AbstractFine paper consumption in Asia is growing rapidly, however this region is a net importer of short-fiber pulp. The commonly used raw material for fine paper is mixed-tropical hardwoods (MTH) which come from the forest, comprises of various wood species, and consequently, it has non-uniform properties. There are two promising new sources of short fiber, i.e. acacia and eucalyptus that grow in plantation, having more uniform properties than MTH, and excellent light-scattering ability due their high number of fibers per unit weight, however their bonding ability is lower than MTH. In this study, Acacia mangium and mixed tropical hardwoods pulps from Indonesia were compared to Eucalyptus camaldulensis pulp from Thailand, to obtain the paper technological potential of those pulps for fine paper, especially copy paper. The result is that acacia was proved superior in light-scattering ability and smoothness, higher filler-carrying ability and lower dusting propensity. The drawbacks are acacia's low bonding ability and low porosity. Eucalyptus is morphologically close to acacia, but most of its properties fall between acacia and MTH, while MTH has excellent bonding ability but poor opacity.
