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 article and method and device for manufacturing absorbent article
An absorbent article having a lateral direction, a vertical direction, and a front-rear direction that are orthogonal to each other is provided. The absorbent article includes: a first sheet-like member; a second sheet-like member; elastic members that are inserted along the lateral direction between a pair of mutually-opposing facing surfaces of the first sheet-like member and that are spaced apart in the vertical direction; joining portions that join the pair of mutually-opposing facing surfaces and that are spaced part in the lateral direction and in the vertical direction; and side-seal sections disposed at each lateral end portion of the absorbent article. The joining portions are formed on two sides of the elastic members in the vertical direction so that the elastic members are sandwiched and pressed between the joining portions on the two sides.
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 ARTICLE HAVING BREATHABLE SIDE FLAPS
A disposable absorbent article having a topsheet; a backsheet; and an absorbent core disposed between the topsheet and the backsheet, is described. The disposable absorbent article includes a first side edge and an opposing second side edge; a first side flap and an opposing second side flap, each of the first and second side flaps forming at least a portion of the wearer-facing surface, each of the first and second side flaps having a first layer and a second layer. The first layer has a first layer proximal edge and the second layer has a second layer proximal edge. The second layer proximal edge is disposed laterally outboard from the first layer proximal edge.
Stretchable structure of absorbent article and manufacturing method of the same
A stretchable structure of an absorbent article has a first sheet layer of a nonwoven fabric; a second sheet layer of a nonwoven fabric and opposed to one side of the first sheet layer. A plurality of elongated elastically stretchable members are provided along the stretchable direction at intervals from each other between the first sheet layer and the second sheet layer. The first sheet layer and the second sheet layer have sheet bonded portions bonded via a hot melt adhesive disposed in a striped pattern that is intermittent in the longitudinal direction of the elastically stretchable members and continuously elongated in the direction intersecting with the elastically stretchable members. One of the first sheet layer and the second sheet layer is a spunbond nonwoven fabric, and the other sheet layer is an air-through nonwoven fabric whose surface on the spunbond nonwoven fabric side is a fluffy surface.
Absorbent articles comprising stretch laminates
An absorbent article includes a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, and at least one elastically elongatable panel joined to the chassis. The elastically elongatable panel includes an ultrasonically bonded stretch laminate. The stretch laminate has at least one cover layer; and an elastomeric film having two surfaces and a skin on at least one of the surfaces. The stretch laminate has a first zone that is not elastically extensible along a stretch direction and a second zone that is elastically extensible along the stretch direction; and at least a portion of the skin of the elastomeric film is located in the first zone and wherein said portion of the skin has a plurality of wrinkles and the wrinkles have furrows.
Underpants-type disposable diaper
An underpants-type disposable diaper separately has a front side outer member and a back side outer member, the front side outer member and the back side outer member being spaced apart in a front-back direction in a middle in the front-back direction The back side outer member has a gluteal cover portion extending to a center side of the side seal portions in the front-back direction, and a front-back direction dimension of a side edge of the gluteal cover portion is 0.9 to 1.1 times a width direction dimension from a side edge of the back side outer member to a side edge of a center side of the side seal portions in the width direction.
BEAMED ELASTOMERIC LAMINATE STRUCTURE, FIT, AND TEXTURE
The present disclosure relates to stranded elastomeric laminates (including bi-laminates and tri-laminates) comprising beamed elastics and may have inventive Dtex-to-Nonwoven-Basis-Weight-Ratios, Dtex-to-Spacing-Ratios, and/or Void-Area-to-Strand-Area-Ratios. The stranded laminates of the present disclosure may be used for disposable absorbent article components (including pant belts) and may comprise inventive bonding arrangements that yield inventive textures and texture arrangements. When the inventive stranded elastomeric laminates are used for pant belts, the pants may have inventive Application-Forces, Sustained-Fit-Load-Forces, and Sustained-Fit-Unload-Forces. Further, when absorbent articles are packaged under compression at inventive In-Bag-Stack-Heights, the stranded elastomeric laminates of the present disclosure maintain their inventive properties and characteristics, including their inventive textures.
Apertured elastic film laminates
An elastic laminate is provided including at least one gathered outer facing layer of a fabric and an apertured elastic film attached thereto. The aperture film includes a series of alternating first and second segments that extend continuously along the direction of elasticity. The first segments of the film are substantially devoid of any apertures and the second segments are strewn with apertures of irregular size and shape. The regionally limited and irregular apertures are formed by the controlled rupturing of the film within those segments. The elastic laminate has excellent air-permeability and elastic properties.
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.
