Corelation of Colorimetric Parameters with Collapse-Shrinkage Properties in Plantation-Grown Eucalyptus Based on Eco-Furniture Materials

Abstract:

In order to quantify the relationship between collapse-shrinkage properties and colorimetric parameters on plantation-grown eucalyptus as solid-wood furniture, measurements of the above-mentioned indices were carried out on five species of plantation-grown Eucalyptus (Eucalyptus urophylla, E.grandis, E.urophylla×grandis, E.grandis ×urophylla and E.cloeziana) under three kinds of heat-treat patterns(heat, steaming and combination of heat and steaming) and their correlations were investigated by means of regression analysis. Results showed that for the former four low-density prone-collapse eucalypt, collapse-shrinkage properties were strongly correlated with L* and △E*( R2 ≥0.85) under the above treated conditions, while weak linear correlation with a* and b*. For high-density E.cloeziana with extremely lower collapse, the four colorimetric indexes were lightly correlated with collapse-shrinkage properties. Thus, it can be concluded that L* and △Eab* may be regarded as the two primary and more reliable predictors of shrinkage-collapse parameters for low-density collapse-prone eucalypt wood.
