Abstract

An apparatus and process for forming an absorbent web ( ) includes an airlaying of a first fibrous stratum ( ), and an airlaying of an intermediate fibrous stratum ( ) onto the first fibrous stratum. A liquid, wet-strength agent is distributed onto fibers of the intermediate fibrous stratum, and at least a second fibrous stratum ( ) is airlaid onto the intermediate fibrous stratum ( ). The method is desirably configured to operatively form or join the intermediate fibrous stratum ( ) with the first and second fibrous strata, and render the intermediate fibrous stratum ( ) substantially non-dispersible in an aqueous liquid. In a particular aspect, the strata of the web ( ) can be operatively compressed prior to curing the wet-strength agent. In another aspect, the liquid wet-strength agent can be distributed onto the fibers of the intermediate fibrous stratum ( ) during an airlaying of the intermediate fibrous stratum.
