A process adn system for retting of plant fibres in a tank comprising the steps of placing crude fibre from scutched plants in a retting bath with a predetermined water / fibre proportion, or steeping ratio; inoculating the retting bath with strains of bacteria; recirculating the retting bath; controlling and keeping at predetermined values at least one of the following parameters: retting bath tempex-ature, pH value, redox value and oxygen content. In the system a tank is provided with means for supporting the immersed fibre; means for recirculating the liquid; means for reading and keeping at predetermined values at least one of the retting liquid parameters consisting of temperature, pH, redox index and oxygen content, and means for blowing air on command into the retting liquid.
