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.
A surge material for personal care products comprising from about 20 to about 60 weight percent cellulosic fibers, from about 40 to about 80 weight percent resilient fibers compressed with a binder which releases in the presence of moisture to a density of up to about 0.3 g/cc, and having a high capillary force, wherein said material expands upon being wetted to greater than 80% of its uncompressed thickness, decreasing its density and generating void volume to provide retention capacity.
A surge material for personal care products comprising fibers compressed with up to about 10 weight percent of a binder which releases in the presence of moisture selected from the group consisting of non-aqueous liquids, powders and fibers, to a density of up to about 0.3 g/cc, and having a high capillary force, wherein said material expands upon being wetted to greater than 80% of its uncompressed thickness, decreasing its density and generating void volume to provide retention capacity.
