摘要:
A three-dimensional film for use as an acquisition distribution layer in an absorbent article comprising a first surface with drains extending downward from the first surface, the drains being capable of transmitting fluid by gravity; and protrusions extending upward from the first surface to an upper surface with at least one capillary extending downward from the upper surface, the capillaries being capable of transmitting fluid in contact with the upper surface by capillary action. The drains rapidly transmit fluid through the film, particularly fluid that is dynamically-deposited. The capillaries transmit statically-retained fluid that is in contact with the upper surface of the protrusions.

Embodiments of a thin web comprising a plurality of channels extending through the film are disclosed. The channels are in a substantially closed position but are capable of being in an open position to allow flow from the female side through the film to the male side. In certain applications, a greater pressure on the female side than the male side is capable of opening the channels. Embodiments may also include a thin web comprising a plurality of three dimensional apertures extending through the plastic film. The apertures may form a substantially closed channel defined by a sidewall and the channels being disposed at an angle greater than 70° with respect to a female side of the film. The thin web may be a plastic film or a thermoplastic film comprising a polyolefin, for example, or any other suitable material. The polyolefin may comprise at least one of polyethylene, polypropylene, low density polyethylene, or high density polyethylene, for example.

Composite fabrics comprise a nonwoven web, preferably a fully calendared nonwoven web of fusible fibers, and a monolithic breathable polymer layer on at least one surface of the web and have excellent breathability, good abrasion resistance, and offer protection against both blood and viral agents.
摘要:
A composite particularly suited for use as a transfer layer in an absorbent article has a first layer comprising a formed film having a plurality of capillary-sized apertured protuberances and a plurality of two-dimensional drains, and a second layer in intimate contact with an apertured end of said capillary-sized protuberances and spaced from the first layer in a z-direction, the second layer is either a three-dimensional apertured formed film or a nonwoven web. In embodiments where the second layer is a three-dimensional formed film, the film contains a plurality of capillary sized protuberances that are of smaller diameter compared to the protuberances in the first layer and optionally also contains a plurality of drains, which can be either two-dimensional or three-dimensional, or combinations thereof.
摘要:
A system and method for determining the environmental impact of a process is disclosed in which resources are categorized into distinct Environmental Performance Indicators (“EPI's”), some of which are value EPIs that are derived based on the amount of the resource used per Finished Product Volume (FPV), which is representative of the amount of product that is produced by the process; and others are percentage EPIs that represent a measure of efficiency, and are derived from the amount of renewable resources used as a percentage of total resources used. A graphical representation of the EPIs allows a quick visual interpretation of the environmental friendliness of a particular process or group of processes, and allows a visual comparison between two different processes.

摘要:
A method for manufacturing composite webs and composite webs made thereby in which the web includes a perforated thermoplastic film and one or more nonwoven webs. The method provides a perforated thermoplastic film, a creped nonwoven web, the webs are fed in a face to face relationship to be bonded. The perforated thermoplastic film and the creped nonwoven web are bonded in a face to face relationship at a plurality of points of contact such that the creped structure of the nonwoven web is maintained and the composite web has a nonwoven face and a film face. The composite webs are extensible at least in the direction of the creping.
