Overprint of solvent on total solvent coating

Claim 1

The method of forming an embossed pattern effect on pile fabric material which consists of the steps of: a. first providing a carpet material with a backing and a pile upper face surface, the pile face surface containing fibers which may be shrunk by a selected solvent while the backing material will be unaffected by the solvent solution, b. applying a first solvent solution to the total fiber face surface of the carpet to saturate the full length of the fibers with solvent solution, said solvent solution applied being of a concentration that can cause shrinkage of the pile face surface fibers, c. subsequently applying to only selected areas of the fiber face in a desired pattern a second solution which will dilute the total originally applied solvent-containing solution in the pattern areas to the point that the solvent now in the total solution will have little or no effect upon the fibers of the pile surface to shrink the fibers, and d. thereafter subjecting the pile fabric to heat to cause the yarns in the fiber face surface which have been only wetted by the first solvent-containing solution to shrink and present a desired embossed pattern appearance since in those areas where there has been the printing of the second solution, the solvent concentration has been diluted to the point that the solvent has very little or no shrinkage effect upon the fibers of the pile surface and, therefore, a two-level pile surface results.
