Replaceable absorbent channel diaper for use as a multiplier with single-use disposable diapers or re-usable recyclable outer shell
11337869 · 2022-05-24 ·

A multi-piece diapering system is based on a removable, disposable absorbent channel insert diaper having hydrophobic interior leg gathers and a water impermeable backer, but without waist tabs or bands or elastic to secure the channel to the user and optionally without leg cuffs. The absorbent channel insert may be used in a single-use disposable diaper to allow such disposable diaper to be re-used multiple times by replacing the channel insert diaper when soiled. The absorbent channel insert diaper may also be used with underwear as the supporting shell, or with other exterior diaper shells or base layer diapers.

Garments and associated methods

Garments and associated methods are disclosed. In examples, a garment includes an absorbent assembly bonded to a body portion. In examples, the absorbent assembly includes an absorbent layer and overlies at least a central region of the body portion. In examples, the absorbent assembly is at least partially bonded to the body portion with elastic bonding film. In examples, the garment is configured to be washed and re-worn numerous times. In examples, a method of manufacturing a garment includes arranging an absorbent assembly over at least the central region of the body portion and bonding the absorbent assembly to the body portion with strips of elastic bonding film and without stitching. In examples, a moisture-absorbent garment includes a body layer supporting an absorbent assembly within a central region and strips of elastic bonding film that bond at least a portion of the absorbent assembly to the body layer without stitching.

ABSORBENT ARTICLE

An absorbent article has a front region, a back region, and a crotch region extending between and connecting the front region and the back region. A non-rectangular absorbent core is located in the absorbent article wherein a portion of the absorbent core is positioned in an overlapping relationship with an elastic material located in at least one of the front region or back region. The non-rectangular absorbent core has a narrowest width dimension in the transverse direction of the absorbent article which is offset from each of the transverse axis of the absorbent article and the narrowest width of the absorbent article. Longitudinally extending elastic material located in the crotch region of the absorbent article is positioned in a spaced apart relationship to the longitudinal direction side edges of the absorbent core.

ABSORBENT ARTICLE WITH IMPROVED FLUID CONTAINMENT AND COMFORT

The present invention relates generally to absorbent products, and, more particularly, to disposable absorbent articles that provide improvements in the containment of bodily fluid secretions. The fluid containment improvements are the result of adding one or more waist barriers to the topsheet of various absorbent articles. Adding waist barriers to the disposable absorbent articles will decrease fluid leakage at the front, back, or both waist areas of the user. In addition, the waist barrier may be made of a soft and lofty foam, which will improve comfort for and reduce irritation to the user's skin. The waist barrier may improve the comfort of the user during nap time, overnight, or whenever the user is lying on their back or stomach. The waist barrier may include one or more sustainable materials.

An absorbent article includes: an absorbent main body including an absorbent core; and leak-proof walls on respective widthwise side portions of the absorbent main body. Each leak-proof wall is capable of standing on a skin side in the thickness direction, and includes a skin-side portion and a non-skin-side portion. A joined part is formed by joining at least partially facing surfaces of the skin-side and non-skin-side portions. The absorbent main body includes a crotch stretchable portion in a central portion in the width direction and the longitudinal direction, and the crotch stretchable portion stretches/contracts in at least one of the longitudinal direction and the width direction. The joined part is provided inside a distal end of the leak-proof wall and outside the crotch stretchable portion in the width direction. A part of the joined part and a part of the crotch stretchable portion at least overlap in the longitudinal direction.

Methods and apparatuses for making elastomeric laminates with elastic strands unwound from beams

The present disclosure relates to methods for assembling elastomeric laminates, wherein elastic material may be stretched and joined with either or both first and second substrates. A first beam is rotated to unwind a first plurality of elastic strands from the first beam in the machine direction. The first plurality of elastic strands are positioned between the first substrate and the second substrate to form the elastomeric laminate. Before the first plurality of elastic strands are completely unwound from the first beam, a second beam is rotated to unwind the second plurality of elastic strands from the second beam. Subsequently, the advancement of the first plurality of elastic strands from the first beam is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first beam to a subsequently utilized elastic material drawn from the second beam.

Elastomeric laminate with activation thickness

An elastomeric laminate is extensible in a first direction and has a first laminate surface; a second laminate surface substantially opposite the first laminate surface; and a laminate thickness, T, extending between the first and second laminate surfaces. A pre-SELFed coverstock layer forms the first laminate surface. The pre-SELF coverstock layer has a primary activation pattern, wherein the primary activation pattern includes SELF-specific land areas that extend in the first direction and one or more activation thicknesses. Each activation thickness is less than the laminate thickness, T. The elastomeric laminate also has an elastomeric layer joined to the pre-SELFed coverstock layer. The elastomeric layer forms the second laminate surface. The elastomeric laminate may be a zero strain laminate, a gathered laminate, or a hybrid gathered laminate.

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. Aspects of the methods for assembling elastomeric laminates may utilize elastic strands supplied from beams that may be joined with first and second substrates, and may be configured to carry out various types of operations, such as bonding and splicing operations.

METHODS AND APPARATUSES FOR MAKING ELASTOMERIC LAMINATES WITH ELASTIC STRANDS PROVIDED WITH A SPIN FINISH
20230301840 · 2023-09-28 ·

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. The elastomeric laminates may include a first substrate, a second substrate, and an elastic material located between the first and second substrates. During assembly of an elastomeric laminate, a beam is rotated to unwind the elastic strands from the beam, wherein the strands may include a spin finish. First bonds are applied to bond discrete lengths of the stretched elastic strands with and between the first substrate and the second substrate, wherein the discrete first bonds are arranged intermittently along the machine direction. In addition, second bonds are applied between consecutive first bonds to bond the first and second substrates directly to each other, wherein the second bonds extend in the machine direction and may be separated from each other in a cross direction by at least one elastic strand.
