A cover fabric for a V belt having increased flex and wear-life, and a method of making the cover fabric. A fabric is bias cut into a continuous strip of fabric. The individual fibers in the continuous strip are impregnated with an elastomeric polymeric material effective to increase the flex and wear-life of the fabric when used as a cover fabric for V belts. This impregnation is accomplished by immersing the strip in a fluid mix having a viscosity of about 2000 cps or less, the mix including a fluid carrier, an elastomeric polymer (e.g. a polychloroprene compound) and a dark pigment. A coating of an elastomeric polymer (e.g. another polychloroprene compound) is applied to the strip, the strip is stretched in its width direction to increase the angular relation of the threads of the fabric relative to its longitudinal axis, and the thus coated strip is dried. The continuous strip is ultimately slit longitudinally of itself into a plurality of tapes, and the tapes are used to cover a V belt.
An industrial cover fabric for power transmission belts or the like, consisting of a strip of bias cut fabric woven from blended fiber yarns, the individual fibers of said yarns being encapsulated in a dried pigmented elastomeric polymer, and said yarns and encapsulated fibers being over coated with a dried elastomeric polymer, the angular orientation between the warp and weft yarns of said woven fabric being increased to an angle greater than 90.degree. and being held in that position by the dried elastomeric coating, said industrial cover fabric having greatly increased wear life by virtue of said individual fiber encapsulation, the pigment in said pigmented elastomeric polymer being adapted to abrade off with said polymer to reveal unpigmented portions of said fibers when said fabric has outlived its usefulness.
A bias cut woven fabric cover for a V belt or the like, the fabric cover being produced from a continuous fabric strip by impregnating the individual fibers in the strip with a fluid mix including an elastomeric polymer, a dark pigment and a fluid, and having a viscosity of about 2000 cps or less;
A bias cut woven fabric cover for a V belt or the like, the fabric cover being produced from a continuous fabric strip by impregnating the individual fibers in the strip with an elastomeric polymeric material effective to increase the wearlife of the fabric when covering a V belt or the like, applying an elastomeric coating to the strip, and drying the thus coated strip.
