The present invention provides an article formed by impregnating a fibrous structure with a compound, the compound including an aqueous dispersion, the dispersion having (a) at least one polymer selected from the group consisting of an ethylene-based thermoplastic polymer, a propylene-based thermoplastic polymer, and mixtures thereof; (b) at least one polymeric stabilizing agent; and (c) water; and removing at least a portion of the water from the impregnated fibrous structure. The present invention also provides a method of forming a stiffened textile. The method may include the steps of: forming a compound, the compound including an aqueous dispersion having (a) at least one polymer selected from the group consisting of an ethylene-based thermoplastic polymer, a propylene-based thermoplastic polymer, and mixtures thereof, (b) at least one polymeric stabilizing agent, and (c) water; impregnating a textile with the compound; and removing at least a portion of the water from the impregnated textile.
