Abstract
An improvement in the embossing of a thermoplastic textile, in particular the topsheet of an absorbent structure such as a diaper, which improves the high load caliper of the textile. The knobs and depressions of the mated embossing rolls used to emboss the textile have side walls which define a small angle with respect to a radius of the embossing roll. The preferred embossing knobs and depressions each define a frustum with a rhombic base and land, with the longer diagonal of the rhombus aligned in the machine direction of the embossing roll. The resulting embossed textile has stronger bosses, and thus maintains a greater caliper under load, than is observed in the prior art embossed textile.
