Dyeing Properties of Cyanoethylated Wood with Disperse Dyes

The color cyanoethylated wood were preparated by means of dyeing under high temperature and pressure. The results indicates that the percentage of dye exhaustion (%E) on cyanoethylated fir powder is 95.3~98.8%. The color shade of dyed modified wood is similar to that of dyed polyester fabric. Compared with the dyed polyester fabric, the color difference (∆E) of dyed modified wood is smaller than that of dyed unmodified wood under the same dyeing condition. Unmodified fir powder, cyanoethylated fir powder and dyed cyanoethylated fir powder were characterized by Fouriertrans- form infrared (FT-IR), scanning electron microscopy (SEM).
