ABSTRACT:
A fabric includes mutually transverse thread systems, with at least one of the thread systems including a differential shrinkage yarn C. The shrinkage yarn C has at least one effect component A that irreversibly elongates itself upon heat treatment, and at least one shrinkage component B that shortens itself upon heat treatment. The components A and B are bound together by nodes, wherein the number (y) of nodes per meter in the yarn C is predetermined as a function of the yarn count (x) of the transverse thread system so that the number (y) of nodes exceeds a minimum value and increases proportionally above the minimum value as a function of the yarn count (x).
