Abstract
A cleaning article having a layer of tow fibers and a layer of sheet material, joined together in a laminated construction. The layer of tow fibers and the sheet may be joined together at a spine. The spine is a seal between the adjacent, superimposed layer(s) of fibers and sheet(s). The seal comprises a plurality of individual bonds. The bonds overlap in the longitudinal direction and optionally in the transverse direction. This arrangement provides, at least, the benefit of less instantaneous energy draw when forming the seal using thermal bonding.
