Abstract

There is provided a fibrous web which includes a binder and which is compressed to a density of up to about 0.3 g/cc. The web may preferably be formed by the bonded carded web process or air lay process. The binder may depend on hydrogen bonding using moisture or may be a non-aqueous solution, a powder, a fibrous binder or a conjugate fiber binder including a moisture triggerable component. Conjugate fibers may be crimped. When wetted the web of this invention should expand rapidly to greater than 80% of its uncompressed thickness and greater than 90% of its thickness when saturated if starting from the uncompressed state.
