Benefits of technology

This patent describes a nonwoven web that can be used as a topsheet of a disposable absorbent article, like a feminine hygiene article. The nonwoven web gives a soft feel to the user and also helps to blur or mask stains caused by menses or urine.

Problems solved by technology

If the topsheet does not successfully blur / mask the staining caused by menses / urine, the user may be left with the impression that the disposable absorbent article did not perform well.
However, films are generally not considered to be soft without additional processing.
Nonwoven topsheets can provide a soft feel to the user; however, nonwoven topsheets typically do not have good blurring / masking capability with regard to menses / urine stains.

[0180]FIG. 11 is an SEM photo of a polypropylene fiber with glycerol tristearate additive added to the fibers as a master batch (8 wt % Techmer PPM 17000 High Load Hydrophobic). The masterbatch comprised about 60 percent by weight polypropylene and about 40 percent by weight glycerol tristearate. As shown the fiber 1191 comprise a plurality of fibrils 1192 extending from the surface thereof.

[0181]FIG. 12 is an SEM photo of a bi-component fiber 1291 of polyethylene and polypropylene arranged in 30 / 70 sheath / core configuration—the polyethylene being the sheath. The additive (glycerol tristearate) was added to the fibers as a master batch (17% of Techmer PPM 17000 High Load Hydrophobic). The master batch comprised about 60 percent by weight polyethylene and about 40 percent by weight glycerol tristearate. The sheath of the fiber comprised 17 percent by weight master batch and 83 percent by weight polyethylene. As shown, the fiber 1291 comprises a plurality of fibrils 1292 extending the...

Abstract

Nonwoven webs for use in absorbent articles are disclosed. A nonwoven web can have a first nonwoven layer and a second nonwoven layer. The first nonwoven layer has a first plurality of fibers, a first side and a second side opposed to the first side, and a first plurality of apertures extending through the first nonwoven layer from the first side to the second side. The first nonwoven layer also has an additive which is disposed, at least in part, on at least a portion of the first plurality of fibers. The second nonwoven layer has a second plurality of fibers, a first side and a second side opposed to the first side. The second nonwoven layer is attached to the first nonwoven layer such that at least a portion of the second plurality of fibers is in liquid communication with the first plurality of apertures.

Description

FIELD OF THE INVENTION[0001]The disclosure herein relates generally to a nonwoven web and an article incorporating the nonwoven web.BACKGROUND OF THE INVENTION[0002]Topsheets of disposable absorbent articles perform a valuable function. Topsheets are typically the interface between the disposable absorbent article and the user. As such, topsheets should be tactilely appealing to the user. Additionally, particularly in the context of hygiene articles, topsheets should blur / mask staining caused by menses and / or urine. If the topsheet does not successfully blur / mask the staining caused by menses / urine, the user may be left with the impression that the disposable absorbent article did not perform well.[0003]There are a variety of topsheets known in the art. For example, in some conventional feminine hygiene articles, topsheets may comprise a film. Films are typically desirable because they provide good blurring / masking benefits regarding menses / urine staining. However, films are general...
