Problems solved by technology

The structure described in this patent shows that this material is used very inefficiently in the waist region of the article because the absorbent capacity of the crotch region is actually higher than that of either waist region
Although US-A-4994037 states that superabsorbent materials do absorb some liquid, it is not recognized that the liquid absorbed away from the load zone is still substantially reduced
Additionally, the patent describes the use of fluff components especially around the load zone, which would necessarily result in a high rewet tendency of the article

Embodiment 1

[0184] Example 1 is an absorbent article comprising an absorbent core of the present invention, schematically shown in Figure 7, showing a garment side view of such an absorbent core, and Figure 8, a cross-sectional view of such an absorbent core. The acquisition layer 701 of Example 1 comprises a layer of chemically stiffened cellulose fibers and bicomponent fibers in a corresponding ratio of 87% to 13%. The acquisition layer 701 of Example 1 has a longitudinal dimension of 260 mm and a transverse dimension of 60 mm. The basis weight of the acquisition layer 701 is 340 gsm, resulting in a total weight of about 5.3 grams. The acquisition layer 701 is the layer positioned closest to the wearer facing surface.

[0185] Embodiment 1 further includes a front storage component 704 disposed in the front waist region 706 and a rear storage component 708 disposed in the rear waist region 707 . In Example 1, the storage components 704 and 708 are located on the surface of the absorbe...

Embodiment 2

[0188] Example 2 is an absorbent article comprising an absorbent core of the present invention, also schematically shown in Figure 7, showing a garment side view of such an absorbent core, and Figure 8, a cross-sectional view of such an absorbent core. The acquisition layer 701 of Example 2 comprises a layer of chemically stiffened cellulosic fibers and bicomponent fibers combined in a corresponding ratio of 87% to 13%. The acquisition layer 701 of Example 2 has a longitudinal dimension of 260 mm and a transverse dimension of 60 mm. The basis weight of the acquisition layer 701 is 340 gsm resulting in a total weight of about 5.3 grams. The acquisition layer 701 is the layer positioned closest to the wearer facing surface.

[0189] Embodiment 2 further includes a front storage component 704 disposed in the front waist region 706 and a rear storage component 708 disposed in the rear waist region 707 . In Example 2, the storage components 704 and 708 are located on the surface ...

Abstract

An absorbent article having an absorbent capacity in the crotch region that is lower than the absorbent capacity in the waist region when a load is placed vertically, wherein the actual wetted crotch thickness, as determined by the Curved Surface Acquisition Test, is less than the saturated crotch thickness, and may be less than Actual wet girdle thickness. In addition, the article should have good rewet properties.

Description

[0001] This application is a divisional application of the application dated April 23, 1999, application number 99807341.5, and titled "Absorbent article with improved fit when wet". technical field [0002] The present invention relates to absorbent structures for use in absorbent articles such as diapers, incontinent briefs, training pants, diaper supports and liners, hygiene garments and the like. More particularly, the present invention relates to absorbent structures which provide articles with improved fit and comfort when dry and especially when wetted by bodily fluids. Background technique [0003] Infants and other incontinent persons wear absorbent articles such as diapers to absorb and retain urine and other body exudates. Absorbent articles function to both contain exudates and to isolate these materials from the body of the wearer, the wearer's clothing and bedding. Disposable absorbent articles are known in the art in many different basic designs. For example...
