摘要:
The present invention provides a distinctive article which includes at least one absorbent, fibrous web layer which is substantially non-hydroentangled. The fibrous web layer can have a basis weight of at least about 60 gsm, and a density of not more than about 0.25 gm/cc. The fibrous web layer can further have a peak geometric mean tensile strength of at least about 250 grams-force per centimeter of width, and can have a fiber content in which at least about 90 wt % of the fibers are composed of fibers having a fiber length of not more than about 0.4 inch (about 1 cm). In particular configurations, the article includes a backsheet layer, and a liquid permeable topsheet layer which is disposed in facing relation with the backsheet layer. An absorbent structure is interposed between the backsheet layer and the topsheet layer, and the absorbent structure has an overall absorbent capacity of at least about 300 grams of saline.
