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 disposed on a carrier sheet. The discrete tufts have bond lines external to the tufts. The bond lines interrupt the Z-direction thickness of the tufts, to provide channels for improved collection and retention of debris from a target surface.
Claims4
A cleaning article bounded by edges defining an XY plane and a Z-direction perpendicular thereto, said 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 slits, wherein said slits extend from one said primary bond to an adjacent said primary bond, and
- at least one 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 two adjacent pluralities of tow fibers that are not joined to said carrier by the same primary bond.
