摘　　要：染色是提高竹材装饰性能的重要手段,对提高刨切薄竹的附加值,拓展刨切薄竹的应用范围具有重要的意义。染色工艺是薄竹染色的重要手段,上染率是判断刨切薄竹染色效果的主要指标。本文对染色上染率的工艺参数如染色温度、染色时间、pH值以及染液材积比等进行研究。结果表明,染色温度对刨切薄竹单板上染率的影响极显著,随着温度的升高,上染率增加,90℃时,上染率达到最大值;随着染色时间的延长,刨切薄竹单板上染率逐步增加。0.4 mm厚的刨切薄竹单板在90℃染色30 m in,能达到要求的染色效果;随着材积比的增加,染料吸附量也增加。Dyeing is an important method to improve the decorating performance of wood products.It may not only increase the added value of wood,but also expand the scope of wood application.The dye uptake is one of the most important indexes to judge the effect of dyeing.The technical parameters affecting dye uptake,including dyeing temperature,dyeing time,pH value and volume ratio of liquor to timber etc,were studied.It was shown that dyeing temperature significantly affected the dye-uptake.The dye-uptake increased ...
