Abstract

Process for the manufacture of paper pulp from plants of annual cycle, characterized in that, in addition to the main washing treatment by any of the normal procedures, the raw material is subjected to a complementary operation of degumming by means of a hot liquid, at a temperature below one hundred degrees, containing a soluble barium or strontium compound.
