    Abstract: The present disclosure is directed to disposable absorbent articles comprising a structured fibrous web, the structured fibrous web comprising thermally stable, hydrophilic fibers that are thermally bonded together using heat producing a base substrate that is thermally stable. The base substrate is textured via mechanical treatment to increase its thickness and optionally modified via over bonding to improve its mechanical and fluid handling properties. The structured fibrous web provides optimal fluid wicking and fluid acquisition capabilities and is directed toward fluid management applications.

    Abstract: A method and apparatus is provided which uses activation members for incrementally stretching a web at a low strain rate. The activation members include an activation belt and a single activation member wherein the activation belt and single activation member comprise a plurality of teeth and grooves that complement and engage one another at a depth of engagement in a deformation zone. The depth of engagement can be controlled to increase linearly over at least a portion of the deformation zone such that a web interposed between the activation belt and the single activation member in the deformation zone is incrementally stretched at a low rate of strain.
