Abstract

The invention relates to a method of steaming lignocellulosic material to be pulped. The material is treated in a superheated steam atmosphere. The treatment can be used for loosening up the structure of fibre for mechanical pulping and/or for facilitating the absorption of delignifying chemicals into the fibre.
