The invention concerns a process for the production of activated fibres or particles having self-binding properties comprising the steps of treating fibres or particles of lignocellulose containing material by contacting them with an oxidant during a time sufficient for the formation of water soluble reaction products with binding properties and retaining at least a significant part of said water soluble reaction products with the treated fibres or particles. The invention further concerns activated fibres or particles obtainable by the process, a press moulded product and a process for the production thereof from activated fibres or particles.
