The second article has a second elastic component configured for providing fit and comfort to a female user. The first and the second elastic components each have a plurality of elastic elements extending at least partly along each respective article. The first and second elastic components differ from each other in at least the positioning or the elastic strength of the respective elastic elements. A method for manufacturing the array is also provided.
BEAMED ELASTIC LAMINATE PROPERTIES
The present disclosure relates to one or a combination of an absorbent article's chassis, inner leg cuffs, outer leg cuffs, ear panels, side panels, waistbands, and belts that may comprise one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or low Average-Dtex (less than 300, less than 200, less than 100 dtex) and/or low Average-Pre-Strain (less than 300%, less than 200%, less than 100%) elastics to deliver low Pressure Under Strand (less than 1 psi according to the conditions defined by the Pressure-Under-Strand Test), while providing adequate Section-Modulus (between about 2 gf/mm and 15 gf/mm) to make the article easy to apply and to comfortably maintain the article in place on the wearer, even with a loaded core (holding at least 100 mls of liquid), to provide for the advantages described above. Further, the elastomeric laminates of the present disclosure outperform existing laminates currently used for disposable absorbent articles as it relates to one or more key parameters (including Percent Contact Area, 2-98% Height Value, Pressure-Under-Strand, Air Permeability, Water Vapor Transmission Rate, Caliper, Caliper Retention Value, Cantilever Bending, Open Area, Section-Modulus, Rugosity Wavelength, Rugosity Frequency, Graphic Distortion Ratio).
Disposable pull-on garment
An absorbent article having a longitudinal centerline, a front region, a crotch region, and a back region. The absorbent article has a main portion, a side portion, and a waist portion. The waist portion has a belt portion that has a front belt portion having elastomeric material and a back belt portion having elastomeric material. The front belt portion has a first elastic section and a second elastic section, each section having force zones. The back belt portion has a third elastic section and a fourth elastic section, each section having force zones. The force zones in the portions alternate between a high force zone and a low force zone in at least one belt portion.
Pant structure with efficiently manufactured and aesthetically pleasing rear leg edge profile

The first bond forms a first angle with respect to the first strand, the third bond forms a second angle with respect to the second strand, and the first angle is different than the second angle.
METHODS OF MAKING LAMINATES FOR ABSORBENT ARTICLES
A method of making a laminate for an absorbent article is provided. The laminate comprises elastic elements disposed at least partially intermediate two substrates. The first substrate has a primary fiber bond pattern formed therein and comprising a plurality of primary fiber bonds. The method comprises forming densified regions in the first substrate. A perimeter of each of the densified regions is larger than a perimeter of each of the primary fiber bonds. The densified regions together form a pattern of densified regions in the first substrate. The method comprises adhesively attaching the elastic elements to the first substrate, joining the second substrate to the first substrate or to some of the elastic elements, and forming a plurality of rugosities in the first substrate by allowing the elastic elements to at least partially contract. The frequency and amplitude ranges of the rugosities result from the pattern of the densified regions.
