Study on the Dyeing Effects of Thick Birch and Elm Wood Veneer by Atmospheric Pressure Impregnation

Article Preview

Abstract:

The dyeing effects of atmospheric pressure impregnation method on thick Birch and Elm veneer under bleached and unbleached treatment were discussed in this paper, as well as the color changes and influencing factors analyzed by CIE(1976)L*a*b*color system. The results showed that it was feasible to dye the thick Birch veneer using red acid GR under unbleached treatment and both the color saturation and gloss met the requirements while disperse dyes were not suitable for the thick veneer because of the general results, poor penetration, and low uptake rate. The dyeing effect on Elm was not satisfactory so that it was not recommended as dyeing wood while its better material quality made it better for furniture.
