Abstract

SE PRESENTAN ARTICULOS ABSORBENTES TALES COMO PAÑALES, ARTICULOS PARA LA INCONTINENCIA, COMPRESAS SANITARIAS Y SIMILARES. MAS PARTICULARMENTE, SE PRESENTA UNA LAMINA DE CUBIERTA PARA ARTICULOS ABSORBENTES QUE TIENE UN TEJIDO NO ENTRETEJIDO Y UNA PELICULA TERMOPLASTICA APERTURADA Y PROCEDIMIENTOS PARA LAMINAR VARIAS CAPAS, AL MENOS UNA DE LAS CUALES ES UNA PELICULA TERMOPLASTICA Y OTRA ES UN TEJIDO NO ENTRETEJIDO. LA PELICULA TERMOPLASTICA APERTURADA COMPRENDE ENTRE UN 0% Y UN 30% DE POLIPROPILENO Y ENTRE UN 70% Y UN 100% DE POLIETILENO, Y EL TEJIDO NO ENTRETEJIDO COMPRENDE AL MENOS POLIPROPILENO. EL TEJIDO NO ENTRETEJIDO Y LA PELICULA TERMOPLASTICA APERTURADA SE UNEN AL MENOS MEDIANTE LA APLICACION DE PRESION. PUEDE CONSEGUIRSE UNA UNION FUERTE ENTRE LAS CAPAS A CAUSA DE QUE ESTAS CONTIENEN EL MISMO COMPONENTE QUIMICO DE POLIPROPILENO, MIENTRAS QUE LA FABRICACION DE LA PELICULA ES MAS FACIL REQUIRIENDOSE UNA TEMPERATURA Y UN VACIO MENORES, QUE SI CONSTASE SOLAMENTE DE POLIPROPILENO.
