Abstract (en)
[origin: DE19938809A1] A composite non-woven is made by first preparing (1,2,3,4) a carrier layer and consolidating it with water jets (6). A layer of micro-fibers obtained by melt-blowing (7) is then deposited on it before the absorbent layer of cellulose fibers, e.g. woodpulp fibers, is air-laid (8) on it. A covering layer can be added, the structure again consolidated by water jets and then dried.
