Patent ID: 7712178

Claim:
A cleaning tool sheet comprising: at least one fiber bundle bonded to one side of a base sheet, and a holding sheet bonded to a side of the base sheet opposite the fiber bundle to provide a space for receiving a holding member, wherein a central part in the direction of flow of the fibers constituting the fiber bundle is joined by a central joining part continuously formed in a central part of the base sheet, and the base sheet and the fiber bundle are joined at a plurality of spot-form joining parts formed intermittently along a spot-form line in a direction crossing the flow direction of the fibers between the central joining part and two end edges parallel therewith so that a first portion of fibers in the fiber bundle is bonded only by the central joining part and a second portion of fibers in the fiber bundle is bonded by the spot-form joining parts and by the central joining part, and wherein the spot-form line is positioned along a respective edge of the space provided by the holding sheet for receiving a holding member, and wherein the first and second portions of the fiber bundle which extend from the central joining part and the spot-form joining parts are liberated from the base sheet, and the fiber bundle comprises movable fibers having respectively different lengths between distal ends and fixed ends formed respectively by the central joining part and the spot-form joining parts.
