ABSTRACT:
A pile fabric is treated overall with a solution containing a solvent for the fiber comprising the pile fabric. The solvent concentration of the solution is of a sufficiently high level to induce shrinkage of the fiber upon subsequent application of heat. Portions of the fabric before heating are treated with a solution to dilute the solvent on the carpet to a point where it will have minimum or no effect on the fabric. The subsequently heated product then has an embossed effect.
