Cleaning sheets with improved cleaning performance
The present invention is directed to a nonwoven cleaning sheet having a distance (d), defined as the expanse from the front, or leading edge of the cleaning sheet, to the back, or trailing edge of the sheet, that is imparted with two or more three-dimensional protrusions so as to create a tortuous particulate path(s) within the cleaning sheet that extends more than about 1.6 times the aforementioned distance (d), resulting in a cleaning sheet with an improved particulate entrapment and entrainment performance.
1 . A cleaning sheet comprising a leading edge, expansive cleaning or cleansing surface comprising three-dimensional protrusions and tortuous particulate paths, and a trailing edge, which defines the length of said cleaning sheet, wherein the shortest distance of said tortuous paths as it travels from said leading edge to said trailing edge while being further defined by said protrusions is about 1.6 times the length of said cleaning sheet.
2 . A cleaning sheet as in claim 1 , wherein said sheet comprises more than one layer.
3 . A cleaning sheet as in claim 1 , wherein said sheet comprises a cleaning or cleansing agent.
4 . A cleaning sheet as in claim 1 , wherein said sheet is a hard surface cleaning sheet.
5 . A cleaning sheet as in claim 1 , wherein said sheet is a hygienic cleaning sheet.
