Abstract
The invention provides a dry, disposable, polymeric product having sustained-release anti-microbial activity, the product consisting essentially of a polymeric material selected from the group consisting of fibers, fabrics, sheets, films and other stable woven, non-woven and knitted materials prepared from natural, man-made and synthetic polymers and an amine salt anti-microbial agent, the anti-microbial agent being incorporated in the polymeric material without an intermediary adhesive, carrier or linking agent and being releasable therefrom in anti-microbially effective amounts for a period of at least three days upon the product being brought into contact with a moist surface.
Claims14
A dry, disposable polymeric anti-microbial-applying product having sustained-release anti-microbial activity, said product consisting essentially of:
- a polymeric material selected from the group consisting of natural polymers, man-made-polymers and mixtures thereof in the form of fibers, yarns, woven, non-woven and knitted fabrics, sheets and films;
- and
- a water soluble amine salt anti-microbial agent, wherein
- said anti-microbial agent is releasably impregnated into said polymer material, coated on said polymeric material or a combination thereof without an intermediary adhesive or linking agent, and
- said anti-microbial agent is releasable from said polymeric material in anti-microbially effective amounts for a period of at least three days upon said anti-microbial product being brought into contact with a moist surface.

- a polymeric material selected from the group consisting of natural polymers, man-made-polymers and mixtures thereof in the form of fibers, yarns, woven, non-woven and knitted fabrics, sheets and films;
- and
- a water-soluble amine salt anti-microbial agent, wherein
- said anti-microbial agent is releasably impregnated into said polymeric material, coated on said polymeric material or a combination thereof without an intermediary adhesive or linking agent, and whereby contact of said polymeric anti-microbial-applying product with a moist surface causes said polymeric material to release said anti-microbial agent in anti-microbially effective amounts for a period of at least three days.
