Abstract

Lignocellulosic material of sheet structure and a dry solids content > 80 %, preferably > 85 %. The material is characterized by a density which lies within the range of 400-575 kg/m<3> measured in accordance with the standard method SCAN-P7:75 and a disintegration ability calculated as the amount of electrical energy consumed during disintegration of the material in a hammer mill of between 30 and 60 kWh/ton pulp, preferably 35-50 kWh/ton pulp, and in that subsequent to being disintegrated the material has a bulk density of 15-23 cm<3>/g measured in accordance with the standard method SCAN-C33:80 and a network strength of 2-4.5 N. The invention also relates to a method for producing a continuously wet-formed web of lignocellulosic material, comprising the steps of dewatering and pressing the web to a dry solids content of about 30-60 %, followed by drying the web. The method is characterized by compressing the wet formed web having a dry solids content of at least 50 %, preferably at least 80 % with a linear pressure resulting in a density increase of more than 10 %.
