Studies on the Dye-Uptake of Fraxinus Mandshurica Veneer with Reactive Dyes

In order to explore the factors of fraxinus mandshurica veneer dye-uptake, the discourse made use of reactive dyes. The result showed that significant effects of fraxinus mandshurica veneer dye uptake are reactive dye concentration, dyeing temperature, dyeing time and sodium chloride concentration. The artificial dyeing technology of fraxinus mandshurica was defined finally. Using reactive dyes, reactive red X-3B 10 g/L, temperature 95 °C, the dyeing time 240 min, sodium chloride 30 g/L. The study provided a theory gist and a practical guidance role for imitation precious wood.
