In this paper, konjac glucomannan was cationized by 3-chloro-2-hydroxypropyl trimethyl ammoniumchloride (a kind of cationic reagent) as a paper strength agent. The effects of dosage of cationic reagent, cationization time, cationization temperature and the pH of papermaking on paper properties were analyzed. The results showed that when 1% cationic glucomannan (the cationization temperature was 70 degrees C, dosage of cationic reagent was 20% and cationization time was 5 h) was added, tensile index, burst index and folding endurance of the paper were improved by 11.0%, 13.2%, 72.0%, respectively, compared with the control. The results of SEM analysis, FTIR analysis, and elemental analysis illustrated that the addition of paper strengthening agentmake fibers combined more closely, and further lead to the increase of paper strength properties.
