    摘要： The present invention provides a stable material having enhanced extensibility and a method for making the same. A tensioning force is applied to the neckable material to neck the material in a direction perpendicular to the first direction. The necked material is then subjected to mechanical stabilization to provide a stabilized extensible necked material. The stabilized extensible necked material is then passed between the peripheral surface of a cylinder which is driven in rotating motion and a device for pressing the stabilized extensible necked material against the peripheral surface of the cylinder. A retarding member retards the passage of the stabilized extensible necked material and directs the material away from the peripheral surface of the cylinder. The stabilized extensible necked material is easily extended in a direction parallel to the first direction and perpendicular to the first direction.

    摘要： The present invention pertains, in a preferred embodiment, to a method for selectively aperturing a nonwoven web exhibiting a plurality of surface energy gradients. The method includes the steps of: providing a nonwoven web of fibers exhibiting a surface energy, the nonwoven web having a first surface, a second surface and a plurality of fluid passageways placing the first and second surfaces in fluid communication with one another; applying a surface treatment to the first surface of the nonwoven web, the surface treatment having a surface energy less than the surface energy of the fibers of the nonwoven web creating a plurality of surface energy gradients defined by discontinuous, spaced regions which are adapted to exert a force on a fluid contacting the first surface, such that the fluid will be directed toward the fluid passageways for transportation away from the first surface and in the direction of the second surface; weakening the nonwoven web at a plurality of locations creating a plurality of weakened, melt-stabilized locations; and applying a tensioning force to the nonwoven web to cause the nonwoven web to rupture at the plurality of weakened, melt-stabilized locations creating a plurality of apertures in the nonwoven web coincident with the plurality of weakened, melt-stabilized locations. The web is particularly well suited for use as a topsheet on a disposable absorbent article.

    摘要： An extensible apertured nonwoven web, and a method for making such an apertured nonwoven web. In one embodiment the method comprises the steps of providing an apertured nonwoven web, incrementally stretching it in a direction substantially parallel to the cross machine direction, and applying tension in the machine direction such that the web width after applying tension is less than the web width after incremental stretching. In another embodiment the method comprises the steps of providing a nonwoven web; weakening the nonwoven web at a plurality of locations to create a plurality of weakened, melt-stabilized locations; applying a first tensioning force to the nonwoven web to cause the nonwoven web to rupture at the plurality of weakened, melt-stabilized locations creating a plurality of apertures in the nonwoven web coincident with the weakened, melt-stabilized locations, incrementally stretching the nonwoven web in a direction substantially parallel to the cross machine direction, and applying tension in the machine direction such that the web width after applying machine direction tension is less than the web width after incremental stretching. An apparatus for producing a web of the present invention by this method is also disclosed. The extensible apertured nonwoven web produced has a plurality of apertures each having a hole size greater than 2 mm2, and a hole aspect ratio less than 6, the nonwoven web having an open area greater than 15% and being capable of at least 70% extension in the cross machine direction at a loading of 10 g/cm.

    摘要： A pump dispenser for fluent products is disclosed as inluding a container for housing the fluent product, dispensing outlet means on the container, a follower piston closing the lower end of the container below the product, and means for varying the volume within such dispenser. The volume varying means comprises a plunger adapted to be reciprocated within the dispenser to alternately decrease the volume therewithin and, following such decrease, return to its original position thereby increasing the volume within the dispenser. The plunger further comprises a peripheral skirt having predetermined outer lateral dimensions at its lower distal end, and an enlarged attachment head on such lower distal end. The attachment head has predetermined outer lateral dimensions which are larger than the outer lateral dimensions of such lower distal end therey effectively forming a reentrant portion on the plunger above the enlarged head. A flexible thin-walled diaphragm adapted to isolate and seal the volume reducing means from the fluent product is connected about its outer periphery to the dispenser. The diaphragm further has a central portion substantially conforming to the enlarged attachment head and reentrant portion of the plunger thereby effectively locking the diaphragm to the plunger and its attachment head. The attached diaphragm is thereby adapted to provide a substantially frictionless seal between the reciprocable plunger and the fluent product. The unique structure and combination of the plunger and flexible diaphragm of the subject pump dispenser provides for ease of manufacturing and handling of such pump dispenser subassembly.
