Abstract (en)

[origin: DE19620503A1] The manufacture of non-woven fabrics from a polyvinyl alcohol (PVA) fibre is known. The particular advantage of said PVA fibre is the property thereof of being soluble in water. To bond the non-woven fabric, it is therefore needled mechanically. The invention relates to a process which also uses hydrodynamic needling. Particular parameters for further treatment during water needling, and during subsequent drying characterise the supplementary features of the invention.
