Title: High capacity fluid absorbent members
Inventor: BUENGER DANIEL EDWARD
IPC: A61F13/53
Filed: 1997-04-04
Abstract: PURPOSE: Fluid absorbent members improve fluid acquisition, distribution, and storage properties and can be used in a variety of absorbent articles such as catamenial products, disposable diapers, adult incontinence pads and briefs, and the like. CONSTITUTION: Fluid absorbent members comprise three basic components:chemically stiffened, twisted, and curled bulking fibers, high surface area fibers, and chemical binder additive. Fluid absorbent members use a high surface fiber and refining to provide capillary pressure to the fluid absorbent member. These high surface area fibers are generally small and highly conformable. They provide the substrate with capillary pressure well in excess of the capillary pressure found in the bulk-providing chemically stiffened, twisted, and curled fibers alone. A presently preferred fiber for this high surface application is the eucalyptus family of wood pulp fibers. Eucalyptus provides desirable capillary pressure characteristics in combination with the chemically stiffened, twisted, and curled fibers and will not easily pass through a forming screen.

Abstract: PURPOSE: A vacuum processing chamber is provided which has improved serviceability, flexibility in choice of components and/or improvement in uniformity of gas flow especially at low pressures. CONSTITUTION: A chamber includes an opening in a sidewall thereof and the opening is large enough to allow the substrate support to be removed from the chamber through the opening. A modular mounting arrangement extends through the opening and removably supports the substrate support in the interior of the chamber at a position located inwardly of an inner sidewall of the chamber. The mounting arrangement includes a mounting flange and a support arm. The mounting flange is attached to an exterior surface of the chamber and the support arm extends between the substrate support and the mounting flange. The chamber includes a single vacuum port in a central portion of an endwall of the chamber spaced from the substrate support. The vacuum port is connected to a vacuum pump which removes gases from the interior of the chamber and maintains the chamber at a pressure below atmospheric pressure. The substrate support is easy to service or replace since it can be removed through a sidewall of the chamber. The sidewall mounted substrate support also allows a large vacuum port to be located in the endwall of the chamber thus allowing high flow to be achieved by connecting the vacuum port a large capacity vacuum pump. The chamber also includes a modular liner, a modular plasma generating source and a modular vacuum pumping arrangement, each of which can be replaced with interchangeable equipment.
