Abstract

Un tejido de fibra que comprende: a.) una capa inferior que posee fibras de matriz y fibras termoplásticas; y b.) una capa superior que posee fibras de matriz y fibras termoplásticas; en donde una pluralidad de áreas de partículas funcionales se ubica entre la capa inferior y la superior de modo de entrar en contacto con cada una de dichas capas, y en donde cada una de las áreas de partículas funcionales está separada de las demás áreas de partículas funcionales por un área de sellado que posee un sello formado entre la capa inferior y la superior.1Un artículo absorbente que comprende:a.) Una capa inferior que posee fibras de matriz y fibras termoplásticas;b.) Una capa superior que posee fibras de matriz y fibras termoplásticas;c.) un área de partículas funcionales que se ubica entre la capa inferior y la superior de modo de entrar en contacto con cada una de dichas capas;d.) un área de sellado que posee un sello formado entre lacapa inferior y la superior, la cual se encuentra sustancialmente libre de partículas funcionales.2Un método para fabricar una estructura de fibra unitaria de trazado de aire, el cual comprende:a.) proporcionar una primera capa del tejido de fibra;b.) colocar una pluralidad de partículas funcionales en unahilera en la primera capa;c.) proporcionar una segunda capa del tejido de fibra;d.) colocar dicha segunda capa sobre la primera capa de modo que entre en contacto con la primera capa y con la hilera de partículas;e.) sellar la primera y la segunda capa adyacente a dicha hilera, formando de esta manera una hilera de partículas separada ubicada entre la capa superior y la inferior; yf.) curar dicha estructura absorbente a una temperatura de135 a 165°C.<EMI FILE="00043007_1" ID="1" IMF=JPEG >
