METHODS AND APPARATUSES FOR MAKING ELASTOMERIC LAMINATES WITH ELASTIC STRANDS PROVIDED WITH A SPIN FINISH
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.
Disposable absorbent articles
An absorbent article comprising a first and second plurality of elastics. The first plurality of elastics may be disposed in a front and a crotch region. The second plurality of elastics may be disposed in a back region and the crotch region. The first and second plurality of elastics may be linear and parallel with a transverse axis of the article.
ABSORBENT ARTICLES HAVING ABSORBENT LEG CUFFS
This disclosure includes absorbent articles comprising first and second absorbent cuffs to prevent leaks. The present articles can comprise a chassis having opposing front and rear portions and a crotch portion extending longitudinally between the front and rear portions. An absorbent core can extend longitudinally along the crotch portion, and the first and second absorbent cuffs can extend longitudinally along the crotch portion as well. The absorbent cuffs can be positioned such that at least a portion of the absorbent core is positioned between the absorbent cuffs, and each can comprise a liftable portion and one or more elastics configured to urge the liftable portion away from the chassis and toward a wearer when the absorbent article is worn. Absorbent or hydrophobic end caps can extend across the ends of the absorbent cuffs.
Method for Making a Shaped Nonwoven
A method for making nonwoven fabric. The nonwoven fabric can include three-dimensional features that define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property. The nonwoven further has a plurality of apertures, wherein at least a portion of the aperture abuts at least one of the first region and the second region of the microzone.
METHODS AND APPARATUSES FOR MAKING ELASTOMERIC LAMINATES WITH ELASTIC STRANDS
The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. In particular, discrete mechanical bonds are applied to a first substrate and a second substrate to secure elastic strands therebetween, wherein the discrete bonds are arranged intermittently along the machine direction. During the bonding process, heat and pressure are applied to the first substrate and the second substrate such that malleable materials of the first and second substrates deform to completely surround an outer perimeter of a discrete length of the stretched elastic strand. After removing the heat and pressure from the first and second substrates, the malleable materials harden to define a bond conforming with a cross sectional shape defined by the outer perimeter of the stretched elastic strand.
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 gasketing barriers to standing leg cuffs of various absorbent articles. Adding gasketing barriers to the standing leg cuffs will decrease fluid leakage at the leg and crotch area of the user and will improve the comfort of the user.
Shaped nonwoven
A nonwoven fabric. The nonwoven fabric can include a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property. The nonwoven further has a plurality of apertures, wherein at least a portion of the aperture abuts at least one of the first region and the second region of the microzone.
Method and apparatus for manufacturing absorbent sanitary products and an absorbent sanitary product
A method for manufacturing absorbent sanitary products, comprising the steps of: forming a first and a second continuous elastic band, which are movable parallel to each other in a machine direction, fixing a plurality of absorbent panels between said first and second continuous elastic bands, arranged in a direction transverse to the machine direction, and spaced apart in said machine direction, wherein each of said elastic bands is formed by means of a method comprising the steps of: continuously feeding a plurality of tensioned elastic threads (30) in said machine direction, continuously feeding a pair of non-elastic webs arranged on opposite sides of said plurality of elastic threads, welding said pair of non-elastic webs to each other by means of a welding pattern comprising anchoring welds and/or containing and guiding welds.
DISPOSABLE ABSORBENT PRODUCT
First welds each slope downward toward the outer side in the width direction. Second welds each slope downward toward the outer side in the width direction. Third welds each slope upward toward the outer side in the width direction. When one first weld, one second weld, and one third weld that are adjacent to one another in the width direction form one weld group, each weld group is configured such that the upper end of the third weld is located downward of the upper end of the second weld, the upper end of the second weld is located downward of the upper end of the first weld, the lower end of the second weld is located downward of the lower end of the first weld, and an extension line extending outward in the width direction from the second weld intersects with the third weld.
ABSORBENT ARTICLES HAVING TEXTURE ZONES FORMING BACKGROUND PATTERNS AND MACRO PATTERNS
An absorbent article comprises first and second substrates and one or more elastic elements disposed at least partially intermediate the substrates. The second substrate is attached to the first substrate and/or to portions of the elastic elements. The absorbent article comprises an adhesive having a first and second pattern of elements disposed on first substrate, and first and second texture zones. The first texture zone comprises a first portion of the substrates, a first portion of the elastic elements, and the first pattern of elements of the adhesive and forms a background pattern in the first portion of the substrates. The second texture zone comprises a second portion of the substrates, a second portion of the one or more elastic elements, and the second pattern of elements of the adhesive and forms a macro pattern in the second portion of the substrates.
