摘要:
An absorbent article is disclosed for absorbing liquids, including body fluids such as menstrual discharges or urine. The absorbent article has a liquid impermeable backsheet on which is disposed an absorbent core, and first and second liquid permeable topsheet layers. The edge of the absorbent core defines a perimeter, and the first and second topsheet layers and the backsheet each extend laterally beyond the perimeter to define a continuous border segment surrounding the absorbent core. A liquid impermeable seal is formed in the border segment which surrounds the perimeter for preventing lateral migration of liquid from the absorbent core beyond the seal. The seal is formed to extend from an outer surface of the first topsheet layer to an outer surface of the backsheet, for establishing a capillary gradient in the second topsheet layer, thereby inhibiting wicking of fluid therethrough.

Apparatuses and processes for aperturing and stretching a web are disclosed. In one embodiment, the method involves feeding a web into a nip that is formed between at least one pair of intermeshing rolls. The first roll is a raised ridge rotary knife aperturing roll and the second roll is a ring roll; both rolls comprise ridges and grooves. The first roll comprises a plurality of spaced-apart teeth extending outwardly from the top surface of the ridges, said teeth having tips, wherein the top surface of said ridges are disposed between the tips of said teeth and the bottom surface of said grooves. These apparatuses and processes enable a web to be formed which comprises apertures having greater open area than previously achievable with traditional processes and apparatuses.

摘要:
A process for making an embossed web. A precursor web is provided between a forming structure and a static pressure plenum. The forming structure has a plurality of discrete protruded elements. Pressure is provided by the static pressure plenum against the precursor web and the forming structure to conform the precursor web to the discrete protruded elements of the forming structure to form the embossed web. The resulting embossed web has a plurality of discrete extended elements having open proximal ends.

An improved sanitary napkin is disclosed. The sanitary napkin has a laterally extensible flap which extends outwardly from one of the longitudinal edges of the sanitary napkin or a laterally extensible backsheet. The backsheet or flap may be laterally extended from the neutral, retracted position and will return to the retracted position upon release of the disturbing force. This arrangement provides the advantage that any adhesive strips or patches associated with the flaps or backsheet more easily move with the undergarment of the wearer and are less likely to be stressed or become detached from the undergarment of the wearer due to the forces encountered during typical wearer movements.
