reinforced elastomeric articles. In one embodiment, a crosslinkable high density polyethylene based elastomer compound is applied in particle form to a surface of a textile material having a plurality of interstices. The particles are of a size no greater than about 35 mesh and include a peroxide curing agent. Next, the particles are melted so as to impregnate the interstices of the textile material with the compound. Then, the compound is crosslinked in-situ via the peroxide curing agent. In one example, the rubber compound includes about 80 parts per hundred cross-linkable material (phcm) to 100 phcm crosslinkable high density polyethylene. The resulting textile material may be used as a facing fabric, e.g., in a reinforced elastomeric article, such as a toothed power transmission belt.Type: GrantFiled: February 11, 2008Date of Patent: November 1, 2016Assignee: Veyance Technologies, Inc.Inventor: Douglas Wood
