The five - stage bleaching sequence, Q 1 Q 2 EP PaaP, containing two chelation stages, as well as four - stage sequence, AEP PaaP, with an acidic stage were applied to investigate the properties of bleached soda pulp, namely its brightness and tensile strength. For comp arison, once - dried kraft softwood pulp, as well as never - dried oxygen - predelignified kraft softwood pulp and sulphite spruce pulp were bleached under the same process conditions. The results obtained showed that totally chlorine - free bleaching did not brin g the sufficient bleaching effect for soda rapeseed pulp. The brightness of 54 % ISO achieved for the AEP PaaP bleaching sequence was lower comparing to that for kraft and sulphite pulps.
