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 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, and
- a plurality of discrete 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 tow thickness in the z-direction,
- a plurality of elongate secondary bond disposed on at least one plurality of tow fibers and having a secondary bond thickness in the Z-direction, said secondary bond thickness being less than said tow thickness in the Z-direction, said secondary bond bridging at least some of said tow fibers, and
- a plurality of elongate slits through said carrier sheet and said tow fibers, said slits being disposed between a said primary bond and a said secondary bond.
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, and
- 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, said secondary bond thickness being less than said tuft thickness, each said secondary bond bridging at least two adjacent tufts of tow fibers, and
- a first plurality of elongate slits through said carrier sheet and said tow fibers, said first plurality of slits being spaced a first distance from a transversely adjacent secondary bond, and a second plurality of elongate slits through said carrier sheet and said tow fibers, said second plurality of slits being spaced a second distance from a transversely adjacent secondary bond, said second distance being greater than said first distance.
