Abstract
A vinyl tension floor covering includes a reinforcing layer, preferably disposed below the neutral bending plane. The floor covering elongates in at least one direction due to a controlled pre-stressed condition and tends to return to its original pre-elongated dimension. Reinforcing layers expand in the across machine direction as well as machine direction in response to a tensile stretching force in the machine direction or roll-up growth.
