The dyeing properties of benzylated fir powder with six disperse dyes under high temperature and high pressure were investigated. The characterization of the samples was analyzed by fourier transform infrared spectroscopy (FT-IR) and scanning electron micrograph (SEM). The dyeing results indicated that the color shade of dyed modified wood was similar to that of dyed polyester fabric. The color difference (AE) of dyed modified wood was smaller than that of dyed unmodified wood. In addition, the percentage of dyeexhaustion (%E)) of dyed...
