Abstract: The present invention is a disposable absorbent undergarment, such as an adult brief or baby diaper, having an exterior surface designed to provide improved attachment for one or more fastener members, thereby resulting in improved closure and securement of the undergarment to a 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: 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 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.

Abstract: The present invention methods for manufacturing absorbent articles that involve the placement of absorbent cores having variable absorbency levels on consecutively aligned absorbent articles within the same manufacturing line. Additionally, the present invention also includes the provision of single packages of disposable absorbent articles that contain a first absorbent article having a first absorbency level and a second absorbent article having a second absorbency level, wherein the second absorbency level is higher than the first absorbency level.

Abstract: An absorbent article comprising a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent structure positioned in between said topsheet and said backsheet, wherein the absorbent structure comprises an absorbent core positioned in between the topsheet and the backsheet, a release structure being positioned in fluid communication with the absorbent core, said absorbent core comprising little to no cellulose fibers and/or fluff pulp and said absorbent core comprising an absorbent polymer material for absorbing and permanently holding fluids received from the topsheet and the release structure, wherein said release structure comprises at least one fibrous substrate structure having the capacity to receive and temporarily hold the fluids in proximity to the absorbent core so that the fluids can subsequently be transferred and released to and absorbed by the absorbent core.

Abstract: An absorbent article such as a diaper can include three or more absorbent core structures for improved acquisition speed, reduced bulkiness, increased retention capacity, and improved dryness, including over multiple insults. The three or more absorbent core structures can at least partially overlap in a stacked or layered configuration in an insult zone of the article. At least one of the core structures can include an absorbent polymer or airlaid material. The absorbent polymer can be located primarily in the insult zone, and one or more of the absorbent core structures can extend beyond the insult zone. In an example, each of the at least three absorbent core structures has a different body-side surface area.

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: An absorbent article comprising a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core positioned between the liquid pervious topsheet and the liquid impervious backsheet; said absorbent article having a first and second longitudinal edge and a first and second transverse edge; wherein the absorbent core comprises a top core sheet, a back core sheet, and absorbent material arranged partially between the top core sheet and the back core sheet; wherein at least one of the top core sheet and the back core sheet comprises at least one attachment portion which is attached to the other one of the top core sheet and the back core sheet forming at least one attachment zone, and at least one edge portion having at least one free edge and covering a portion of the absorbent material.

Abstract: The present invention relates to a method and apparatus for forming a composite structure, preferably for use in an absorbent structure used within the personal hygiene industry, such as for instance feminine hygiene garments, baby diapers and pants and adult incontinence garments. The present invention preferably provides a method and apparatus for depositing and positioning particulate materials in a desired pattern onto a moving carrier layer. The method allows accurate forming of a pattern of particulate material clusters at high production speed having improved attachment properties, with reduced raw material usage and relative low cost. The present invention foresees in the need for improved thin, flexible, lightweight absorbent structure having optimal absorption, distribution and retention.

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.
