Abstract

SE DESCRIBE UN PRODUCTO ABSORBENTE A BASE DE UNA PASTA CELULOSICA RETENTIVA, ABSORBENTE, CAPAZ DE RETENER UNA BUENA ABSORBENCIA INCLUSO DESPUES DE HABER SIDO COMPRIMIDA CONSIDERABLEMENTE. LA PASTA CELULOSICA SE PREPARA MEZCLANDO UNA SUSPENSION DE PASTA MICROFIBRILADA CON UN AGENTE ENTRECRUZANTE, SEGUIDO DE LIOFILIZACION. LA PASTA ASI OBTENIDA CONSTITUYE UN ELEMENTO ABSORBENTE UTIL PARA SU EMPLEO EN PRODUCTOS ABSORBENTES DE FLUIDOS CORPORALES TALES COMO COMPRESAS SANITARIAS, TAMPONES CATAMENIALES, PAÑALES DESECHABLES O APOSITOS PARA HERIDAS.
