Abstract

The mechanical properties of deinked mixed office waste paper in relation to sorts and dosage of enzymes were investigated for successful enzymatic deinking of mixed office waste paper. The increasing of $\Delta$. freeness was most predominant in pulp of Denimax treated pulp. The tensile and burst properties are decreased with enzyme dosage while $\Delta$. freeness were increased. The fine content in disintegrated pulp was decreased with enzyme dosage of $0.4\%$ on the dried weight of paper. The water absorption of handsheets of enzyme deinked pulp was like as that of market roll tissue papers and the mechanical properties of handsheets of enzyme deinked pulp were improved with enzyme treatment comparing of market roll tissue papers.
