Abstract

A method for producing a composite multi-layered absorbent article. At least two of the layers include a colored region.

First claim

What is claimed is:

1. A method of producing a multi-layered absorbent article, the method comprising the steps of:
a. providing an absorbent article converting line;
b. supplying a first precursor material to the converting line;
c. printing a first composition to the first precursor material;
d. supplying a second precursor material to the converting line;
e. producing a composite substrate from the first and second precursor materials;
f. supplying a lower substrate to the converting line;
g. printing a second composition to the lower substrate;
h. combining the composite substrate with the lower substrate to produce a laminate web; and
i. cutting the laminate web into individual absorbent articles, wherein the method of printing of the first composition and the second composition is via contact printing or non-contact printing, and wherein the method of printing of the first composition is different than the method of printing of the second composition.

2. The method of claim 1 , wherein the first precursor web is a polymer film.

3. The method of claim 1 , wherein the second precursor web comprises fibers.

4. The method of claim 3 , wherein the second precursor web is an airlaid cellulosic mat.

5. The method of claim 1 , wherein the first composition forms a first colored region and the second composition forms a second colored region, wherein the first colored region is disposed longitudinally outboard of the second colored region.

6. The method of claim 1 , wherein the first precursor material comprises a continuous web of material.

7. The method of claim 1 , wherein the second precursor material comprises a continuous web of material.

8. The method of claim 1 , wherein the lower substrate comprises a continuous web of material.

9. The method of claim 1 , wherein the lower substrate comprises a plurality of discrete pieces of material.

10. The method of claim 1 , wherein the first composition is printed to a surface of the first precursor web that faces the lower substrate.

11. The method of claim 1 , wherein the second composition forms a second colored region, and wherein the second composition is printed to a surface of the lower substrate that faces the composite substrate.

12. The method of claim 10 , wherein the second composition forms a second colored region, and wherein the second composition is printed to a surface of the lower substrate that faces the composite substrate.

13. The method of claim 9 , wherein the first colored region and the second colored region do not overlap with one another.

14. The method of claim 1 , wherein the absorbent article is at least one of facial tissue, toilet tissue, paper towels, cleaning wipes, cleaning pads, sanitary napkins, pantiliners, tampons, interlabial devices, infant diapers, children's training pants, adult incontinence products, or absorbent wipes.

15. The method of claim 2 , wherein the polymeric film comprises apertures.

16. The method of claim 1 , wherein the laminate web forms a portion of a feminine sanitary napkin, wherein the first precursor web forms a portion of a topsheet and wherein the lower substrate forms a portion of a secondary topsheet.

17. The method of claim 1 , further comprising the step of severing the lower substrate into individual sheets and placing the individual sheets onto the composite web.

18. The method of claim 17 , further comprising the step of providing an absorbent core web and cutting the absorbent core web into individual absorbent cores, and placing the individual absorbent cores onto the individual sheets of lower substrate.

19. The method of claim 18 , further comprising the step of placing a backsheet web over the individual absorbent cores to form a sandwich type web, bonding the sandwich type web, and cutting the sandwich type web.

20. The method of claim 2 , wherein the polymer film is a hydroformed film.
