Abstract
Abstract In a process for compressing sheet-like textile structures in the longitudinal and transverse direction, highly shrinking and normal shrinking polyester yarns of the same chemical composition are processed to give a sheet-like structure. The sheet-like structure is subjected to thermal treatment at 60 to 200 DEG C without stress and exhibits a fabric shrinkage of at least 15%. The process is used for the production of woven, knitted and tufted materials and for the compression of pile materials.
