The present invention relates to a process for the production of treated pulp comprising the steps of: i. providing a fibre source material; ii. subjecting the fibre source material to pre-hydrolysis; iii. subjecting the pre-hydrolysed fibre source material to alkaline chemical pulping process, preferably kraft pulping, to obtain an alkaline pulp; iv. optionally adjusting the pH of the obtained pulp to above pH 9; v. subjecting the alkaline pulp to a bleaching sequence comprising contacting the pulp with ozone (Z) in alkaline conditions to obtain a treated pulp. The invention also relates to a treated pulp obtained, textile fibres produced from the treated pulp, textile products comprising the textile fibres and to the use of the treated pulp.
