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 l_v and ι_n can be described as follows : ι_v-Hanging Length of Vertical Direction………1.775 magnifications=+77.5% ι_n-Hanging Length of Horizontal Direction……1.860 magnifications=+86% as the test piece used : Synthetic Resin-eighteen different sorts including polymerization, copolymerization, condensed and cocondensed resin. (urea, melamine, formalin, polyvinylalcohol, silicone, styrene, polyvinylchloride, polyvinylidenchloride, acrylic acid ester and acrylic acid amide base resin.) Test Cloth-"2015 numbers of warp yarn per width of fabric" Cotton Broad Cloth.
