Abstract: Disposable articles, and, more particularly, a disposable undergarment including a product chassis configured to serve as a basis of a variety of disposable articles, including disposable underwear without an absorbent core, disposable underwear with an absorbent core designed for menstrual use, and disposable underwear or training pant with an absorbent core designed for incontinence use (adult and child). The product chassis is comprised of multiple sections including an elastomeric composite, containing stretch film, coupled to one another, each section is designed to provide stretch in a desired direction, thereby resulting in improved securement of the undergarment to a wearer for optimizing fit and comfort for the wearer, while reducing the risk of leakage as well as reducing the amount overall material required for producing the undergarment.

Abstract: The present invention includes disposable absorbent articles, such as disposable undergarment, diapers, other garments, and wound care dressings, having an elastomeric material disposed between two substrate layers and an absorbent core system that disposed on top of or between the two substrate layers. This invention may also include a disposable article having an elastomeric material disposed between two substrate layers without an absorbent core. The inclusion of an stretch adhesive in the construction of the article in various portions of the article (e.g., fastening tabs, front and/or rear sections, entire article, etc.) results in improved securement of the article to a wearer for reducing the risk of leakage and further improving comfort for the wearer. Furthermore, the inclusion of a stretch adhesive can provide a smooth contoured fit to a wearer, thereby improving appearance and self-confidence for the wearer.

Abstract: A substantially cylindrical, or tubular, garment structure can be provided using a three-dimensional or circular knitting machine, using a mold, or using an additive manufacturing process. A unit segment of the garment structure can include two waistband regions at opposite end faces of the cylindrical garment structure, and each of the waistband regions can correspond to a different one of two nested articles. Each of the two nested articles can be converted into a separate and distinct brief-style absorbent underwear assembly. In an example, a waistband region and body panel region of an absorbent underwear product can be formed using the same knitted material in a continuous, three-dimensional knitting process.

Abstract: A method for manufacturing an absorbent article, said method comprising guiding a first sheet material along a rotating member, wherein a surface of said rotating member is provided with a pattern with at least one suction zone and at least one non-suction zone; applying an absorbent material on said first sheet material on the rotating member; locally removing the absorbent material applied on at least one attachment portion of the first sheet material located above the at least one non-suction zone, such that at least one remaining portion of the first sheet material located above the at least one suction zone is covered with absorbent material and substantially no absorbent material is present on the at least one attachment portion; applying a second sheet material on top of the absorbent material on the first sheet material.

Abstract: The present invention relates to an absorbent structure, preferably for use in absorbent products, such as used in the food, consumer, household, building and construction, beauty and medical industry, and as used in the personal hygiene industry. The substantially cellulose free absorbent structures continuously immobilise absorbent polymer material via initial smaller pockets and subsequently larger compartments allowing excellent fluid management of the absorbent polymer material in dry, partially and fully liquid loaded state. Preferably such absorbent structure volume increases are result of temporary secondary attachment patterns made in combination with substantially permanent primary attachment grids allowing the release of bigger volumes from the initial smaller volumes by detachment of the secondary attachments.
