Absorbent cleaning pad having durable cleaning surface and method of making same

Abstract

A method for forming a cleaning pad body comprising a matrix web formed from binder fibers and a cleaning surface is provided. The method includes depositing a first concentration by weight of binder fibers so as to define the cleaning surface. A second concentration by weight of binder fibers is deposited onto the first concentration by weight of binder fibers, wherein the second concentration by weight of binder fibers is less than the first concentration by weight of binder fibers. The first and second concentrations by weight of binder fibers are bound together to form the matrix web.

         4 . The method of  claim 1 , wherein said first concentration by weight of binder fibers is at least about 50 percent greater than said second concentration by weight of binder fibers.  
     
     
         5 . The method of  claim 1 , wherein said first concentration by weight of binder fibers is at least about 100 percent greater than said second concentration by weight of binder fibers.  
     
     
         6 . The method of  claim 1 , further comprising the step of depositing a third concentration by weight of binder fibers so as to define a second cleaning surface, wherein the third concentration by weight of binder fibers is greater than the second concentration by weight of binder fibers.  
     
     
         7 . In a cleaning pad comprising a matrix web formed from binder fibers and a cleaning surface, a method of forming the cleaning pad comprising the steps of: 
 depositing a first portion of substrate comprising binder fibers so as to define the cleaning surface;    densifying the first portion of substrate;    depositing a second portion of substrate comprising binder fibers onto the first portion of substrate; and    bonding the first and second portions of substrate to form the matrix web.    
     
     
         8 . The method of  claim 7 , wherein said second depositing step further comprises depositing superabsorbent polymer particles onto the first portion of substrate.  
     
     
         9 . The method of  claim 7 , wherein a concentration by weight of binder fibers in the first portion of substrate is greater than a concentration by weight of binder fibers in the second portion of substrate.  
     
     
         10 . The method of  claim 7 , wherein a concentration by weight of binder fibers in the first portion of substrate is substantially the same as a concentration by weight of binder fibers in the second portion of substrate.  
     
     
         11 . In a cleaning pad comprising a matrix web formed from binder fibers and a cleaning surface, a method of forming the cleaning pad comprising the steps of: 
 depositing a first portion of substrate comprising binder fibers so as to define the cleaning surface;    depositing a second portion of substrate comprising binder fibers and non-binder fibers onto the first portion of substrate, wherein the second portion of substrate comprises a concentration by weight of non-binder fibers greater than a concentration of any non-binder fibers in the first portion of substrate; and    bonding the first and second portions of substrate to form the matrix web.    
     
     
         12 . The method of  claim 11 , wherein said first depositing step comprises depositing a mixture of non-binder fibers and binder fibers.  
     
     
         13 . The method of  claim 12 , wherein said first depositing step comprises depositing a mixture of cellulosic fibers and binder fibers.  
     
     
         14 . The method of  claim 11 , wherein said second depositing step comprises depositing binder fibers and cellulosic fibers.  
     
     
         15 . The method of  claim 11 , further comprising the step of depositing superabsorbent polymer particles.  
     
     
         16 . The method of  claim 11 , further comprising the step of densifying the matrix web.
