Abstract

The purpose of this study was to minutely inverstigate the recovery of compression set confirmed in the previous paper. After the test specimens of three different wood species were heated in the microwave irradiation, they were compressed in radial direction and were dried under restraint. Then, the amount of recovery of set occurring when the set-woods were subjected to the adsorbed moisuture content and the heating in water were measured. The results obtained were as follows; 1) The set-wood compressed in the radial direction, as show Fig. 1,was obserbed the dimentional enlargement in the direction of its right angle for each wood species. 2) The set-wood recived with the adsorbed water and the heating in water, when the amount of initial set were assumed, take about equal values irrelevant to the amount of set. This will be suggested that the fandamental properties of set take no differ with the amount of the set. 3) The recoveried set per the moisture content 1% increased with increase of the moisture content. 4) The recoveried set per the rise of 1℃ take the maximum value with the one temperature in the range of 20-100℃. The temperature showed the maximum value appear on the high temperature side with the softwood against the hardwood.
