ABSTRACT:
A fiber entanglement is provided which is characterized in that it is a three-dimensional entanglement comprising elastic fibers (A) each being a fine-denier fiber bundle or exhibiting porous fiber structure as seen on a fiber cross section with a number of irregularly-shaped pores extending in the fiber axis direction; nonshrinkable, nonelastic fibers (B); and shrinkable, nonelastic fibers (C); said fibers (A) are at least partially bonded or fused together at various points of contact with one another and, thereby, produce a taut condition; said nonshrinkable, nonelastic fibers (B) are folded several times over by means of the elastic fibers (A) and the shrinkable, nonelastic fibers (C). This fiber entanglement is useful as a base material for leather-like sheet materials.
