Abstract: Conventional heat stretching and/or setting conditions for fabrics made of heat sensitive thermoplastic yarns such as polyester, and even special techniques advanced in prior patents, have been found in adequate to produce coated abrasives with sufficient elongation resistance for some very heavy duty service. A superior alternative is provided by encasing the yarns in the backing in a thermosetting adhesive and then curing it while mechanically restraining the yarns from shrinking, as they would under the temperature conditions employed for cure if no restraint were used. The method is also applicable to other types of yarn reinforced web materials for which a combination of elongation resistance and flexibility is needed.
