Abstract:
1. A method of making foaming porous pads suitable for coupling to a hand-held device and for application to human skin, said method comprising: a. forming a nonwoven pile fabric by needlepunching individual fibers to form a backing layer comprising a substantially integrated, planar web of fibers primarily oriented in the plane of the web and needlepunching the substantially integrated, planar web of fibers to form a pile comprising individual pile fibers extending outwardly and away from the backing layer, wherein the fibers of the backing layer remain primarily oriented in the plane of the web, and the pile fibers extend outwardly and away from the plane of the web and end in at least one of free ends or loops spaced away from the backing layer; wherein at least about 90% of said pile fibers have a denier of less than about 9; b. applying a foaming composition to the nonwoven pile fabric; c. punching out individual porous pad substrates from the nonwoven pile fabric to form individual foaming porous pads; and d. packaging a plurality of individual foaming porous pads.
