Aqueous polymer dispersion composition and method of adhering textile materials

A method comprising:

• applying a composition to a tufted primary backing material, wherein the primary backing material has a first primary surface and a second primary surface, wherein tufts extend outwardly from the first primary surface and loop backs are formed on the second primary surface, and wherein the composition is applied to the loop backs and second primary surface of the tufted primary backing material, the composition comprising:
• an aqueous dispersion of colloidal thermosetting polymer particles;
• and
• thermoplastic polymer particles dispersed in the aqueous dispersion, wherein the thermoplastic polymer particles have an average particle size of approximately 200 microns to approximately 1,000 microns;
• heating the tufted primary backing material and composition to remove water therefrom and to melt the thermoplastic particles;
• applying pressure to the thermoplastic polymer particles on the second primary surface of the tufted primary backing material so that the thermoplastic polymer particles are formed into a film;
• and
• allowing the primary backing material to cool.
