Abstract
The influence of cationic wheat flours on the properties of suspensions and laboratory handsheets prepared from a mixture of SAQ semichemical pulp and recovered fibres, with and without addition of enzymatically modified sugar beet pulp (EMSBP), was investigated. The main effects of cationic flour and EMSBP are related to the improvement of handsheet strength properties (tensile and burst index, internal bond strength, CMT and bending resistance), which are higher in the case of simultaneous 30 addition of cationic starches and enzymatically modified sugar beet pulp than in the case of separate addition. It was also observed that cationic flours partially compensate the negative influence of the enzymatically modified sugar beet pulp on drainage time and filtrate loading (COD, BOD ), as well as on 5 the bending resistance and air permeability of handsheets.
