Foaming porous pad for use with a motorized device
View Patent ↗A foaming porous pad suitable for coupling to a hand-held device and for application to human skin includes a porous pad substrate and a foaming composition disposed on the porous pad substrate. The porous pad substrate includes a nonwoven pile fabric having a nonwoven backing layer and a pile comprising individual fibers extending from the backing layer. The nonwoven pile fabric has fibers having a denier of less than about 9. Other aspects of the disclosure include a kit including a foaming porous pad and a motorized handheld device, methods of making the foaming porous pad, and methods of using the foaming porous pad.
1. A foaming porous pad suitable for coupling to a hand-held device and for application to human skin, the pad comprising:
a. about 50 to about 25 wt-% of a porous pad substrate comprising a nonwoven pile fabric comprising a blend of fibers having a denier between 1.5 and 10, at least about 50% of the fibers having a length to diameter ratio of greater than about 300:1 and wherein the nonwoven pile fabric comprises:
i. a nonwoven backing layer having a first nonwoven surface and a second surface, said first nonwoven surface configured as a contacting surface for attachment to the hand-held device; and
ii. a pile formed from said nonwoven backing layer and extending from said backing layer second surface, and consisting essentially of individual fibers selected from the group consisting of polyesters, polyolefins, and combinations thereof and, each of said individual fibers being spaced from one another and individually extending from said nonwoven backing layer second surface and including pile fibers with free ends spaced apart from one another; and
b. about 50 to about 75 wt-% of a foaming composition disposed on the porous pad substrate;
wherein said backing layer is processed to form said pile therefrom to include said pile fibers with free ends spaced apart from one another.
2. The foaming porous pad of claim 1 , wherein said nonwoven pile fabric comprises at least about 90 wt-% of fibers having a denier of up to about 6.
3. The foaming porous pad of claim 2 , wherein said nonwoven pile fabric comprises a blend of fibers, and wherein about 90 to about 50 wt-% of said fibers have a first denier of up to about 3 and about 10 to about 50 wt-% of said fibers have a second denier, greater than the first denier and up to about 6.
4. The foaming porous pad of claim 1 , wherein said foaming porous pad comprises at least about 50 wt-% of said foaming composition.
5. The foaming porous pad of claim 1 , wherein said foaming porous pad comprises between about 60 and about 70 wt-% of said foaming composition.
6. The foaming porous pad of claim 1 , wherein said nonwoven pile fabric comprises fibers having a denier of less than about 9.
7. The foaming porous pad of claim 1 , wherein said nonwoven backing layer first surface comprises fibers for engagement by an attachment surface of the hand-held device.
8. The foaming porous pad of claim 1 , wherein said nonwoven backing layer comprises two layers of nonwoven material.
9. The foaming porous pad of claim 1 , wherein said backing layer has a higher density than said pile.
