Abstract
The computer program based on our mathematical model of the plain knitting process can predicted the loop length and the course length, the yarn tensions in the plain knitting zone, the robbing back length on the course, the robbing back rate, the maximum yarn tension value and position. The effects of the frictional coefficient of yarn/knitting elements on the course length, the yarn tensions in the plain knitting zone, the robbing back length on the course, the robbing back rate, the maximum yarn tension value and position are analyzed theoretical. The results obtained are as follows. 1) The course length increases with the increase of the frictional coefficient. 2) The robbing back length and the robbing back rate decrease with the increase of the frictional coefficient. 3) The maximum tension value increases with the increase of the frictional coefficient.
