Activated composite web for absorptive devices
An activated composite web includes a nonwoven layer, and a formed film layer attached to the nonwoven layer. The formed film layer includes a plurality of first apertured protuberances having a mesh count of at least 35, and a plurality of second apertured protuberances. Each of the second apertured protuberances has a cross-sectional area larger than each of the first apertured protuberances. A plurality of first lanes are aligned in a first direction and have a first width extending in a second direction substantially perpendicular to the first direction. The first apertured protuberances are located in the first lanes. A plurality of second lanes are aligned in the first direction and have a second width, less than the first width, extending in the second direction. The first lanes and the second lanes alternate with each other in the second direction. The second apertured protuberances are located in the second lanes.
ULTRA-THIN, FLEXIBLE THIN-FILM FILTERS WITH SPATIALLY OR TEMPORALLY VARYING OPTICAL PROPERTIES AND METHODS OF MAKING THE SAME
A method of making an optical filter film with varying optical properties includes the step of drawing a multilayer polymeric preform into an optical filter and varying at least one environmental condition being a member of the group including of heat, pressure, tension, and a drawing speed, the at least one environmental condition being varied over time or over a distance, or both, and causing a variation in layer thickness within the optical filter. The preform may be drawn through a furnace subjecting the preform to a heating power that varies across a width of the furnace or over time or both across the width and over time. The preform may also be drawn through the furnace while the drawing speed varies across a width of the furnace or over time or both across the width and over time.
Method and apparatus for making an apertured web
A method of creating a topsheet for an absorbent article is disclosed. The method includes the steps of: obtaining a pre-cursor web of material, the pre-cursor web of material having a first surface and an opposing second surface, wherein the pre-cursor web of material is a composite or laminate web having a first layer and a second layer, wherein the first layer is a film and the second layer is a nonwoven material having a plurality of fibers; forming a first plurality of apertures having sidewalls extending in a first direction from the pre-cursor web of material; forming a second plurality of apertures having sidewalls extending in a second direction from the pre-cursor material, wherein the first direction and the second direction are different; and forming a plurality of embossments in the pre-cursor web of material, wherein the embossments are oriented in a third direction opposite the first direction.

Ribbed film structures with pigment created visual characteristics
In one example embodiment, a film includes a coextruded structure having both an extruded ribbed skin layer that includes a plurality of ribs, and a core layer. The ribs are spaced apart by a web that is integral with the ribs. The film also includes a coloring agent that is substantially more apparent in the ribs than in the web, such that a contrast in color and/or color intensity between the ribs and the web is visible.
