Nd-s蚕繊維のX線回折図形

抄録

The purpose of this paper is to get an X-ray diffraction pattern of the fiber (about 100% sericin) of Nd-s silkworm without influence of the crystallization of sericin by water during the spinning. From the silkworm, a fiber was spun at 25°C and a velocity of the wind 20-50cm/sec and in the atmosphere of 35, 50, 65 and 85% relative humidity (R. H.). X-ray diffraction pattern of the fibers was measured to find out a R. H. range for the spinning without crystallization. The X-ray diffraction pattern of the fibers spun in the atmosphere of 35 and 50% R. H. showed an oriented amorphous structure. In case of the 65 and 85% R. H., the crystallization of the silk fiber occurred. The results indicate that the amorphous structure of the silk fiber spun in the atmosphere below 50% R. H. is maintained without being affected by water.
