Abstract
Abstract In a primary backing woven from synthetic yarns for tufted fabrics and other products, such as carpet and the like, an enhancement in the carpet and/or tufted fabrics tuft raveling resistance capabilities is obtained when the backing is coated with a polymeric substance which effectively reduces such tuft raveling to an acceptable degree. The preferred coating material is a copolymer of ethylene vinyl acetate, and is applied to the backing by any known method including spraying, immersing, brushing or rolling.
