Abstract

EL PRESENTE INVENTO SE REFIERE A UN METODO PARA CARGAR UN COMPUESTO QUIMICO DENTRO DE LAS FIBRAS DE UN METAL FIBROSO, Y A LOS MATERIALES FIBROSOS PRODUCIDOS POR EL METODO. EN EL METODO, SE PROPORCIONA UN MATERIAL CELULOSO FIBROSO, QUE CONSISTE DE UNA PLURALIDAD DE FIBRAS ALARGADAS CON UNA PARED DE FIBRA QUE ENVUELVE UN INTERIOR HUECO. EL MATERIAL FIBROSO TIENE UN CONTENIDO DE HUMEDAD TAL QUE EL NIVEL DE AGUA VARIA ENTRE 40 AL 95% DEL PESO DEL MATERIAL FIBROSO, Y EL AGUA SE ENCUENTRA POSICIONADA SUSTANCIALMENTE DENTRO DEL INTERIOR HUECO DE LAS FIBRAS Y DENTRO DE LAS PAREDES DE FIBRA DE LAS MISMAS. SE AÑADE UN PRODUCTO QUIMICO AL MATERIAL FIBROSO DE TAL MANERA QUE EL PRODUCTO QUIMICO SE DISPONE EN EL AGUA PRESENTE EN EL MATERIAL FIBROSO. EL MATERIAL FIBROSO ENTRA ENTONCES EN CONTACTO CON UN GAS REACTIVO CON EL PRODUCTO QUIMICO, PARA FORMAR UN COMPUESTO QUIMICO INSOLUBLE EN AGUA. EL METODO PROPORCIONA UN MATERIAL FIBROSO CON UN COMPUESTO QUIMICO CARGADO DENTRO DE LOS INTERIORES HUECOS Y DE LASPAREDES DE FIBRA DE LA PLURALIDAD DE FIBRAS.
