ABSTRACT:
A rug or mat having a pattern in relief is formed by printing a pattern on a rug having face yarns of a thermoplastic fiber, and subsequently heating the printed rug. The ink is applied by silk-screen, stencil or the like to apply enough ink to raise the melting point of the thermoplastic yarns, so the printed portions do not shrink as much as the untreated, or unprinted, portion of the rug. A plastisol ink has been found to protect the printed yarns. Because an ink is used to protect the yarns, the pattern can be defined by yarn height and color.
