Abstract
A non-irritating multi-ply absorbent article made by treating an inner surface with one or more antimicrobial agents and treating the one or more outer surfaces with one or more siloxane compositions, and methods of making and using the same. The antimicrobial agent will remain confined to the inner portion of the absorbent article, thereby preventing irritation to the user, and the siloxane treated ply(s) will provide a pleasing, soothing, non-irritating tactile quality. In one embodiment, the siloxane composition comprises an amine-modified polysiloxane, in which case the product will also entrap any absorbed fluid, holding it in contact with the antimicrobial agent, and preventing it from wetting through the product and contacting the user.
Claims34
A non-irritating, anti-microbial, multi-ply absorbent article comprising:
- a plurality of plies, at least one of said plies defining an outer ply;
- at least one of said plies having a surface defining an inner surface;
- at least one siloxane composition applied to at least a portion of said at least one outer ply;
- and
- an antimicrobially effective amount of at least one antimicrobial agent applied to said at least one inner surface.
An absorbent article comprising:
- a first outer ply, an inner ply, and a second outer ply;
- at least one siloxane composition applied to an outward surface of said first and second outer plies;
- and
- an antimicrobially effective amount of at least one antimicrobial agent applied to said inner ply.
A method for inhibiting the transfer of illness comprising:
- providing a multi-ply absorbent article comprising a plurality of plies, at least one of said plies defining an outer ply;
- at least one of said plies having a surface defining an inner surface;
- at least one siloxane composition applied to at least a portion of said at least one outer ply;
- and an antimicrobially effective amount of at least one antimicrobial agent applied to said at least one inner surface;
- contacting a fluid containing microbes with said absorbent article;
- absorbing said fluid within said absorbent article;
- and
- entrapping said fluid in contact with said antimicrobial agent within said absorbent article.
A method for making an antimicrobial, multi-ply absorbent article comprising:
- applying an antimicrobially effective amount of at least one antimicrobial agent to at least one surface of a first tissue paper web;
- applying an untreated tissue web to each surface of said first tissue paper web;
- crimping said tissue paper webs together to form a three ply composite;
- and
- applying at least one siloxane composition to at least one outer surface of said composite.
A method for making an anti-microbial, multi-ply absorbent article comprising:
- applying an antimicrobially effective amount of at least one antimicrobial agent to at least one surface of an absorbent material;
- applying a liquid-impermeable base to one surface of said absorbent material;
- applying a liquid-permeable outer ply to an opposite surface of said absorbent material;
- assembling said absorbent material, said base, and said outer ply to form a three ply composite;
- and
- applying at least one siloxane composition to at least one surface of said outer ply.
