Abstract: There is described a new method for making a fibre mat under the use of plant fibres, preferably from flax and hemp. The fibres are pre-treated and shortened, whereafter they are separated for establishing a fibre mass comprising single fibres with lengths within a desired interval. Hereafter, the fibre mat is produced by a dry-forming process as the fibres are oriented randomly in the fibre mat. The dry-forming process preferably takes place by using a former head which is placed above a vacuum box as the fibres are deposited on a former wire between these two elements. The plate is fixed as inter-fibre bonds are established between the single fibres. The inter-fibre bonds may be established with or without the use of binders. The formed fibre mats will be open and airy, but at the same time sufficiently stable and cohesive for handling. A field of application for the fibre mat will be isolation.
