文摘内容 Fiber screen analysis, fiber quality analysis and SEMobservation were used to investigate the effects ofNaOH charge on fiber characteristics in TriploidPopulus Tomentosa P-RC APMP pulping in thispaper. The results showed that increasing NaOHcharge in P-RC APMP process could reduce energyconsumption and fines percent, increase the meanfiber length and long fiber percent and make the curlindex and kink index of fiber ascend. The resultsfrom SEM observation illustrated that the fiber withhigh NaOH charge had higher softness degree, bettercutting resistant ability and better inter-fiber bondingability. With increasing of NaOH charge, the surfaceof handsheets became more and more smooth, andthere were less and less gaps and holes on the papersurface。
