Abstract
A cushioned carpet tile is provided. The cushioned carpet tile includes a primary carpet fabric having a plurality of pile-forming yarns projecting from one side thereof. A mass of polymer cushioning is dispersed on the side of the primary carpet fabric from which the pile-forming yarns do not extend. A heat-fused nonwoven backing of polyester and polypropylene is disposed on the bottom of the polymer cushioning. The ratio of polyester to polypropylene in the nonwoven backing is between about 0.43 and about 2.3.
