Abstract

The present disclosure is generally directed to a dispersible moist wipe comprising hydroentangled fibers and a binder composition. The moist wipe demonstrates high initial wet strength while maintaining effective dispersion in an aqueous environment. The moist wipe has potential application as a flushable surface cleaning product and/or a flushable cleansing cloth.

First claim

What is claimed is:

1. A dispersible moist wipe comprising hydroentangled fibers and from about 0.5 grams per square meter (gsm) to about 5 gsm of an ion-triggerable binder composition, the wipe having a geometric mean tensile (GMT) wet strength of at least about 300 grams per inch (g/in), a GMT soak wet strength of less than about 180 g/in, and a CD stretch percent greater than about 40%.

2. The dispersible moist wipe as set forth in claim 1 wherein the GMT wet strength is at least about 500 g/in.

3. The dispersible moist wipe as set forth in claim 2 wherein the GMT wet strength is at least about 700 g/in.

4. The dispersible moist wipe as set forth in claim 2 wherein the GMT soak strength of the wipe is less than about 160 g/in.

5. The dispersible moist wipe as set forth in claim 2 wherein the GMT soak strength of the wipe is less than about 140 g/in.

6. The dispersible moist wipe as set forth in claim 2 wherein the CD stretch percent of the wipe is between about 45% and about 55%.

7. The dispersible moist wipe as set forth in claim 2 wherein the CD stretch percent of the wipe is between about 47% and about 49%.

8. The dispersible moist wipe as set forth in claim 2 wherein the wet density is in a range from about 0.100 g/ccm to about 0.115 g/ccm.

9. The dispersible moist wipe as set forth in claim 2 wherein the wet density is in a range from about 0.110 g/ccm to about 0.112 g/ccm.

10. The dispersible moist wipe as set forth in claim 1 , wherein the ion-triggerable binder composition is present in a range between about 1.2 gsm to about 2.6 gsm.

11. The dispersible moist wipe as set forth in claim 10 , wherein the ion-triggerable binder composition is present in a range between about 1.8 gsm to about 2.2 gsm.

12. The dispersible moist wipe as set forth in claim 1 , wherein the hydroentangled fibers comprise regenerated fibers and natural fibers.

13. The dispersible moist wipe as set forth in claim 12 , wherein the natural fibers have a fiber length between about 0.5 millimeter and about 1.5 millimeters.

14. The dispersible moist wipe as set forth in claim 12 , wherein the natural fibers have a length-weighted average fiber length greater than about 2 millimeters.

15. The dispersible moist wipe as set forth in claim 12 , wherein the regenerated fibers have a fiber length of from about 3 millimeters to about 60 millimeters.

16. The dispersible moist wipe as set forth in claim 12 , wherein the regenerated fibers have a fineness in the range of from about 0.5 denier to about 3 denier.
