Abstract
La presente invención se relaciona con un método de producir pasta para disolver, caracterizado porque se utiliza como materia prima la pasta de papel blanqueada producida por medio del proceso de fabricación de pasta kraft. El método se lleva a cabo por medio del tratamiento alcalino en frío, mezclando la pasta de materia prima con una solución alcalina concentrada, de modo tal que la mezcla de la pasta y la solución alcalina contenga de 50 a 2 0 g/1 de álcali, y dejando que la pasta absorba la solución a una temperatura de 20 a 50 °C.
