Abstract

|
|
The aim of this treatise was to investigate the effects of ultra-red ray on the ree1ability of the undried and dried cocoons as well as the characteristics of raw silk. The results obtained are as follows: 1. The percentage of raw silk of undried cocoons was higher than that of dried cocoon and control. 2. On irradiation with ultra-red ray, it was found that the strength of raw silk increased to 4.5 g/d, while the elongation of it remarkably decreased. 3. The raw silk irradiated with ultra-red ray appeared to be brown in color.
