Abstract
The present invention is directed toward a method for improving the tuft bind of yarn in textile coverings. The method comprises applying to the yarn, prior to applying an adhesive, a functional amount of an aqueous dispersion comprising a surfactant and/or polymeric component wherein the aqueous dispersion has a surface tension approximately equal to or less than the surface tension of the yarn. The present invention also is directed toward a textile covering having improved tuft bind prepared by the aforementioned method. The method is advantageously employed in the preparation of floor coverings to maintain the original appearance and resist the loss of pile or a condition known as pill and fuzzing.
