Abstract
The present invention relates to a cleaning laminate comprising two functionally diverse surfaces, wherein said first surface is formed from an abrasive nonwoven fabric layer, which facilitates the process of loosening particulates, such as dust and dirt, and said second surface is formed from an air permeable, absorbent nonwoven fabric layer, which exhibits a lower coefficient of friction as compared to the abrasive side. The abrasive nonwoven fabric layer is selected from such materials that provide a coarse quality, as perceived as a resistance to deflection.
Claims1
A nonwoven cleaning laminate, comprising:
- a. an abrasive nonwoven fabric layer;
- b. an absorbent nonwoven fabric layer, wherein said absorbent nonwoven fabric layer exhibits a difference in coefficient of friction of at least 10% as compared to the abrasive layer;
- c. wherein said abrasive nonwoven fabric layer and said absorbent nonwoven fabric layer are joined together in a face to face juxtaposition so as to exhibit regions in the laminate that are bonded and un-bonded;
- and
- d. wherein said un-bonded regions have an abrasive nonwoven fabric layer to absorbent nonwoven fabric layer contact surface area of between about 0.5 square inches and 12 square inches.
