Embodiment approach

[0073] Referring to Figures 1 and 2, a feminine sanitary napkin 20 according to one embodiment of the present invention is shown.

[0074] The sanitary napkin 20 has a main body 22 having a first lateral edge 26 defining a front portion of the main body 22 and a second lateral edge 28 defining a front portion of the main body 22. The rear portion of the main body 22 is defined. The body 22 also has two longitudinal sides, a longitudinal side 30 and a longitudinal side 32 . The sanitary napkin 20 preferably has a thickness of no more than about 2.5 mm, preferably less than 2.0 mm, more preferably less than 1.5 mm.

[0075] The longitudinal centerline 34 of the sanitary napkin 20 is shown in phantom and bisects the sanitary napkin 20 into two identical sections. Flanks 38 and 40 extend laterally outward from each longitudinal edge 30, 32, respectively. The main body 22 also has a transverse imaginary centerline 36 perpendicular to the longitudinal centerline 34, while bisecti...

Embodiment I

[0107] Cover layer embodiment I of the spunlace method of the present invention - A 50 gsm basis weight spunlaced nonwoven web comprising 50% 2.0 dpf Type 130 HyEntangle WA (polypropylene) fibers (from Fibervisions Inc. Covington GA) and 50% 1.4 dpf 300 Series PET fibers ( from Sabic Inc., Sittard (Netherlands)). The 2.0 dpf Type 130 HyEntangle WA fibers are "permanently wettable" fibers.

[0108] Covering layer embodiment II of the spunlace method of the present invention - A 50 gsm total basis weight spunlaced nonwoven web comprising a preformed web of 10 gsm or 20% by weight of spunbond PP introduced prior to the spunlace (from PGI , Inc.Charleston SC code KO-CA-5), and 40gsm or 80% by weight of the total weight of the nonwoven web fabric spinning staple fiber, namely 1.5dpf 203 type PET fiber (from Wellman Inc.Charlotte, NC ). In this example, permanently wettable "fibers" were introduced through a preformed spunbond PP mesh. In this example, the spunbond PP mesh wa...
