A disposable diaper product useful for collecting a urine sample from an infant is disclosed. In one example the product may have a liquid control structure overlying a liquid impermeable backsheet, with a plan surface area defining a volume coextensive therewith, wherein a portion of the volume defined by at least 50 percent of the plan surface area contains no more than 50 percent by weight absorbent material. In another example the product may have a liquid control structure overlying a liquid impermeable backsheet, and have an average Liquid Release Ratio of at least 3 percent. A method for collecting a urine sample from an infant is also disclosed, in which a diaper is used for collection.

An absorbent article includes an absorbent core sandwiched between a topsheet and a backsheet, the article being arranged along a longitudinal axis and a transversal axis extending in a perpendicular direction and the article defining a front portion, a back portion and a crotch portion, wherein the absorbent core includes an absorbent component enclosed by a core cover including an upper side and a lower side and the core is formed with a sealing arrangement for joining the upper and lower sides including two channel sealings extending along the longitudinal axis in said crotch portion and defining a first channel sealing width and a second channel sealing width, respectively. Furthermore, the absorbent article includes at least one wetness indicator having a longitudinal extension and being positioned generally only in the front portion, only in the back portion, or in both the front portion and the back portion.

An absorbent article has an absorbent body with a colored fiber layer colored in a different color from a color of any member other than the absorbent body across a whole in a front-back direction and a width direction thereof. The colored fiber layer is visually recognizable from an outside.

In an embodiment, a garment, such as a smart pull-up, includes at least one outer section and a midsection attached to the outer section. The midsection includes a first antimicrobial membrane patch layer configured to contact a wearer's body, a second antimicrobial membrane patch layer disposed adjacent to the first antimicrobial patch layer, and an air gap disposed between the first patch and second antimicrobial patch layers. The first and second antimicrobial patch layers each are formed from respective balanced warp big tows and fill tows in a plain-weave pattern, and each layer include copper filaments disposed in a plurality of the tows, each of the copper filaments including at least Cu+/Cu+++ ions. Such a smart pull-up may be suitable for either adult who cannot use the toilet, or child, or healthy adult and, therefore, may urinate and defecate himself/herself.

The present disclosure is directed, in part, to webs or topsheets for absorbent articles and methods of making the same. The webs and topsheets include bicomponent fibers having a first component and a second component, wherein the first component has a different hydrophilicity than the second component. The webs and topsheets include a continuous land area and discrete zones of modified surface energy. One of the first and second components forms an outer surface of the fibers in the continuous land area and the other of the components at least partially forms an outer surface of the fibers in the discrete zones of modified surface energy such that the discrete zones of modified surface energy have a different hydrophilicity than the continuous land area.

Described herein are apparatus and methods for detecting substances of abuse or other analytes in liquids. For example, the apparatus and methods described herein can be used for real-time detection of analytes, such as substances of abuse. The methods comprise providing a detection area comprising a chromatographic membrane capable of receiving the liquid and allowing for migration of the liquid, the chromatographic membrane comprising an anti-analyte antibody-particle conjugate, an analyte-conjugate protein at a test line; exposing at least the first location of the apparatus to the liquid; and determining whether an interaction between the analyte-conjugate protein and the liquid occurs to detect the presence of the analyte. The chromatographic membrane may further comprise an anti-species antibody at a control line. Specific buffers are disclosed, and these buffers may be used in the preparation of the apparatus to overcome challenges associated with miniaturization and challenges associated with exposure to beverages.

A sensor system for detecting a property of or within an absorbent article may comprise an absorbent article and a sensor. The absorbent article may comprise a garment-facing layer and an absorbent assembly. The sensor may be disposed in and/or on the absorbent article. The sensor may be separable from the absorbent article. The sensor may be configured to sense a change in condition within the absorbent article.

Described herein are a wearable apparatus and methods for detecting the presence of a targeted substance in a liquid. For example, the wearable apparatus can be a fingernail that detects illicit drugs in a beverage. The wearable apparatus comprises a detection layer comprising an indicator that is configured to display a signal upon the detection of an interaction with the targeted substance. In some examples, the wearable apparatus can include a lateral flow assay.

An absorbent article having an outer cover with an interior surface and an opposite exterior surface, an absorbent core positioned adjacent the interior surface of the outer cover, and a wetness indicator graphic located on the outer cover. The wetness indicator graphic has a permanent graphic defining at least one non-printed area and a changing graphic located within the at least one non-printed area of the permanent graphic such that the permanent graphic and the changing graphic together give the appearance of a uniform graphic.
