    摘要： 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).

    摘要： 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.
