Abstract

The present invention relates to a method of forming a molded fibrous product, comprising the steps of foaming an aqueous suspension of natural fibers, optionally in combination with synthetic fibers, to provide a first fibrous foam, a surfactant may be added to aid the foaming, feeding the fibrous foam into a mold, mechanically withdrawing a part of the water contained in the foam to produce a solidified, moist fibrous composition, and evaporating water from the solidified, moist fibrous composition to produce a dry fibrous product.
