Cleaning Pad Having Preferred Performance With Water

Abstract

A cleaning pad for absorbing liquids from a hard, target surface. The cleaning pad has a hydrophobic floor sheet, and a core joined to the floor sheet. The core has absorbent gelling material therein with a gradient distribution, so that the pad has a particular minimum absorbency as used with water or with common amine oxide cleaning solution. A hydrophilic smoothing strip is joined to the outwardly facing surface of said floor sheet. The cleaning pad provides both good absorbency and a coefficient of friction falling within a specified range judged advantageous for cleaning. The absorbency and coefficient of friction work well with both water and an amine oxide cleaning solution.

What is claimed is: 
     
         1 . A cleaning pad comprising:
 a liquid pervious floor sheet, and   an absorbent core juxtaposed with said floor sheet and comprising absorbent gelling material therein, said cleaning pad having an absorbency with water of 0.48 to 1.   
     
     
         2 . A cleaning pad according to  claim 1  having an absorbency with water of 0.5 to 1. 
     
     
         3 . A cleaning pad according to  claim 2  having an absorbency with water of 0.55 to 0.9. 
     
     
         4 . A cleaning pad according to  claim 1  comprising from 5 to 50 w % AGM. 
     
     
         5 . A cleaning pad according to  claim 4  having a gradient distribution of AGM, with AGM percentage decreasing as the floor sheet is approached. 
     
     
         6 . A cleaning pad comprising:
 a liquid pervious floor sheet, and   an absorbent core juxtaposed with said floor sheet, said cleaning pad having a coefficient of friction with water of 0.6 to 0.9.   
     
     
         7 . A cleaning pad according to  claim 6  having a coefficient of friction with water of 0.65 to 0.8. 
     
     
         8 . A cleaning pad according to  claim 6  having a coefficient of friction with water of 0.7 to 0.8. 
     
     
         9 . A cleaning pad according to  claim 6  having an absorbency with water of 0.5 to 1. 
     
     
         10 . A cleaning pad according to  claim 9  having an absorbency with water of 0.55 to 0.7. 
     
     
         11 . A cleaning pad according to  claim 9  wherein said core comprises two layers disposed in fluid communication. 
     
     
         12 . A cleaning pad according to  claim 11  wherein said cleaning pad further comprises a liquid impervious backsheet, and core further comprises AGM, said AGM being disposed in a gradient distribution increasing in AGM percentage as said backsheet is approached, said core being disposed between said floor sheet and said backsheet. 
     
     
         13 . A cleaning pad according to  claim 12  wherein said floor sheet has an outwardly facing surface, said cleaning pad further comprising a smoothing strip joined to said outwardly facing surface of said floor sheet. 
     
     
         14 . A cleaning pad comprising:
 a liquid pervious floor sheet, and   an absorbent core juxtaposed with said floor sheet,   said cleaning pad having a coefficient of friction with water of 0.4 to 0.9 and an absorbency with water of 0.48 to 1.   
     
     
         15 . A cleaning pad according to  claim 14  wherein said absorbency with water is from 0.5 to 0.9. 
     
     
         16 . A cleaning pad according to  claim 15  having a coefficient of friction with water of 0.65 to 0.9. 
     
     
         17 . A cleaning pad according to  claim 16  wherein said absorbency with water is from 0.55 to 0.8. 
     
     
         18 . A cleaning pad according to  claim 17  having a coefficient of friction with water of 0.65 to 0.8. 
     
     
         19 . A cleaning pad according to  claim 14  wherein said liquid pervious floor sheet is hydrophobic. 
     
     
         20 . A cleaning pad according to  claim 19  wherein said liquid pervious floor sheet has an outwardly facing surface, said cleaning pad further comprising a hydrophilic smoothing strip joined to said outwardly facing surface of said floor sheet.
