Abstract
Dyeing of veneer is an important value-adding process, particularly for young plantation hardwood species, which often have uneven colour and “dull appearance”. An important indicator in the assessment of the performance of veneer dyeing process is the dye uptake. This study compared two different methods of measuring dye uptake of dyed veneers; by using either liquid uptake based method or spectrophotometry method. The study revealed that there was a significant difference in the percentage of dye uptake determined by the two methods, but the overall results in the correlation between the percentage of dye uptake and the dyeing parameters had a similar trend.
