ABSORBENT ARTICLE WITH CONFORMING FEATURES
An absorbent has longitudinal and lateral centerlines, first, second, and target regions, the target region being disposed between the first second regions. Each of the first, second target regions extend laterally across the disposable absorbent article. The disposable absorbent article also has a topsheet; a backsheet; an absorbent core disposed between the topsheet and backsheet; a fluid management layer disposed between the topsheet and absorbent core; and a target zone disposed in the target region. The target zone has a first plurality of conforming features in at least the absorbent core or a combination of the absorbent core and at least one of the topsheet or fluid management layer. The absorbent article also has a long fiber network.
Absorbent pad
To provide an absorbent pad, the absorbent pad being formed of an inner absorbent pad which is positioned on the body-side and an outer absorbent pad positioned on the non-body side, wherein when the inner absorbent pad absorbs liquid excretions and swells, openings are provided at the side which is indented furthest towards the non-body side, improving the passage of liquid, and improving the dispersion of sites facing the openings in the outside absorbent pad, preventing leakage of liquid excretions to the exterior.
Methods and apparatuses for making elastomeric laminates with elastic strands unwound from spools on surface unwinders
The present disclosure relates to methods for assembling elastomeric laminates, wherein elastic material may be stretched and joined with either or both first and second substrates. First spools are rotated to unwind first elastic strands from a first unwinder in a machine direction. The first elastic strands are positioned between the first substrate and the second substrate to form an elastomeric laminate. Before the first elastic strands are completely unwound from the rotating first spools, second spools are rotated to unwind second elastic strands from a second unwinder. Subsequently, the advancement of the first elastic strands from the first unwinder is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first spools to a subsequently utilized elastic material drawn from the second spools.
APPARATUSES AND METHODS FOR MAKING ABSORBENT ARTICLES WITH ELASTOMERIC LAMINATES
The present disclosure relates to methods and apparatuses for making elastomeric laminates with deactivated regions that may be used as components of absorbent articles. The methods and apparatuses may be configured with a pattern roll and a pressing surface adjacent the pattern roll. The pattern roll may include a bonding surface and a protuberance. As the pattern roll rotates, first and second substrates are welded together between the bonding surface and the pressing surface to create bonds between the first and second substrates. As the pattern roll continues to rotate, the first and second substrates and one or more stretched elastic strands are compressed between the pressing surface and the protuberance to sever the one or more stretched elastic strands to create deactivated regions in the elastomeric laminate. The processes and apparatuses may be configured to help prevent ends of the severed elastic strands from retracting in an uncontrolled fashion.

LAMINATE(S) COMPRISING BEAMED ELASTICS AND ABSORBENT ARTICLE(S) COMPRISING SAID LAMINATE(S)
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 very fine (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand method below) under the elastics, while providing adequate modulus of (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 50 mls of liquid), to provide for the advantages described above.
Absorbent article with an absorbent core having longitudinally extending side regions being spaced apart in the transversal direction by at least one longitudinally extending channel region, and method for manufacturing said absorbent article
An absorbent article has a longitudinal direction, a transverse direction and a thickness direction, and includes a fluid permeable topsheet, a fluid impermeable backsheet and an absorbent core enclosed between the topsheet and the backsheet having, in the longitudinal direction, a front section, a rear section and a crotch section between the front section and the rear section. The absorbent core has two longitudinally extending side regions being spaced apart in the transversal direction by at least one longitudinally extending channel region. The channel region is of less basis weight than the side regions.
Absorbent Material, and System and Method of Making Same
A fiber-SAP particle includes a superabsorbent core particle (SAP core particle) and a plurality of fibers attached to the SAP core particle and extending therefrom. The fiber-SAP particles may be formed in a fluidized bed chamber using a spray drying process. The fiber-SAP particles may be incorporated into absorbent cores and articles, such as in disposable diapers.
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.
