Bending vibrational properties of silk fabrics were measured in details and analyzed by using the new mechanical parameters of bending vibration. It was shown that bending vibration of Georgette continued the longest and that those of Chirimen and Shantung shorter within the six silk fabric groups. Silk fabrics are classf ied into two groups, that is, one is Habutae, Dechine and Georgette group, which has longer damping of bending vibration of fabrics, and the other is Fujiginu, Chirimen and Shantung group, which is shorter in bending vibration than that of the former. Those features of silk fabrics in bending vibrational properties became more distinct by discriminant analysis using the parameters of bending vibration as variable. These classifications could be explained by the mechanism of the interyarn and/or inter-fiber f rinctional effect during bending vibration of silk fabrics.
