Abstract
Apertured fibrous structures and more particularly apertured fibrous structures containing one or more fibrous elements, for example filaments, containing one or more fibrous element-forming materials and one or more active agents that are releasable from the fibrous element when exposed to conditions of intended use, and methods for making same.
Claims27
A fibrous structure 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 exposed to conditions of intended use, the fibrous structure further comprises one or more apertures such that the fibrous structure exhibits two or more of the following properties:
- a. a Basis Weight Index Ratio of less than 1 as measured according to the Aperture Parameter Test Method;
- b. a Basis Weight Index Transition Ratio of greater than 1 as measured according to the Aperture Parameter Test Method;
- c. a Fiber Orientation Index Ratio of greater than 1 as measured according to the Aperture Parameter Test Method;
- d. an Average Aperture Equivalent Diameter of greater than 0.15 mm as measured according to the Aperture Parameter Test Method;
- e. an Average Fractional Open Area of from about 0.005% to about 80% as measured according to the Aperture Parameter Test Method;
- and
- f. an Average Aperture Area of greater than 0.02 mm2 as measured according to the Aperture Parameter Test Method.
