Abstract
A method of extracting natural fibres from a fibre feedstock, the fibre feedstock comprising gum between the natural fibres. Fibre feedstock is introduced into water with a first oxidizing agent. The first oxidizing agent partially reacts with the gum. The oxidizing agent is modified, such as by introducing a second oxidizing agent or reducing the concentration of the first oxidizing agent, and reacts with the partially reacted gum. The released fibres are then removed from the water.
