(Faculty of Technology, Tokyo Metropolitan University, Fukazawa-Cho, Setagaya-Ku, Tokyo) Angora rabbit fibres were immersed in a solution containing Hg(NO3)2 (1.8%) and HNO3 (3.6%) at 30°C for 30min. After being squeezed they were dried at 95°C for 30min. and aged for 3_??_12 months at 35±1°C, during which the change in their mechanical properties was traced and the following results were obtained:
(1) The mechanical properties changed when the aging period became more than three months but the change after 3_??_12 months was statistically negligible.
(2) When the carroted fibres were aged after being washed, the aging effect can not be recognized.
