Abstract:
A wiper for disinfecting hard surfaces comprising:a fibrous laminate layer, said fibrous laminate layer being capable of absorbing a liquid when contacted therewith; a fibrous substrate layer having fibers therein with individually exposed surfaces thereon, said fibrous substrate layer being adhered to said fibrous laminate layer; and an anti-microbial agent distributed within the fibrous substrate layer and adhered to the individually exposed surfaces of the fibers in the fibrous substrate layer, said anti-microbial agent being capable of activation when contacted with a liquid, said activation including the release of a portion of said anti-microbial agent into said liquid that is contained within the wiper such that an anti-microbial solution forms therefrom, the anti-microbial agent being adapted to provide that the rate of said release is sufficient to ensure that an anti-microbial solution is formed in the liquid within the wiper after said wiper has been subjected to at least five rinsing; and said wiper being able to withstand at least 10 rinse cycles without substantially losing its ability to cause the liquid within the wiper after a rinse cycle to become an anti-microbial solution.
