Abstract
There is disclosed a structured fiber material with a three-dimensional network structure containing non-elastic crimped short fibers (A) and three-dimensionally crimped composite fibers (B), the fibers (B) being partially interlocked with each other, in which contact portions the fibers (B) are partially heat-bonded with each other; the fibers (B) being partially wound around the fibers (A) at their contact points, in which contact portions the fibers (A) and (B) are partially heat-bonded with each other; and the material having an apparent density of 0.005 to 0.10 g/cm.sup.3. Also disclosed is a process for producing the structured fiber material.
