Abstract: The felting material, consisting of natural and/or synthetic fibres, is subjected to a point compression by steel lips in a V formation to allow hot fluid polymerisates to be passed into the material. This is allowed to reassert itself for coling to stabilise the polymerisate layer inside. Strength and stability is given to the felt, esp. for carpeting applications, without wastage.

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.
