In this study, ethylated wood powder/polystyrene plastic composite (WPC) was obtained by combining ethylated Chinese Fir powder with polystyrene foam in DMF or CHCl3, and was dyed with disperse dyes. The results show that the compatibility of ethylated fir powder with polystyrene was good when the ratio of wood to plastic ratio is beyond 3:1. The color shade of dyed wood-plastic powder is close to that of dyed polyester fabric and high temperature is favorable for the dyeing of wood-plastic powder. Moreover, dyed wood plastic powder has good wa...
