Theoretical Analyses of the 1X1 Rib Knitting Behavior

Abstract

The computer program based on our mathematical model of the 1X1rib knitting process can predicted the stitch length and the course length, the yarn tensions in the 1X1 rib knitting zone, the robbing back length on the course or the stitch, RB%, the maximum yarn tension value and position. The effects of the depth of stitch draw, the cam angle, the step length of cam and the input tension on the course length or the stitch length, the yarn tensions in the 1X1 rib knitting zone, the robbing back length on the course or the stitch, RB%, 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 depth of stitch draw, the cam angle and the step length of cam, but decreases with the increase of the input tension. 2) The robbing back length and RB% increase with the increase of the depth of stitch draw and the input tension, but decreases with the increase of the cam angle and the step length of cam. 3) The maximum tension increases with the increase of the depth of stitch draw, the step length of cam and the input tension, but decreases with the increase of the cam angle.
