Fiber fleeces made of synthetic fibers or of natural fibers are compacted after their formation, for example, by carding or by simply being laid down in endless fiber fleeces. In the fleece according to the invention, which is intended to be voluminous yet compact, neither low-melting binding fibers nor chemical binders are used for the purpose. The mechanical needling method, i.e. with needles, cannot be used, however, because the volume is reduced too sharply. The desired volume is retained and the double fleece desired for hygienic products, for example, is achieved by the fleece produced, for example, on a card machine or aerodynamically initially being laid down on a previously compacted fleece, such as spun fleece made of endless fibers for example, as the carrier fleece and then being compacted in a continuous processing method by water needling at a water pressure of at least 100 bars and, preferably 180 bars, and thus being simultaneously joined to the carrier fleece.
