Abstract
Disclosed is a lightweight nonwoven laminate particularly useful as a component of personal care articles, for example as a barrier cuff material for disposable diapers. Components of the laminate include at least one fine fiber layer having a basis weight in the range of from about 1.5 gsm to 26 gsm and at least one continuous filament layer having a basis weight in the range of from about 10 gsm to 30 gsm. The fine fiber component comprises at least a ratio of 5% and the layers are intermittently bonded for a total basis weight up to about 55 gsm. Desirable softness, breathability and barrier properties are obtained.
Claims19
In a disposable garment utilized for the absorption and containment of urine or other body exudates comprising a liquid pervious bodyside liner, a fluid impervious backing sheet with an absorbent material disposed therebetween and having flap means for enhanced containment,
- the improvement wherein the means for enhanced containment comprises a nonwoven fabric laminate comprising:
- a) a nonwoven component layer comprising fine fibers having an average diameter in the range of up to about 10 microns and a basis weight of at least about 1.5 gsm, and
- b) a nonwoven component layer comprising continuous filaments having an average diameter in the range of from about 12 microns to about 22 microns and a basis weight of at least about 5 gsm,
- wherein said layers are intermittently bonded in a face-to-face relationship for a total basis weight not to exceed about 55 gsm and the percent of the weight of fine fibers layer to the laminate weight is at least 5%, and
