A disposable undergarment is disclosed. The undergarment includes a chassis and an absorbent core assembly. The chassis includes a front section, a crotch section and a rear section. The absorbent core is located in the crotch section, with portions of it extending into the front and rear sections. A large plurality of closely spaced elastic threads extends across the full width of the undergarment in the front and rear sections. A large plurality of closely spaced elastic threads extends across the full width of the undergarment in portions of the crotch section adjacent the front and rear sections. The elastic threads are broken in the areas of the core assembly. The core assembly includes a first section of a slow acting but high absorbency SAP in pockets thereof and an underlying second section of a fast acting by lower absorbency SAP in pockets thereof.

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.

The present disclosure relates to wearable articles having an elastic belt having arrays of elastic bodies.

A disposable wearable article includes an elastic film stretchable structure in which an elastic film is laminated between a first sheet layer and a second sheet layer. The first sheet layer and the second sheet layer are bonded to each other through holes passing through the elastic film with many bonded portions arranged at intervals. A region having the elastic film stretchable structure includes a stretchable region that elastically stretches and contracts together with the elastic film. The stretchable region includes a plurality of elastic films disposed so as to have an overlapping portion. The number of laminated layers of the elastic film in a region located in an intermediate portion of the stretchable region in an orthogonal direction (XD) orthogonal to a stretchable direction (ED) is different from that in each of second regions adjacent to both sides of the first region.

An elastic sheet stretchable structure in which a first sheet layer and a second sheet layer are bonded through joint holes penetrating an elastic film at a plurality of sheet joined portions arranged at intervals is included. Joined portion groups in the stretchable region are in a relationship of intersecting a stretchable direction line at respective positions in an orthogonal direction or in a relationship of not intersecting the stretchable direction line at a separation width of 0.5 mm or less in the orthogonal direction of the stretchable direction line. The joined portion groups are in a relationship of not intersecting an oblique line at a predetermined separation width in the orthogonal direction in an oblique line group of oblique lines q in the orthogonal direction intersecting the stretchable direction line within an angle range γ of 45 degrees or less.

An absorbent article, such as, a garment-like absorbent article, can have a front region, a back region, and a crotch region extending between and interconnecting the front region and the back region. Each of the front region and the back region can have an elastic material. The absorbent article can have an absorbent core wherein a portion of the absorbent core can be located in the crotch region, a portion of the absorbent core can be located in a portion of the front region, and a portion of the absorbent core can be located in a portion of the back region. Within each of the front region and the back region, an overlapping region can exist where the absorbent core is in an overlapping configuration with the elastic material within the front region and the back region.

Disclosed is a wearable article comprising a front elastic belt region, a back elastic belt region, each of the front and back elastic belt region comprises a laminate comprising an inner sheet, an outer sheet, and a plurality of elastic members running in the transverse direction, the longitudinal dimension between adjacent elastic members forming an elastic spacing; wherein the laminate is bonded by heat at the side edges to form side seams, the side seams existing no distant than about 20 mm from the side edges, and the remainder of the laminate is substantially free of heat bonds, wherein the article has a Belt Elastic Bonding Percentage of less than about 25%, and an Individual Elastic Bonding Percentage of from about 10% to about 75%, according to the measurements herein.

The present disclosure relates to wearable articles having an elastic belt having arrays of elastic bodies.

Further, the front belt may comprise at least 5 arrays.

An absorbent article is described that includes leg elastics that form the outermost edges of the product. The leg elastics can include an increased number of elastomeric strands and can extend outboard of the chassis. In this manner, the leg elastics can form a proper seal with the legs of the wearer without interference and can be visually inspected by a caregiver. Placing the leg elastics outboard of the chassis also provides for an efficient manner of producing the garment by attaching multiple elastic components to the garment along a vertical bonding seam.
