A fiber entanglement is provided which is characterized in that it is a three-dimensional entanglement integratedly composed of elastic fibers (A) each being a fine-denier fiber bundle or having a porous fiber structure as seen on a fiber cross section with a number of irregular-shaped pores extending in the fiber axis direction, nonshrinkable, nonelastic fibers (B) and shrinkable, nonelastic fibers (C), that the fibers A are at least partly bonded or fused together at points of contact with one another and bring about a taut condition, that the nonshrinkable, nonelastic fibers B are folded several times over by means of the elastic fibers A and shrinkable, nonelastic fibers C. This fiber entanglement is useful as a base material for leather-like sheet materials. |
