Claim 22:
23. A nonwoven web comprising one or more particulate active agents and a plurality of inter-entangled, polar solvent-soluble, non-thermoplastic filaments comprising one or more filament-forming materials comprising a polar solvent-soluble material comprising a hydroxyl polymer and one or more active agents included in the plurality of inter-entangled, polar solvent-soluble, non-thermoplastic filaments to produce an intended effect in an environment external to the plurality of inter-entangled, polar solvent-soluble, non-thermoplastic filaments and that releases from the plurality of inter-entangled, polar solvent-soluble, non-thermoplastic filaments when the plurality of inter-entangled, polar solvent-soluble, non-thermoplastic filaments morphology changes upon dissolution of the plurality of inter-entangled, polar solvent-soluble, non-thermoplastic filaments during use, wherein the total level of the filament-forming materials present in the plurality of inter-entangled, polar solvent-soluble, non-thermoplastic filaments is less than 65% by weight on a dry filament basis and the total level of the active agents present in the plurality of inter-entangled, polar solvent-soluble, non-thermoplastic filaments is greater than 35% by weight on a dry filament basis, wherein the at least one of the one or more active agents is selected from the group consisting of: surfactants, enzymes, perfumes and mixtures thereof, and wherein the one or more particulate active agents are separate from the plurality of inter-entangled, polar solvent-soluble, non-thermoplastic filaments.
