The present invention relates to reinforcing and/or process fibres based on vegetable fibres whose elementary fibres are fibrillated and to a process for their production. The reinforcing and/or process fibres are characterized in that the elementary fibres have a fibril content greater than 3 area percent and less than 50 area percent. The process is characterized in that the fibre material is ground in an eddied air grinder.
