摘　　要：主要研究了TMP制浆中经筛分处理和打浆后纤维的变化。先进行筛分处理,然后对长纤维组分进行先低浓打浆(LCR)后高浓打浆(HCR)相结合,并且调整低浓打浆占比。打浆浓度和纤维长度分级(以及对长纤维组分打浆)导致纤维性能发生重要变化。因为仅是纤维粗度的降低并不能解释观察到的结合强度的改善。由于纤维表面分层很少,所以观察结果表明,观察到的抗张强度指数的改善最有可能是由于纤维本身的微观结构的变化(如纤维壁上的裂纹或内部分层)。这些微结构变化增加了纤维的柔韧性,改善了纤维的结合面积。The primary aim was to study a variation in TMP manufacture,in which an interstage fractionation followed by low consistency refining( LCR) and high consistency refining( HCR) in series for different percentage of LCR,is applied to the long fibre fraction. Both consistency of refining and fractionation( together with refining of the LF fraction) lead to important differences in terms of fibre development. The decreases in coarseness alone cannot explain the bonding improvement observed. As little delaminated surface is believed to be available,this observation suggests that observed improvements in the tensile index,are most probably due to the changes in the microstructure of the fibre itself( such as cracks in the wall or internal delamination). These microstructure changes increase fibre flexibility and therefore develop the bonding area.
