Abstract
The invention relates to a method for producing microscale and/or nanoscale fiber material. The method has at least the step of dispersing (5) dried pre-comminuted pump in a liquid. The method additionally has a step of finely comminuting (6) the pulp dispersed in the liquid such that a fine comminution mixture is produced which contains the liquid and the fiber material with the microscale and/or nanoscale fibril agglomerates.
Claims18
A method for producing microscale and/or nanoscale fiber material, comprising at least the following method steps:
- mechanically pre-comminuting pulp substantially without addition of a liquid, in order that the average fiber length of the pulp comes to lie within the range of 0.025 mm-6 mm;
- dispersing the dry, mechanically pre-comminuted pulp in a liquid;
- and
- finely comminuting the pulp dispersed in the liquid such that a fine-comminution mixture is formed, which contains the liquid and also the fiber material containing microscale and/or nanoscale fibril agglomerates.
A material comprising fiber material containing microscale and/or nanoscale fibril agglomerates, the fiber material having been produced by a method comprising at least the following method steps:
- mechanically pre-comminuting pulp substantially without addition of a liquid, in order that the average fiber length of the pulp comes to lie within the range of 0.025 mm-6 mm;
- dispersing the dry, mechanically pre-comminuted pulp in a liquid;
- and
- finely comminuting the pulp dispersed in the liquid such that a fine-comminution mixture is formed, which contains the liquid and also the fiber material containing microscale and/or nanoscale fibril agglomerates.
