Abstract
A cleaning product comprises a base sheet and at least one layer of filaments or split yarns oriented in one direction, the base sheet and the layer are stacked and bonded together at a plurality of bonding lines extending in a direction intersecting with the one direction, and the base sheet is cut together with the layer intermittently in the intersecting direction between adjacent bonding lines to form cutting portions, thereby forming brushing portions with the layer. The cleaning product can be produced simply and conveniently at small cost. Further, it also has an excellent dust collecting effect.
