FEMALE COMPONENT FOR REFASTENABLE FASTENING DEVICE-Arm parts for refastenable fasteners, refastenable fasteners and disposable absorbent products

摘要

The present invention provides a refastenable fastening device that includes a female fastening component 12 that preferably includes a substrate web 53 and a bonding layer 54. The substrate web 53 includes a structurally elastic film (SELF) web 52 and is bonded to a bonding layer having a plurality of filament or nonwoven webs. SELF web 52 exhibits elastic properties in the stretch direction without the use of additional elastic materials. SELF webs comprise a strainable network having at least two different regions comprising a composition of the same material. The first region 64 is oriented parallel to the stretching axis, so that a substantial portion of the second region 66 is parallel to the stretching axis before first receiving a geometrical deformation according to stretching applied in a direction parallel to the stretching axis. Undergoes molecular-level deformation along the axial stretch applied. The second region 66 includes a number of elements 74, such as raised ribs, which elements like ribs 74 are more effective with improved ability to entangle with complementary male hooks. Work with the filament or nonwoven web to provide a female part.
