Abstract
A process for sculpturing a pile fabric, e.g., nylon pile fabric, is provided which comprises selectively contacting the pile surface of said fabric with a fiber degrading composition, said composition comprising a fiber degrading agent in a concentration sufficient to reduce the tensile strength of the fibers of the pile in the selected areas so that said pile fibers may be removed by mechanical action; said fiber degrading agent being an aromatic sulfonic acid having a pK value of from about 0.1 to about 2, and said fiber degrading composition further containing a diluent for said fiber degrading agent; heating said pile fabric to a temperature sufficient to cause the tensile strength of said fibers of said pile in the selected areas to be reduced sufficiently so that said fibers may be removed by mechanical means, but said temperature being low enough so as not to result in complete destruction of the fiber integrity prior to removal by mechanical means; and removing said degraded portion of said pile fibers by mechanical means to provide a sculptured pile fabric. Products made according to the process are also provided.
