Abstract

Fibrous structures comprising a fiber flexibilizing agent system, methods for making such fibrous structures and sanitary tissue products comprising such fibrous structures are provided.

Claims (11)

1. A fibrous structure comprising a fiber and a fiber flexibilizing agent system comprising a fiber flexibilizing agent wherein the increase in opacity of the fibrous structure resulting from the fiber flexibilizing agent system is greater than the net increase in opacity of the fibrous structure resulting from individual components of the fiber flexibilizing agent system.
2. The fibrous structure according to Claim 1 wherein the fiber comprises a cellulosic fiber.
3. The fibrous structure according to Claim 1 wherein the fiber flexibilizing agent is selected from the group consisting of humectants and plasticizers.
4. The fibrous structure according to Claim 3 wherein the plasticizer comprises a polyhydroxy compound; preferably a polyethylene glycol; more preferably a polyethylene glycol having a weight average molecular weight of from 100 to 500 g/mol.
5. The fibrous structure according to Claim 1 wherein the fiber flexibilizing agent system further comprises an opacity increasing agent; preferably selected from the group consisting of:
particulates, pigments, fillers and mixtures thereof; more preferably selected from the group consisting of: clay, calcium carbonate, titanium dioxide, talc, aluminum silicate, calcium silicate, alumina trihydrate, activated carbon, pearl starch, calcium sulfate, glass microspheres, diatomaceous earth, and mixtures thereof.
6. The fibrous structure according to Claim 1 wherein the increase in opacity of the fibrous structure resulting from the fiber flexibilizing agent system is 0.05% points greater than the net increase in opacity of the fibrous structure resulting from individual components of the fiber flexibilizing agent system.
7. The fibrous structure according to Claim 5 wherein the fiber flexibilizing agent and the opacity increasing agent are present in the fiber flexibilizing agent system at a weight ratio of from 2:1 to 100:1.
8. The fibrous structure according to Claim 1 wherein the fiber flexibilizing agent is present in the fibrous structure at from 2% to 30% by weight of the fibrous structure.
9. The fibrous structure according to Claim 5 wherein the opacity increasing agent is present in the fibrous structure at from 0.02% to 15% by weight of the fibrous structure.
10. A single-ply or multi-ply sanitary tissue product comprising a fibrous structure according to any of the preceding claims.
11. A method for making a fibrous structure according to any of claims 1-9, wherein the method comprises the steps of:
a) providing a fibrous structure;
b) contacting the fibrous structure with a fiber flexibilizing agent system comprising a fiber flexibilizing agent such that the change in opacity of the fibrous structure resulting from the fiber flexibilizing system is greater than the net change in opacity of the fibrous structure resulting from individual components of the fiber flexibilizing agent system.
