Method of separating colouring agents, particularly printing ink, from recycled fibre material |
摘要 |
A method of separating colouring agents, particularly printing ink, from recycled fibre material, in which method the recycled fibre material is defibered using a liquid, so that colouring agent is separated from the recycled fibre during the defibration. In the method, the pre-kneaded recycled fibre is applied to a double-action impact mill, where it is subjected to successive impacts, so that the treatment time is at most some seconds.
