The purpose of the experiment in this report is to obtain the better form by comparing the theoretical equation on the bending moment of textile fabric in Report 2 (Kaseigaku-kiyo, No.3,1963,pp. 17-24) : C=0.1337 L (cosθ/tanθ) 1/3+0.2970ι_n(tan^<-1>θ) 1/6 with that in report 4 (Kaseigaku-kiyo, No. 4,1964,pp. 17-26) : C=0.1337 L (cosθ/tanθ) 1/3+(ι_n^2-1)[cos^2θ{2.1-0.28(cosθ/tanθ)1/3}] It has been proved through the present experiment that the equation in Report 4 is of more practical value than that in Report 2 with regard to sensitivity, that is, the degree of effect of hanging length of vertical and horizontal directions exerted on the bending moment. The relative degree of sensitivity in connection with ι_v and ι_n can be described as follows : ι_v-Hanging Length of Vertical Direction……1.860 magnifications=+86% ι_n-Hanging Length of Horizontal Direction……1.749 magnifications=+74.9% as the test piece used : Starch-eight different sorts including soluble farinas and synthetic starches.
