Abstract (en)

[origin: EP0889151A1] A process for manufacturing fibrous structures comprising a wet laid fibre web comprising substantially water insoluble, substantially non water swellable particles that are added to the fibre web by distributing them onto a surface of the wet laid fibre web before the drying stage. A fibrous structure according to this method is also described. <IMAGE>
