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 SE PREPARA SOMETIENDO UNA SUSPENSION DE PASTA MICROFIBRILADA A GENERACION DE POROS MEDIANTE CONGELACION E INTERCAMBIO CON DISOLVENTE Y A ENTRECRUZAMIENTO CON UN AGENTE ENTRECRUZANTE. 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.
