The results of rolling were presented in Table 2. From Table 2, it can be mentioned that, Elongation was reduced when speed of the silk was increased. At speed of 6.3 meters per minute, all type of twisting had largest size. For tension testing, to obtain the maximum tension in floss, floss twisted in single line should be roll at speed 6.3 meters per minute, in the same time, floss which twisted in double and triple lines must simultaneously roll at 12.5 meters per minute. By analysis of the
