Abstract
A fibrous structure comprising a cationic silicone polymer comprising one or more polysiloxane units and one or more non-pendant quaternary nitrogen moieties, and a method for making such a fibrous structure is provided. Further, a sanitary tissue product comprising the fibrous structure is also provided.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A fibrous structure comprising:
a. a fiber furnish layer; and b. a cationic silicone polymer layer discrete from the fiber furnish layer, wherein the cationic silicone polymer comprises one or more polysiloxane units and one or more non-pendant quaternary nitrogen moieties.
2 . The fibrous structure according to claim 1 wherein the cationic silicone polymer comprises at least 2 or more polysiloxane units and at least 2 or more quaternary nitrogen moieties.
3 . A single- or multi-ply sanitary tissue product selected from the group consisting of facial tissue products, hankies, toilet tissue products, paper towel products and mixtures thereof, comprising a fibrous structure according to claim 1 .
4 . A fibrous structure comprising:
a. a fiber furnish; and b. a cationic silicone polymer selected from the group consisting of:
i. a cationic silicone polymer comprising one or more polysiloxane units, one or more non-pendant quaternary nitrogen moieties and one or more alkylene oxide units;
ii. a cationic silicone polymer comprising one or more polysiloxane units, one or more non-pendant quaternary nitrogen moieties and one or more ring-opened epoxide units;
iii. a cationic silicone polymer comprising alternating units of: a) a polysiloxane comprising one or more polysiloxane units and one or more non-pendant quaternary nitrogen moieties; and b) a quaternary nitrogen-containing divalent organic moiety; and
iv. mixtures thereof.
5 . A single- or multi-ply sanitary tissue product selected from the group consisting of facial tissue products, hankies, toilet tissue products, paper towel products and mixtures thereof, comprising a fibrous structure according to claim 4 .
6 . A process for making a fibrous structure comprising the steps of:
a. providing a fibrous furnish; b. depositing the fibrous furnish on a foraminous forming surface to form an embryonic fibrous web; c. drying the embryonic fibrous web such that the fibrous structure is formed; and d. applying a cationic silicone polymer comprising one or more polysiloxane units and one or more non-pendant quaternary nitrogen moieties to the fibrous furnish and/or the embryonic fibrous web and/or the fibrous structure.
7 . The process according to claim 6 wherein the process further comprises the step of converting the. fibrous structure into a one-ply and/or multi-ply sanitary tissue product.
8 . The process according to claim 7 wherein the step of applying the cationic silicone polymer to the fibrous structure occurs before and/or concurrently with and/or after the step of converting.
9 . A fibrous structure made by the process according to claim 6 .
10 . A single- or multi-ply sanitary tissue product selected from the group consisting of facial tissue products, hankies, toilet tissue products, paper towel products and mixtures thereof, comprising a fibrous structure according to claim 9.Join the waitlist — get patent alerts
