Abstract: The disclosed cleaning article includes a working surface made from first ends of a plurality of channels and a capturing surface. The channels are formed from multiple strands of a skip-slit sheet, which in an initial state extend in a first direction and together define a plane. The multiple strands are attached to each other at bridging regions. At least some of the strands are spread from the initial state and separated from each other between the bridging regions to provide the plurality of channels, and at least some of the strands that are separated from each other are twisted out of the plane. A cleaning tool including the cleaning article, a method of making the cleaning tool, and a stack of skip-slit spunbond nonwoven sheets are also disclosed.
