摘要：Dyeing of wood is an important value-adding process. An important indicator in the assessment of the performance of wood dyeing process is the dye penetration. In the present study, the existing method of response surface methodology was extended to study the dyeing process optimization of Ayous (Triplochiton scleroxylon) wood with acid dye using the radial dye penetration percentage as an indicator. The experiments were carried out on the basis of a single factor experiment, and the optimal condition was determined by means of the Box-Behnken Design of response surface methodology. The effects of temperature, dye concentration, dyeing time and accelerant mass fraction on the radial dye penetration percentage of Ayous wood were optimized. The experimental results showed that the maximum radial dye permeability can be achieved under optimum dyeing temperature (86.03 degrees C), dye concentration (0.31%), dyeing time (8 h), and accelerant mass fraction (2.23%). Under these conditions, the maximum dye-uptake and radial dye penetration percentage were found to be 14.28% and 22.34%, respectively. The results of analysis of variance indicated that the mathematical model proposed in this study can be used to predict the dye-uptake and radial dye penetration percentage of acid dye on Ayous wood by changing the process parameters.
