Absorbent article featuring an endothermic temperature change member
View Patent ↗Disclosed is an absorbent article including a temperature change member for providing a cooling effect. The temperature change member includes a matrix of fibers and temperature change material intermixed within the matrix of fibers. The temperature change material includes erythritol.
1. An absorbent article comprising:
a liquid impermeable outercover;
an absorbent body disposed on said outercover; and
an endothermic temperature change material disposed within the absorbent body, the temperature change material including erythritol and xylitol in the form of particles;
wherein the temperature change material can provide the absorbent article with a temperature change of at least 5 degrees C., as determined by the temperature change test described herein.
2. The absorbent article of claim 1 including a temperature change member disposed with said absorbent body, said temperature change member comprising a temperature change composite comprising a matrix of fibers and the temperature change material intermixed within said matrix of fibers.
3. The absorbent article of claim 2 wherein the temperature change member can provide the absorbent article with a temperature change of at least 10 degrees C., as determined by the temperature change test described herein.
4. The absorbent article of claim 2 wherein the matrix of fibers comprises adhesive fibers.
5. The absorbent article of claim 4 wherein the adhesive fibers are provided by a hot melt adhesive.
6. The absorbent article of claim 2 wherein the matrix of fibers comprises absorbent fibers.
7. The absorbent article of claim 6 wherein the matrix of fibers further comprises binder material.
8. The absorbent article of claim 2 wherein the matrix of fibers is provided by a coform composite comprising polymer fibers and absorbent fibers.
9. The absorbent article of claim 8 wherein the polymer fibers are meltblown polymer fibers.
10. The absorbent article of claim 9 wherein the polymer fibers are stretch polymer fibers.
11. The absorbent article of claim 1 wherein the temperature change material comprises about 2 grams to about 6 grams of the erythritol.
12. The absorbent article of claim 1 wherein said temperature change material is in the form of particles, and comprises, by weight, about 40 percent to about 80 percent xylitol.
13. The absorbent article of claim 1 wherein said temperature change material is in the form of particles, and comprises, by weight, about 10 percent to about 50 percent xylitol.
