The acetylation of papermaking pulp fiber(SwBKP, SwUKP, HwBKP and HwBCTMF) is carried out to modify the characteristics of pulp and paper. The effects of the addition of acetylated pulp on the filler retention and paper properties were investigated. The acetylation depended upon pulp type and the content of short fiber and fines. The addition of acetylated SwBKP did not deteriorate the retention of clay, talc and calcium carbonate, while the retention of titanium dioxide was increased with the addition of 20% and above. The brightness opacity, air permeability and tear strength were improved, but water resistance, burst strength and folding endurance were decreased by the addition of acetylated SwBKP and SwUKP. The tensile strength of SwBKP was increased until 20% of acetylated pulp is added, and then decreased. The tensile strength of SwUKP, however, was not changed until the acetylated pulp of 25% is added. The dimensional stability was improved by the addition of acetylated pulp and showed the different response to SwBKP and SwUKP.
