Abstract: Bonded nonwovens can be produced with particular advantage by the wet method by treating the textile fibers prior to the addition of the binder polymers with water-soluble cationic polycondensation products which have been prepared from carbamides, formaldehyde, dicyanodiamide and salts of ammonia or of amines.
