Method of Cleaning Using An Anti-Microbial Nonwoven Wipe

Abstract

The present invention is directed to a method of cleaning a hard surface with a nonwoven anti-microbial hard surface wipe, and more specifically to an anti-microbial hard surface wipe that more readily releases a disinfectant or anti-microbial agent, that includes coating a nonwoven wipe having a fibrous nonwoven substrate with a non-ionic and cationic binder mixture to provide a first coated nonwoven wipe, coating the first coated nonwoven wipe with a cationic dual quaternary ammonia anti-microbial agent to provide a second coated nonwoven wipe, providing a water source, and introducing the second coated nonwoven wipe to the water source wherein the cationic dual quaternary ammonia anti-microbial agent is readily released upon the second coated nonwoven wipe being introduced to the water source.

1 . A method of cleaning a hard surface, comprising the steps of:
 coating a nonwoven wipe comprising a fibrous nonwoven substrate with a non-ionic binder and cationic binder mixture to provide a first coated nonwoven wipe;   coating the first coated nonwoven wipe with a cationic dual quaternary ammonia anti-microbial agent to provide a second coated nonwoven wipe;   providing a water source; and   introducing said second coated nonwoven wipe to said water source wherein said cationic dual quaternary ammonia anti-microbial agent being readily released into said water source.   
     
     
         2 . The method of  claim 1 , wherein said non-ionic binder exhibits a low affinity for said dual quaternary ammonia anti-microbial agent. 
     
     
         3 . The method of  claim 1 , wherein said fibrous nonwoven substrate comprises natural fibers. 
     
     
         4 . The method of  claim 1 , wherein said fibrous nonwoven substrate comprises natural fibers selected from the group consisting of cotton, wood pulp and viscose rayon. 
     
     
         5 . The method of  claim 1 , wherein said fibrous nonwoven substrate comprises carded and cross-lapped staple length fibers. 
     
     
         6 . The method of  claim 1 , wherein the fibrous nonwoven substrate comprises a three-dimensionally imaged fibrous nonwoven substrate. 
     
     
         7 . The method of  claim 6 , wherein the nonwoven wipe further comprises a scrim layer reducing the extensibility of said three-dimensionally imaged fibrous nonwoven substrate. 
     
     
         8 . The method of  claim 6 , wherein said scrim layer is selected from a unidirectional filament scrim, a bi-directional filament scrim, an expanded film, and a thermoplastic spunbond. 
     
     
         9 . The method of  claim 1 , wherein the nonwoven wipe comprises an additional layer selected from the group consisting of a fabric layer and a film layer. 
     
     
         10 . The method of  claim 9 , wherein said additional layer is a film layer selected from the group consisting of a cast film, an extruded film, and a reticulated film. 
     
     
         11 . The method of  claim 1 , further comprising cleaning a hard surface with said wipe after said introducing of said second coated nonwoven wipe to said water source.
