Water sorption studies in different varieties of furniture wood

Water sorption studies have been carried out on four varieties of wood i.e. Tahli, Sagwan, Safeda and Champ. In Water sorption studies wetting- drying cycles as well as wetting processes have been studied upto fourth cycle in fore mentioned varieties. The wetting - drying cycles showed continuous decrease in hysteresis areas for Sagwan and Champ wood, whereas no significant change was observed in hysteresis areas for Tahli and Safeda wood. This consistency was also observed in wetting processes. The slopes for wetting process showed continuous decrease for Sagwan and Champ wood, while for Tahli and Safeda wood slopes were constant upto fourth cycle. The wetting processes were excellently represented by quadratic relations; with coefficients being significant at 1% level of significance. The R² value between fitted and observed data was in the range of 0.92 to 0.98 in respect of all the cases studied.
