摘要:
Filaments that contain a filament -forming material and an additive, nonwoven webs, and methods for making such filaments are provided. The level of one or more additives in the filament is 50% or more weight on a dry filament basis.
摘要:
A paper web of the present invention has a longitudinal centerline (L) and a transverse centerline (T), and comprises a plurality of first regions (60) and a plurality of second regions (66). The first regions (60) form boundaries separating the second regions (66), the first regions (60) being substantially in a plane of the paper web. The second regions (66) comprise a plurality of raised out-of-said-plane rib-like elements (74), the rib-like elements (74) of each second region being disposed parallel to a major rib axis and perpendicular to a minor rib axis. All or most of each first regions have both major rib axis and minor rib axis components. The first and second regions undergo geometric deformation when the web material is subjected to an applied elongation along at least one axis. A method of the present invention comprises the steps of providing a cellulosic substrate; providing a first platen (402) comprising toothed regions (407) and untoothed regions (408); providing a second platen (401) comprising toothed regions, the second platen (401) being aligned with the first platen such that the toothed regions of the first and second platens mesh when operably engaged; and pressing the cellulosic substrate between the first platen and the second platen such that the toothed regions deform said web to form regions of discrete fan-folded rib-like elements. Optionally, the cellulosic substrate can be moistened prior to the pressing step.

摘要:
Thermally bonded absorbent structures for catamenial products, in particular catamenial pads, that provide improved ability in acquiring, distributing and storing aqueous body fluids, especially menstrual fluids, as well as better fit and comfort for the user of the products. These structures comprise an optional thermally bonded secondary topsheet, a thermally bonded absorbent core having a relatively higher capillary suction primary fluid distribution layer, an optional but preferred relatively lower capillary suction secondary distribution layer, a storage layer having absorbent gelling material, and an optional fibrous 'dusting' layer. These thermally bonded absorbent structures are particularly useful with catamenial pads having a primary fluid pervious topsheet selected from apertured formed film topsheets and high loft nonwoven topsheets.
