Wearable article having elastic belt
Disclosed is a wearable article comprising a main body and a ring-like elastic belt comprising a front belt and a back belt. At least some of the elastic bodies may be arranged in an array, the array defined as meeting: a) one array is formed by 2-10 elastic bodies; b) each elastic body within one array is disposed in an inner-interval between each elastic body of 2-4 mm; and c) one specific array disposed in an extra-interval between at least one neighboring elastic bodies outside the specific array of greater than the inner-interval. Further, the front belt may comprise at least 5 arrays.
Absorbent article with an ear portion
An absorbent article includes a first waist region, a second waist region, and a crotch region disposed between the first and second waist regions. The article further includes a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet; and an ear. The ear includes a laminate having a first nonwoven and second nonwoven and an elastomeric material sandwiched between said first and second nonwovens. The laminate comprises a plurality of ultrasonic bonds. The ear also has a first inelastic region and an elastic region. The ear is joined to the chassis in the first inelastic region, and a fastening system is joined to the ear in the elastic region.
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 methods and apparatuses may be configured with a plurality of elastic strands wound onto a beam, wherein one or more elastic strands comprises a spin finish. During assembly of an elastomeric laminate, the beam is rotated to unwind the elastic strands from the beam. A portion of the spin finish may be removed from the advancing elastic strand with a spin finish removal apparatus. The spin finish removal apparatus may be configured to apply detergent to an advancing elastic strand and may also wipe and/or dry the advancing elastic strand. The treated stretched elastic strand may then be connected between a first substrate and a second substrate. In some configurations, adhesive may be applied to the treated the elastic strand, the first substrate, and/or the second substrate.
ABSORBENT ARTICLE WITH LEG GASKETING CUFF
A disposable absorbent article may include a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet, and a leg gasketing system. The leg gasketing system may include an inner cuff and an outer cuff. The inner cuff may include an inner cuff folded edge and an inner cuff material edge and the outer cuff may include an outer cuff folded edge and an outer cuff material edge such that the web of material is folded laterally inward to form the outer cuff folded edge and folded laterally outward to form the inner cuff folded edge.
PANT-TYPE WEARABLE ARTICLE
A wearable article includes a front and back elastic belts, a crotch region, a waist opening, and leg openings. Each elastic belt is a laminate having an inner sheet, an outer sheet, and an elastic member. Elastic adhesive bonding continuously bonds the elastic member for at least about 10 mm in the direction of stretch adjacent the side edges of the belts. A discrete patterned adhesive bonding is applied to at least one of the inner and outer sheets to intermittently bond the inner and outer sheets. The discrete patterned adhesive bonding extends substantially along the transverse direction between the elastic adhesive bonding, and substantially along the longitudinal direction between the distal and proximal edges of the elastic belts. The same adhesive agent provides the elastic adhesive and discrete patterned adhesive bonding. Heat bonds form side seams, and the remainder of the laminate is free of heat bonds.
Elastic laminates with curved elastics and methods for manufacturing
Elasticated materials and articles comprising elasticated materials are disclosed. A method may comprise advancing first and second substrate materials and a stretched elastomeric strand in the machine direction. The method may further comprise advancing the first and the second substrate materials with the elastomeric strand positioned therebetween to a bonding apparatus. The bonding apparatus may comprise first and second elements forming a bonding nip. The method may further comprise oscillating the strand in a cross-machine direction and advancing the first and second substrate materials, and the strand, through the bonding nip and bonding the first and second substrate materials together with at least first and second bonds. The first and second bonds may be disposed on opposite sides of the strand and spaced apart a distance less than its un-tensioned diameter, and the first and second bonds may be located along an arcuate portion of the strand.
PANT STRUCTURE WITH EFFICIENTLY MANUFACTURED AND AESTHETICALLY PLEASING REAR LEG PROFILE
A disposable absorbent pant having a front belt portion and a rear belt portion is disclosed. The front and rear belt portions are joined at side seams and the rear belt portion has a greater length than the front belt portion. A lower edge of the rear belt portion forms at least in part edges of left and right leg openings to the rear of the side seams. The rear belt portion includes first and second layers of nonwoven web material sandwiching a plurality of laterally extending and laterally pre-strained elastic strands, disposed below the side seams. A first of the plurality of elastic strands differs from a second of the plurality of elastic strands by one or more of amount of pre-strain, tensile modulus, decitex, and combinations thereof.
WEARABLE ARTICLE HAVING ELASTIC BELT
Disclosed is a wearable article continuous in a longitudinal direction and a transverse direction comprising an elastic belt region, a crotch region, a waist opening and two leg openings; wherein the elastic belt region is a laminate comprising an inner sheet made of nonwoven fiber, and an outer sheet made of nonwoven fiber, and a plurality of elastic bodies configured to stretch the elastic belt region in the transverse direction, wherein the article has a Compression Work index of at least about 70 gfcm and a Stretch Circumference Force of less than about 6.5N according to the measurements herein.
Methods and Apparatuses for Making Elastomeric Laminates
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.
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.
