Abstract: To improve the strength and decoration performance of inferior Plectocomia pierreana cane, the strengthening-dyeing modifications were applied using vacuum pressure impregnation with the mixture of acid dye, reactive dye, basic dye and direct dye with melamine-urea-formaldehyde resin(MUF), respectively. The color and strength of the modified canes were than determined. Results showed that the acid dye compound with MUF resin had the optimum dyeing effect; the dye exerted little influence on the strengthening effect of resin modification. After modification, the increase of density, MOE and MOR of the cane lied in the range of 67.91%-73.02%, 56.01%-57.59% and 47.41%-49.69%, respectively. The increase of the compressive modulus and strength of the cane exceeded 50%. FTIR spectrum showed that the dye reacted with MUF resin, forming sulphonate, and then solidified inside the cane, instead of reaction with the cane composition directly. The modified cane exhibited higher density and strength, better decoration performance, and could be exploited for commercial utilization.
