Abstract:
A flexible sheet for a disposable garment, said flexible sheet comprising an apertured web and a fibrous layer;said apertured web comprising a plastic web having longitudinal and transverse directions, being from about 0.001 to about 0.05 mm thick, and including a plurality of substantially flat portions, each being from about 0.03 to about 1 mm wide, imperforated, and extending in parallel one to another in said longitudinal direction, and a plurality of intermittent apertures extending in said longitudinal direction between said flat portions having upper and lower surfaces so as to form a plurality of aperture rows extending in parallel one to another in said longitudinal direction; pairs of said flat portions having said aperture rows therebetween being interconnected by a plurality of bridge portions which extend therebetween and across said aperture rows; said bridge portions extending across the respective aperture rows being formed intermittently in the transverse direction, providing two types of bridge portions: those which extend upward or downward from the upper surfaces of the flat portions to the upper surfaces of the respectively adjacent flat portions so as to describe arcs and those which are flush with the flat portions; said intermittent apertures being defined by edges of said flat portions which extend in said longitudinal direction and edges of said bridge portions which extend in said transverse direction;, said flat portions being provided at least along said edges thereof which extend in said longitudinal direction with a first set of substantially pointed tooth-shaped portions which extend upward from the upper surfaces of said flat portions; said fibrous layer being joined to the lower surfaces of said flat portions of said apertured web; and said fibrous layer comprising component fibers assembled together by mechanical intertwining, heat-sealing or adhesive bonding of the component fibers, wherein said fibrous layer contains at least one of thermoplastic synthetic fibers, chemical fibers and natural fibers, and at least part of said component fibers extend upwardly in said intermittent apertures of said apertured web.
