苦槠木染色深度影响因素初探

Influencing factors of dyeing depth on Castanopsis sclerophylla

通过多因素正交试验,研究苦槠Castanopsissclerophylla木边材染色深度的影响因素及最佳工艺。结果表明:影响苦槠木边材染色深度的各因素主次顺序为:染液质量浓度>冷热间隔时间>NaCl质量浓度>后处理温度>染色时间。在试验条件下,苦槠木边材染色深度最佳工艺为:不用NaCl溶液前处理,染液质量浓度为15 0g·L-1,将木材交替置于冷热染液中(间隔时间为30min),染色90min。

.The influencing factors and optimal technology of dyeing depth of Castanopsis scterophylla are studied by a series of multi-factor orthogonal experiments.Results show that the importance degrees of the tested factors are as follows:the dyestuff concentration>hot-cold interval>NaCl concentration>the post-treating temperature>dyeing time.And the optimal dyeing technology is as follows:no pretreating with NaCl solution;the dyestuff concentration is 15.0 g·L^(-1);dip the wood in the cold solution and hot solution alternatively(30 min interval),the total dyeing time is 90 minutes.
