Abstract

Una tela compuesta laminada (70) adecuada para utilizar como hoja superior (38) para un artículo absorbente (20). La tela es un laminado de dos materialespermeables a líquidos, el primero de los cuales es una tela no tejida perforada hidrofoba (210)con un área eficaz provista de aberturas (204) con un tamanoeficaz en tanto que el segundo material es una película formada macroscopicamente expandible (250) con un área abierta eficaz. La película formada estáprovista de capilares (241) definidosp or porciones de pared lateral interconectadas. El tamano eficaz de los capilares es tal que cada abertura de la tela notejida circunscribe una porcion, por lo menos, de dos o más capilares. Se trata, preferentemente, la superficie exterior delmateri al no tejido con untratamiento superficial con una energía superficial menor que la energía superficial del material no tejido. También, artículos absorbentes utilizan la telalaminada como hoja superior y un método para fabricar la telalaminada en e l cual se crea una pluralidad de lugares debilitados estabilizados por fusion que serompen luego, creando una pluralidad de aberturas no tejidas en la tela, y se une una superficie de una tela polimérica tridimensionalmacroscopicamenteexpandida a un a superficie de la tela no tejida perforada para formar la tela compuesta laminada.A laminated composite fabric (70) suitable for use as a top sheet (38) for an absorbent article (20). The fabric is a laminate of two liquid-permeable materials, the first of which is a hydrophobic perforated non-woven fabric (210) with an effective area provided with openings (204) with an effective size while the second material is a macroscopically formed film expandable (250) with an effective open area. The film formed is provided with capillaries (241) defined by interconnected side wall portions. The effective size of the capillaries is such that each opening of the noted fabric circumscribes a portion of at least two or more capillaries. Preferably, the outer surface of the nonwoven material is treated with a surface treatment with a surface energy less than the surface energy of the nonwoven material. Also, absorbent articles use the laminated fabric as a top sheet and a method for manufacturing the laminated fabric in which a plurality of weakened places stabilized by fusion are then broken up, creating a plurality of nonwoven openings in the fabric, and a surface is joined of a three dimensional macroscopically expanded polymeric fabric to a surface of the perforated nonwoven fabric to form the laminated composite fabric.
