Abstract
A cleaning article defining an XY plane and a Z direction perpendicular to the plane. The cleaning article has discrete tufts of tow fibers bonded to a carrier sheet by primary bonds. The discrete tufts have secondary bond lines external to the tufts. The secondary bond lines interrupt the Z-direction thickness of the tufts, to provide channels for improved collection and retention of debris from a target surface. The tufts are created by slits between the primary bonds and secondary bonds, which yield plural tuft sizes. The slits may be transversely unequally spaced between adjacent bonds.

A cleaning article bounded by alternating longitudinal edges and transverse edges defining an XY plane and a Z-direction perpendicular thereto, a longitudinal axis defining a longitudinal direction and a transverse axis defining a transverse direction, said cleaning article comprising:
- a carrier sheet having a first side and a second side opposed thereto,
- a plurality of discrete spaced apart tufts of tow fibers joined to said first side of said carrier sheet by a plurality of primary bonds and extending outwardly therefrom in the Z-direction to have a tuft thickness in the Z-direction,
- a plurality of elongate secondary bonds having a secondary bond thickness in the Z-direction, said secondary bond thickness being less than said tuft thickness, each said secondary bond bridging at least two adjacent tufts of tow fibers,
- a plurality of elongate slits through said carrier sheet and said tow fibers, each said slit being unequally transversely spaced between one said primary bond and one said secondary bond adjacent thereto, and
- a channel on said carrier sheet between said tufts, said channel being free of said tufts, said channel being juxtaposed with said longitudinal axis.
