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 low enough level to produce little or no shrinkage by itself upon subsequent application of heat. Portions of the fabric before heating are treated with a solution to increase the solvent concentration on the pile fabric to a point where the solvent will have a shrinking effect on the fabric. The subsequently heated product then has an embossed effect.
