    Abstract: PURPOSE:To obtain a packed fiber durable to the use over a long period and produced by laminating thin webs composed mainly of short fibers, by specifying the repeated average compressibility to a specific level or above. CONSTITUTION:A packed fiber material 1 is produced by stacking a number of small-sized thin webs 2 each composed of a number of short fibers. The short fibers are randomly arranged in the plane of the thin web and arranged along the laminar direction of the thin web in the direction projected to the plane view or side view. The repeated average compressibility of the packed fiber material 1 is made to be >=85%.
