Abstract
A cleaning sheet is provided. The cleaning sheet includes a fabric layer with a plurality of cavities in at least one major surface. In one embodiment, fabric layer surface secured to a flexible backing layer so as to define an outer fabric surface with a plurality of cavities therein. The cavities can include a tacky bottom surface capable of enhancing the retention of dust and other particles. Cleaning implements and methods of cleaning surfaces using the cleaning sheet are also described.
Claims18
A cleaning sheet comprising:
- a nonwoven fiber aggregate layer secured to a flexible backing layer;
- adhesive disposed between the nonwoven fiber aggregate layer and the flexible backing layer;
- wherein the nonwoven fiber aggregate layer has a plurality of apertures therethrough, a basis weight of 30 to 100 g/m2 and a CD initial modulus of 20 to 800 m;
- and
- wherein the apertures expose at least a portion of the adhesive.
A cleaning sheet comprising:
- a nonwoven fiber aggregate layer secured to a flexible backing layer;
- wherein the cleaning sheet has a breaking strength of at least 500 g/30 mm and an elongation at a load of 500 g/30 mm of no more than 25%;
- and the nonwoven fiber aggregate layer has a plurality of apertures therethrough, a basis weight of 30 to 100 g/m2 and a CD initial modulus of 20 to 800 m;
- the apertures having an average cross-sectional dimension of 1 mm to 10 mm.
A cleaning implement comprising:
- a cleaning sheet which comprises a nonwoven fabric layer having a basis weight of from 30 to 100 g/m2 and a CD initial modulus of 20 to 800 m;
- said fabric layer being secured to a flexible backing layer by an adhesive disposed between said fabric layer and the flexible backing layer, and said fabric layer having a plurality of apertures therethrough,;
- wherein the apertures expose at least a portion of said adhesive, thereby forming an outer fabric surface with a plurality of cavities therein which include a tacky surface.
A cleaning utensil kit for cleaning surfaces comprising:
- a cleaning head;
- a cleaning sheet capable of being coupled to the cleaning head, the cleaning sheet comprising a nonwoven fiber aggregate layer secured to a flexible backing layer;
- wherein the cleaning sheet has a breaking strength of at least 500 g/30 mm and an elongation at a load of 500 g/30 mm of no more than 25%;
- and the nonwoven fiber aggregate layer has a plurality of apertures therethrough, a basis weight of 30 to 100 g/m2 and a CD initial modulus of 20 to 800 m, wherein the apertures have an average cross-sectional dimension of 1 mm to 10 mm.
