摘要： A pressure cell for subjecting a liquid-absorbent article to static compression; employed for conducting liquid-absorbency test procedures. The pressure cell includes an inflatable bag which compresses the absorbent article while conforming to its tri-dimensional configuration in order to achieve a uniform pressure distribution. The pressure cell is particularly suitable for conducting tests on non-planar, anatomically shaped absorbent articles or test samples that undergo a change in volume upon wetting. The invention also extends to a method for conditioning a liquid-absorbent article by the application of pressure during experimental liquid-absorbency procedures.

摘要： A composite absorbent structure capable of extremely short fluid penetration time, well-suited for use as an absorbent core in disposable absorbent products such as adult disposable briefs, diapers, incontinence pads, sanitary napkins, wound dressings and bandages. The composite absorbent structure comprises a highly absorbent fluid transfer sheet having a low fluid retentiveness, and a laminated, wicking reservoir with a high fluid retentiveness in intimate fluid communication with the fluid transfer sheet to draw fluid therefrom under the effect of capillary action. The laminated reservoir includes superposed layers, the layer closest to the fluid transfer sheet being provided with a fluid distribution well. A highly porous and hydrophilic spacer element is inserted between the reservoir layers establishing a high void volume area which forms an extension of the fluid absorptive well between the reservoir layers. The invention also comprehends a method for providing a rapid fluid absorption in a disposable absorbent product.

摘要： This invention relates to a novel absorbent structure and absorbent products containing this absorbent structure. More particularly, the absorbent structure of this invention contains a high-loft, bulky, low-density cover layer, a higher density transfer layer, a very high density, retentive reservoir layer and an impermeable barrier layer. The cover and barrier layers are sealed around their periphery and, preferably, all the layers are bonded to each other to form a unitized structure.

摘要： A method and apparatus for measuring the capillary attraction developed at a surface of an absorbent body intended to be used in a sanitary article such as a sanitary napkin, a diaper, a urinary pad, an adult brief, a tampon or a wound dressing, among others. The apparatus comprises a probe of fritted glass providing an array of capillary passageways in fluid communication with the interior of a closed cell completely filled with liquid. A pressure sensor mounted to the closed cell observes the liquid pressure therein. When the probe is placed in contact with the absorbent body, the capillary attraction exerted on liquid in the probe capillaries by the porous network of the absorbent body is transmitted through the liquid medium in the cell to the pressure sensor. The pressure data thus obtained reflects the state of dryness of the absorbent body surface. The capillary attraction measurement is made with no appreciable transfer of liquid toward the absorbent body to avoid altering its condition.
