Abstract:
1. A fabric, comprising: mutually transverse thread systems, wherein at least one of said thread systems includes a differential shrinkage yarn C; said shrinkage yarn C comprising 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; said components A and B bound together by nodes formed by vortical turbulence; wherein in said fabric the number (y) of said nodes per meter in said yarn C is predetermined as a function of the yarn count (x) of the transverse thread system so that the number (y) of said nodes exceeds a minimum value and increases proportionally above said minimum value as a function of the yarn count (x); and wherein the number (y) of nodes per meter as a function of yarn count (x) is expressed as follows: wherein, relative to the finished fabric: the node number per meter in said yarn C is “y”, and the yarn count per centimeter is “x”.
