Abstract (en)

[origin: DE19909835A1] Tissue sheet (I) comprises at least 2 layers of (A) a support layer containing a wet strength agent and (B) an absorbent layer having a different fiber composition. A tissue sheet (I) comprises at least 2 layers of (A) a support layer containing a wet strength agent and (B) an absorbent layer having a different fiber composition. Layer (B) predominantly comprises a special fibrous material whereby the absorption characteristics of (B) are not influenced by the presence of a wet strength agent and /or the wet strength agent contained within layer (A). Independent claims are included for (i) a process for the preparation of (I) by preparation of layers (A) and (B) separately; bonding the at least 2 layers together while they are still damp to form a multi-layer sheet followed by drying.
