Abstract
A composite floor covering having an upper decorative layer, a stabilizing layer, and an optional cushioning layer is characterized in that the decorative layer itself comprises a fabric base and a plastic matrix having a transparent portion. The plastic matrix may include an opaque portion. At least the transparent portion of the plastic matrix has discrete fibrous structures embedded therein. The plastic matrix material is selected with melting and rheological characteristics such that the plastic matrix is prepared and applied to the fabric base in fluid form and solidifies under conditions at which the fabric base and embedded fibrous structures remain substantially intact. The fabric layer may be totally embedded within the plastic matrix or may form the lower surface of the plastic matrix. The decorative layer may include (i) fabric fragments, (ii) groupings of multi-oriented individual fibers, or (iii) mixtures of fragments and individual fibers. The fabric base may, if desired, have a decorative facing.
