The paper deals with the variation of the kappa number, lignin and hexenuronic acid content of the washed and unwashed spruce kraft pulp. The displacement washing was carried out with the spruce kraft pulp having seven level kappa number. It was notice able that the depletion of lignin content after washing depend supon the kappa number of the pulp. The most variation was found in the Klason lignin content of the pulp. The leaching of lignin was least for the pulp with the lowest kappa number. Hexenuronic acid composition of the unwashed pulp was hardly affected by the displacement washing.

PL

W artykule opisano wahania liczby kappa, zawartości ligniny i kwasu heksenuronowego przed i po myciu masy siarczanowej z drewna świerkowego. Mycie wyporowe zastosowano do masy siarczanowej świerkowej o siedmiu poziomach liczby kappa. Zaobserwowano, że spadek zawartości ligniny po myciu zależy od liczby kappa masy. Największe zmiany zaobserwowano w przypadku zawartości w masie ligniny Klasona. Wymywanie ligniny było najmniejsze w przypadku maso najniższej liczbie kappa. Mycie wyporowe miało znaczący wpływ na skład kwasu heksenuronowego w mytej masie.
