Abstract
An adherent article, such as a bandage or adhesive tape, having a nonwoven substrate that contains water soluble fibers is provided. The water soluble fibers of the nonwoven substrate can include polyvinyl alcohol fibers that only dissolve at temperatures greater than 37° C. and/or polyvinyl alcohol fibers that can dissolve at temperatures less than about 37° C. The adherent article also includes a pressure-sensitive adhesive applied to the nonwoven substrate that facilitates adherence of the substrate to human skin. The pressure-sensitive adhesive can be water soluble or generally insoluble, but dispersible in water.
Claims45
An adherent article comprising:
- a nonwoven substrate having a first and second side, said nonwoven substrate comprising fibers that are soluble in an aqueous solution selected from the group consisting of cold water soluble fibers, hot water soluble fibers, and combinations thereof, wherein said fibers soluble in said aqueous solution comprise greater than about 50% by weight of said nonwoven substrate;
- and
- an adhesive applied to at least a portion of said first side of said nonwoven substrate, said adhesive being capable of adhering said nonwoven substrate to human skin in the absence of said aqueous solution.
An adherent article comprising:
- a nonwoven substrate having a first and second side, said nonwoven substrate comprising polyvinyl alcohol fibers that are soluble in an aqueous solution selected from the group consisting of cold water soluble polyvinyl alcohol fibers, hot water soluble polyvinyl alcohol fibers, and combinations thereof, said polyvinyl alcohol fibers comprising greater than about 50% by weight of said nonwoven substrate;
- and
- a pressure-sensitive adhesive applied to at least a portion of said first side of said nonwoven substrate, said pressure-sensitive adhesive being capable of adhering said nonwoven substrate to human skin in the absence of said aqueous solution, said pressure-sensitive adhesive being either soluble in said aqueous solution or generally non-soluble, and dispersible in said aqueous solution.
A bandage comprising:
- a nonwoven substrate having a first and second side, said nonwoven substrate comprising polyvinyl alcohol fibers that are soluble in an aqueous solution selected from the group consisting of cold water soluble polyvinyl alcohol fibers, hot water soluble polyvinyl alcohol fibers, and combinations thereof, wherein said polyvinyl alcohol fibers comprise greater than about 50% by weight of said nonwoven substrate;
- and
- a pressure-sensitive adhesive applied to at least a portion of said first side of said nonwoven substrate, said pressure-sensitive adhesive being capable of adhering said nonwoven substrate to human skin in the absence of said aqueous solution, said pressure-sensitive adhesive being either soluble in said aqueous solution or generally non-soluble and dispersible in said aqueous solution;
- and
- an absorbent pad attached to said first side of said nonwoven substrate.
An adherent article comprising:
- a nonwoven substrate having a first and second side, said nonwoven substrate comprising cold water soluble fibers and hot water soluble fibers;
- and
- an adhesive applied to at least a portion of said first side of said nonwoven substrate, said adhesive being capable of adhering said nonwoven substrate to human skin in the absence of said aqueous solution.
An adherent article as defined in claim wherein said dispersible fibers comprises less than about 50% by weight of said nonwoven substrate.
An adherent article comprising:
- a nonwoven substrate having a first and second side, said nonwoven substrate comprising polyvinyl alcohol fibers that are soluble in an aqueous solution, said polyvinyl alcohol fibers comprising hot water soluble polyvinyl alcohol fibers and cold water soluble polyvinyl alcohol fibers, said polyvinyl alcohol fibers comprising greater than about 50% by weight of said nonwoven substrate;
- and
- a pressure-sensitive adhesive applied to at least a portion of said first side of said nonwoven substrate, said pressure-sensitive adhesive being capable of adhering said nonwoven substrate to human skin in the absence of said aqueous solution, said pressure-sensitive adhesive being either soluble in said aqueous solution or generally non-soluble and dispersible in said aqueous solution.
A bandage comprising:
- a nonwoven substrate having a first and second side, said nonwoven substrate comprising polyvinyl alcohol fibers that are soluble in an aqueous solution, said polyvinyl alcohol fibers comprising hot water soluble polyvinyl alcohol fibers and cold water soluble polyvinyl alcohol fibers;
- and
