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 cm 2 /( Pa s) and a specific volume of at least 5 cm 3 /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. The disposable absorbent article further comprises a topsheet, a backsheet and substantially cellulose free absorbent core comprising first and second absorbent layers, comprising superabsorbent particulate polymer material deposited on substrates and covered by thermoplastic adhesive material. |
