Abstract

The present disclosure relates to fibrous structures including active agents and having a graphic printed thereon. In some embodiments, a nonwoven web may include a fibrous structure comprising filaments. In turn, the filaments may include filament forming material, and an active agent releasable from the filaments when exposed to conditions of intended use. In addition, a graphic may be printed directly onto the fibrous structure.

Claims (51)

1. A product comprising

a water-soluble fibrous structure comprising a plurality of inter-entangled filaments and void areas between each filament of the plurality of inter-entangled filaments; wherein at least one of the inter-entangled filaments comprises a filament forming material; and

one or more discrete, water-insoluble, active agent-containing particles present within the product and releasable from the product when exposed to conditions of intended use;

wherein the product further comprises a graphic printed directly on at least a portion of the plurality of inter-entangled filaments and/or void areas the fibrous structure, and

wherein the graphic is formed from an ink at least a portion of which non-uniformly penetrates the inter-entangled filaments and/or void areas on a surface of the water-soluble fibrous structure to a depth of 100 microns or less.

2. The product of claim 1 wherein the fibrous structure is formed as a pouch wall material that defines an internal volume of a pouch.

3. The product of claim 2 wherein the surface faces the internal volume of the pouch.

4. The product of claim 2 wherein the surface faces away from the internal volume of the pouch.

5. The product of claim 1 wherein the graphic includes a primary color selected from the group consisting of: cyan, yellow, magenta, and black.

6. The product of claim 5 wherein the primary color of cyan has an optical density of greater than about 0.05.

7. The product of claim 5 wherein the primary color of yellow has an optical density of greater than about 0.05.

8. The product of claim 5 wherein the primary color of magenta has an optical density of greater than about 0.05.

9. The product of claim 5 wherein the primary color of black has an optical density of greater than about 0.05.

10. The product of claim 1 wherein the fibrous structure exhibits one or more of the following properties:

a. a geometric mean tensile of at least about 200 g/M or greater;

b. a geometric mean peak elongation of at least about 10% or greater;

c. a geometric mean modulus of about 5000 g/cm or less;

d. an average disintegration time of about 60 seconds or less;

e. an average dissolution time of about 600 seconds or less;

f. an average disintegration time per gsm of sample of about 1.0 second/gsm or less;

g. an average dissolution time per gsm of sample of about 10 second/gsm or less;

h. a dry average ink adhesion rating of at least about 1.5 or greater; and

i. a wet average ink adhesion rating of at least about 1.5 or greater.

11. The product of claim 1 wherein the fibrous structure has one or more of the following properties:

a. a dry average ink adhesion rating of at least about 1.5 or greater; and

b. a wet average ink adhesion rating of at least about 1.5 or greater.

12. The product of claim 1 wherein the graphic comprises L*a*b* color values, the graphic being defined by the difference in CIELab coordinate values disposed inside the boundary described by the following system of equations:

{ a*=− 13.0 to −10.0; b*= 7.6 to 15.5 }→b*= 2.645 a*+ 41.869

{ a*=− 10.0 to −2.1; b*= 15.5 to 27.0 }→b*= 1.456 a*+ 30.028

{ a*=− 2.1 to 4.8; b*= 27.0 to 24.9 }→b*=− 0.306 a*+ 26.363

{ a*= 4.8 to 20.9; b*= 24.9 to 15.2 }→>b*=− 0.601 a*+ 27.791

{ a*= 20.9 to 23.4; b*= 15.2 to −4.0 }→b*=− 7.901 a*+ 180.504

{ a*= 23.4 to 20.3; b*=− 4.0 to −10.3 }→b*= 2.049 a *−51.823

{ a*= 20.3 to 6.6; b*=− 10.3 to −19.3 }→b*= 0.657 a *−23.639

{ a*= 6.6 to −5.1; b*=− 19.3 to −18.0 }→b*=− 0.110 a *−18.575

{ a*=− 5.1 to −9.2; b*=− 18.0 to −7.1 }→b*=− 2.648 a *−31.419

{ a*=− 9.2 to −13.0; b*=− 7.1 to 7.6 }→b*=− 3.873 a *−42.667; and

wherein L* is from 0 to 100.

13. The product of claim 1 wherein the fibrous structure has a geometric mean tensile of at least about 200 g/M or greater.

14. The product of claim 1 wherein the fibrous structure has a geometric mean peak elongation of at least about 10% or greater.

15. The product of claim 1 wherein the fibrous structure has a geometric mean modulus of about 5000 g/cm or less.

16. The product of claim 1 wherein the fibrous structure has an average disintegration time of about 60 seconds or less.

17. The product of claim 1 wherein the fibrous structure has an average dissolution time of about 600 seconds or less.

18. The product of claim 1 wherein the fibrous structure has an average disintegration time per gsm of sample of about 1.0 second/gsm or less.

19. The product of claim 1 wherein the fibrous structure has an average dissolution time per gsm of sample of about 10 second/gsm or less.

20. The product of claim 1 wherein the product is a layered product comprising two or more layers selected from the group consisting of: layers of a plurality of inter-entangled filaments, layers of particles, layers of a mixture of a plurality of inter-entangled filaments and particles, and combinations thereof.
