Abstract
La presente invención se refiere a un método para tratar las materias primas lignocelulósicas que contienen pectina en un proceso de reducción a pulpa de alto rendimiento que utiliza una o más etapas del tratamiento bajo condiciones alcalinas. La invención proporciona un método para controlar la etapa de tratamiento, en donde el álcali es aplicado en una etapa del tratamiento a baja temperatura antes de una o más etapas consecutivas de tratamiento a la misma o a una temperatura mayor. La presente invención también provee la pulpa, el papel, el cartón o el tejido obtenidos mediante ese método.
