AI Technical Summary
Current absorbent articles face challenges in achieving effective bodily exudate handling with smaller apertures and lower open areas, as larger apertures are required for rapid acquisition, while smaller apertures are desired for softness and aesthetics, and existing dual-layer topsheets increase costs and complexity.
A single-layer web or topsheet with discrete zones of modified surface energy, comprising bicomponent fibers where hydrophobic and hydrophilic components are strategically exposed to create hydrophilic or hydrophobic regions, allowing for efficient exudate handling without topical surface energy treatments.
This solution enables absorbent articles to maintain effective exudate handling with smaller apertures, enhancing softness and aesthetics while reducing material costs by using a single layer instead of dual layers, and improving exudate distribution.
