Abstract
Abstract A tufted carpet material is printed with a decorative pattern. The ink formulation used for printing contains a solvent for the fiber of the carpet. After printing, the carpet is steamed. This causes the fibers to shrink and/or partially dissolve to produce an embossed effect. The carpet is then washed and dried. There is produced a carpet having an embossed design with a natural fibrous appearance.

A carpet structure having a surface layer which is formed of loops of tufted carpet material which are formed from a continuous strand of material, said continuous strand of material being formed from a plurality of individual fibers, said strand of material being adaptable for tufting through a carpet backing structure, said individual loops being subjected to a solvent treatment operation which applies solvent to fibers of the individual tufts, said fiber also being subjected to a subsequent steaming operation, said solvent and steaming operation forming the top portions of the individual tufts into a fibrous-appearing mass which has the individual fibers within the mass adhered to each other so that the strand of fabric when stretched out in a generally straight line configuration will have a series of bumps thereon which are formed by the masses of sOlvent-treated fibers of the loops adhered to each other and being incapable of assuming a straight line configuration.
