Abstract

The repeated wetting and drying of a recycling process affects the strengths of papers from recycled pulps, as well as the micro-structure of the pulp fibres. Relationships between pulp fibre and handsheet properties during recycling were assessed by using thirty-three individual trees of Eucalyptus globulus. The shrinkage of internal pore structure under recycling was not easily reversed. The lumen diameter:fibre width ratio well reflected the shrinkage configuration of Eucalyptus globulus pulp fibres during recycling, and the high correlation with handsheet strength properties such as tensile and tear could be expected. The Eucalyptus globulus pulps with a significant decrease in handsheet tensile strength during recycling are prone to swell less, as shown in the water retention value, and reduce their bonding potential.
