Patent Images
1. A method for delivering one or more active agents, the method comprising the steps:
- a. providing a nonwoven web comprising a plurality of filaments, wherein at least one of the filaments comprises one or more filament-forming materials and one or more active agents that are releasable from the filament when the filament is exposed to conditions of intended use, wherein the total level of the one or more filament-forming materials present in the filament is 50% or less by weight on a dry filament basis and the total level of the one or more active agents present in the filament is 50% or greater by weight on a dry filament basis; and
b. triggering the release of one or more of the active agents from the filament.

-
a. providing a nonwoven web comprising a plurality of filaments, wherein at least one of the filaments comprises one or more filament-forming materials and one or more active agents that are releasable from the filament as the filament'"'"'s morphology changes, wherein the total level of the one or more filament-forming materials present in the filament is less than 65% by weight on a dry filament basis and the total level of the one or more active agents present in the filament is greater than 35% by weight on a dry filament basis; and b. triggering the release of one or more of the active agents from the filament. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method for delivering one or more active agents, the method comprising the steps:
-
a. providing a nonwoven web comprising a plurality of filaments, wherein at least one of the filaments comprises one or more filament-forming materials and one or more ingestible active agents that are releasable from the filament upon ingesting by an animal, wherein the total level of the one or more filament-forming materials present in the filament is less than 80% by weight on a dry filament basis and the total level of the one or more active agents present in the filament is greater than 20% by weight on a dry filament basis; and b. triggering the release of one or more of the ingestible active agents from the filament. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
