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.
Claims15
A cleaning article having a longitudinal axis and a transverse direction orthogonal thereto, said cleaning article comprising:
- at least one sheet,
- at least one layer of tow fibers joined to said sheet at a seal to form a laminate, said tow fibers generally extending in the transverse direction, and
- a repeating unit,
- said seal comprising a plurality of adjacent, successive discrete bonds collectively extending in a generally longitudinal direction to form a spine,
- said discrete bonds at least partially overlapping adjacent bonds in both the longitudinal direction and the transverse direction, so that each said tow fiber is joined to said sheet by at least one said discrete bond, wherein said bonds are spaced on a longitudinal pitch of 3 to 18 mm and said bonds are serpentine shaped, wherein each said bond of said seal has an identical longitudinal length and identical longitudinal pitch between adjacent bonds, said length being greater than said pitch, wherein each said bond has a width, said length being greater than said width, wherein a plurality of said bonds are substantially identical in size and shape, wherein a longitudinally orientated line through the repeating unit intercepts the discreet bonds the repeating unit in at least two positions.
A cleaning article having a longitudinal axis and a transverse direction orthogonal thereto, said cleaning article comprising:
- at least one sheet,
- at least one layer of tow fibers joined to said sheet at a seal to form a laminate, said tow fibers generally extending in the transverse direction, and
- a repeating unit,
- said seal comprising a plurality of discrete bonds collectively extending in a generally longitudinal direction,
- said discrete bonds overlapping in the longitudinal direction, whereby each said tow fiber is joined to said sheet by at least one said discrete bond, a plurality of said bonds having at least one segment oriented in the transverse direction, wherein said bonds are spaced on a longitudinal pitch of 3 to 18 mm and said bonds are serpentine shaped, wherein each said bond of said seal has an identical longitudinal length and identical longitudinal pitch between adjacent bonds, said length being greater than said pitch, wherein each said bond has a width, said length being greater than said width, wherein a plurality of said bonds are substantially identical in size and shape, wherein a longitudinally orientated line through the repeating unit intercepts the discreet bonds the repeating unit in at least two positions.
A cleaning article having a longitudinal axis and a transverse direction orthogonal thereto, said cleaning article comprising:
- at least one sheet,
- at least one layer of tow fibers joined to said sheet at a seal to form a laminate, said tow fibers generally extending in the transverse direction, and
- a repeating unit,
- said seal comprising a plurality of successive discrete bonds collectively extending in a generally longitudinal direction to form a spine, said seal comprising two generally longitudinal rows of discrete bonds, each said bond having a length and a width perpendicular thereto, said discrete bonds at least partially overlapping adjacent bonds in the longitudinal direction, so that each said tow fiber is joined to said sheet by at least one said discrete bond, wherein said bonds are spaced on a longitudinal pitch of 3 to 18 mm and said bonds are serpentine shaped, wherein each said bond of said seal has an identical longitudinal length and identical longitudinal pitch between adjacent bonds, said length being greater than said pitch, wherein each said bond has a width, said length being greater than said width, wherein a plurality of said bonds are substantially identical in size and shape, wherein a longitudinally orientated line through the repeating unit intercepts the discreet bonds the repeating unit in at least two positions.
