LA PRESENTE INVENCION ESTABLECE UN ARTICULO DISTINTIVO QUE INCLUYE AL MENOS UNA CAPA DE TELA FIBROSA Y ABSORBENTE QUE ES SUSTANCIALMENTE NO HIDROENTORPECIDA. LA CAPA DE TELA FIBROSA PUEDE TENER UN PESO BASICO DE AL MENOS ALREDEDOR DE 60 G Y UNA DENSIDAD MAXIMA DE AL MENOS ALREDEDOR DE 0,25 G/CC. LA CAPA DE TELA FIBROSA PUEDE TENER ADEMAS UNA MEDIA GEOMETRICA PICO DE RESISTENCIA A LA TRACCION DE AL MENOS ALREDEDOR DE 250 GRAMOS DE FUERZA POR CENTIMETRO DE ANCHURA, Y PUEDE TENER UN CONTENIDO DE FIBRA EN EL QUE AL MENOS ALREDEDOR DEL 90 % EN PESO DE LAS FIBRAS ESTEN COMPUESTAS DE FIBRAS QUE TENGAN UNA LONGITUD NO SUPERIOR A ALREDEDOR DE 0,4 PULGADAS (ALREDEDOR DE 1 CM). EN CONFIGURACIONES PARTICULARES, EL ARTICULO INCLUYE UNA CAPA POSTERIOR Y UNA CAPA SUPERIOR PERMEABLE A LOS LIQUIDOS QUE SE DISPONE FRENTE A LA CAPA POSTERIOR. SE INTERPONE UNA ESTRUCTURA ABSORBENTE ENTRE LA CAPA POSTERIOR Y LA CAPA SUPERIOR, Y LA ESTRUCTURA ABSORBENTE TIENE UNA CAPACIDAD TOTAL DE ABSORCION DE AL MENOS ALREDEDOR DE 300 GRAMOS DE SOLUCION SALINA. 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.
