Cleaning pad having correlated cleaning performance
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.
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 absorbent gelling material being distributed in a gradient with a decreasing AGM percentage as said floor sheet is approached,
said cleaning pad satisfying the inequality:
absorbency with amine oxide cleaning solution=0.75*cof+/−0.1,
wherein 0.55<cof <0.75,
absorbency is between 0.50 and 0.6, and
cof is the coefficient of friction with amine oxide cleaning solution,
wherein said core comprises a single layer, wherein said gradient comprises stepwise increments.
