ABSTRACT:
The invention relates to an improved method of making bulky non-woven fibrous material including cellulosic fibres and potentially crimped synthetic fibres, the improvement consisting of draining a layer of a foamed aqueous suspension of the fibres, drying the drained layer, and releasing the potential crimp in the synthetic fibres while supporting the layer substantially free from restraint against shrinkage.
