Title: (EN) Fluid Permeable Structured Fibrous Web
Abstract: front page image
(EN)

A disposable absorbent article having a fluid permeable structured fibrous web with thermally stable, fibers that are thermally bonded together using heat provides a base substrate that is thermally stable. The base substrate is textured via mechanical treatment producing a structured fibrous web having an aged caliper of less than 1.5 mm, a vertical wicking height of at least 5 mm, a permeability of at least 10,000 cm2/(Pa·s) and a specific volume of at least 5 cm3/g. The structured fibrous web provides optimal fluid wicking and fluid acquisition capabilities and is directed toward fluid management applications. The structured fibrous web has a bio-based content of about 10% to about 100% using ASTM D6866-10, method B.
