 note = {本研究はエチルアミンの吸着による木材可塑化の効果を明らかにすると共に, エチルアミンを気散させた後の材質についても検討を加えたものである。すなわち, エチルアミンを種々の時間吸着させられた材について, 吸着量, 曲げ応力緩和および曲げ強度を測定し, 気散後の材については, 気乾時に曲げヤング係数, 曲げ強度を, また吸湿中に水分吸着量, 膨潤量, 曲げヤング係数を測定した。その結果は次のとおりである。1)エチルアミンは木材の可塑化に効果的であった。2)エチルアミン吸着処理によって, 吸着中の材の曲げヤング係数および曲げ強度は低下し, その低下は処理時間の増加とともに大となる。曲げヤング係数の低下は, 繊維に平行方向よりも直角方向に顕著である。3)エチルアミン気散後の材の曲げヤング係数, 曲げ強度は, 未処理材に比して低下し, その低下は処理時間と共に増大するが差程大きいものではない。また処理時間の増加と共に吸湿性も増加し, それに伴って膨潤量および曲げヤング係数の低下率も増大する。, This report is described on the plasticization of wood by ethylamine adsorption. Three type specimens adsorbed the vapor from 70% ethylamine aqueous solution during different treating time shown in Table 1 in the sealed desiccator were subjected to the stress relaxation test in bending and bending strength test (see Fig. 1,2). The constant strain imposed in relaxation test is about 25% of ultimate strain in A and B specimen, and about 10% in C specimen. The results are shown in Fig. 3 and 4. From these results, the ratios of initial maximum curvature of treated specimen possible to be used in bending without failure to one of untreated specimen were calculated and are shown in Table 4. On the other hand, Young's modulus in bending and bending strength measured on ethylamine evaporated specimens treated by the process shown in Table 2 are shown in Fig. 5. Amount of adsorbed water, swelling in tangential direction, percentage of decrease of Young's modulus in bending, of specimens treated as shown in Table 3 were measured, after adsorbed water in the sealed desiccator for 48hrs. The results are shown in Fig. 6. The each value in Fig. 6 is shown as the ratio of value measured on the treated specimen to one of untreated specimen.},
