  Textile materials having improved physical properties comprise woven and/or non-woven fiber assemblies, the fibers of which are bound to a polymer composition containing polymerized carboxylic acid ester monomers and pendant functional groups attached to a polymer backbone and having the formula: in which R1 is a divalent organic radical at least 3 atoms in length, and X is organoacyl or cyano. Such polymers markedly increase wet and dry strengths and shape retention of textile materials, and they improve other physical properties without the necessity of employing formaldehyde-releasing monomers, such as the N-methylolamides, or cross-linking agents. Methods for producing such textile materials by applying solutions or dispersions of the described polymers to fiber assemblies are also provided. Aqueous dispersions of these polymers are particularly useful forthe manufacture of loose-weaves, knits and non-wovens.
