Vinyl plastisols are fused to heat-sensitive primary backings and facing yarns integral therewith and expanded thereon by the application of a heating medium in the form of high velocity steam or a high velocity gas. Although the temperature of the heating medium is above the softening point of the heat-sensitive primary backing, the velocity of the heating medium and the angle at which it is directed against the plastisol-coated, heat-sensitive primary backing results in fusion and expansion of the vinyl plastisol on the heat-sensitive primary backing without damage to the backing material or facing materials associated therewith.
