Abstract Chinese fir was compressed by vacuum hot pressing and conventional
hot pressing at different temperatures (180°C, 200°C and 220°C), respectively.
The color parameters of the heat-compressed sample were measured, the relative
mechanical properties of the material were tested and changes in the chemistry of
fir were investigated using Fourier transform infrared spectroscopy (FTIR) and Xray photoelectron spectroscopy (XPS). The results indicated that the color difference between compressed and untreated wood increased gradually with the
increase of temperature. Compared with the conventional hot pressing treatment,
the color difference (ΔE*) of the Chinese fir treated by vacuum More >
