The effects of white ledger CNF addition on the drainage characteristics and paper properties were investigated in order to evaluate the possibility of white ledger CNF as a papermaking additive for improving paper properties. The white ledger CNF addition showed a tendency to delay the dewatering on the paper machine wire and did not show any difference from the HwBKP CNF. As a result of FAP (Final Air Permeability) measurement to predict the dewatering characteristic at the press part, the FAP value tended to be slightly increased by the addition of CNF, but the difference was not so large enough that the dewatering at press part would not be significantly deteriorated. The bulk was slightly decreased as white ledger CNF was added, but there was no difference according to the kind of raw materials used for CNF production. The air resistance was increased with the increase of white ledger CNF addition. The opacity of handsheet did not show a significant change even though white ledger CNF was added up to 2%. Tensile index, tear index and Taber stiffness of handsheet were all improved by white ledger CNF addition. Especially, tensile index was improved significantly by the addition of white ledger CNF addition. It was also confirmed that alkaline pretreatment of white ledger before grinding is not necessary when it is used as a papermaking additive.
