Abstract

Chemical additives are usually used in papermaking industry as an effective way to enhance
the strength of paper. However, the researches indicate that their effectiveness depends on
dosage rate and application of them is associated with some problems. Recently utilization of
cationised fiber has been suggested as a solution. Therefore in this study, the effects of
cationised fiber have been evaluated as strength additive. Long fibers of softwoods by the use
of cationic agent EPTMAC at 5, 10 and 15% were cationised and added to the CMP on levels
1, 3 and 5%. Finally, tensile, burst and tear strength of hand sheets were evaluated. The results
showed that with increasing cationised long fiber levels, the strength of CMP will enhance
too. Long fibers cationised at 10% also brought about highest strength.
