Abstract

Delignification effect of bleaching reagents for pulp samples (sulfate hardwood and softwood, as well as sulfite softwood pulp) is shown to be higher according to IR-Furje spectroscopy data than according to data obtained by Kappa number method. It speaks about the presence of structural fragments in the treated fiber able to react with potassium permanganate alongside with lignin. Method of assessing input of such reactive structures in the value of Kappa number is proposed. The versatility of the influence of CE, DE and P stages on all three types of semi-finished products and dependence of the influence character of O and ZE stages on pulp type are revealed.
