Apertured hydrophilic polymer film topsheet with improved absorbency and
comfort properties
摘要:
An improved topsheet for use in absorbent articles such as sanitary pads. The topsheet comprises a three-dimensional hydrophilic formed film having a plurality of openings leading from a surface of the topsheet to an absorbent core. The topsheet presents a more comfortable and dryer surface which contacts the wearer and a clean, dry appearance to the wearer. The clean, dry appearance is obtained by employing an opacifying agent in the film. The openings comprise tapered capillaries having a base in the surface plane of the topsheet and an apex remote from the surface plane of the topsheet. Each apex is in intimate contact with the absorbent core. In a preferred arrangement, the hydrophilic polymer film topsheet comprises Nylon 6, Nylon 6 and polyetheramide, or other resins having chemistries similar to nylon.
