1×1ゴム編編成挙動に及ぼす糸と編成要素との摩擦係数の影響についての理論的解析

摘要

著者らは，平編編成過程の相坂の数式モデルとKnaptonの幾何学的モデルに糸の太さと編成要素（シリンダー針とみぞ壁）の太さやオールドループとニユーループとの接触を組み込んだ平編編成過程の数式モデルを提案した.この数式モデルはオールドループとニューループとの接触を無視すれば，11本遅れのレギュラータイミングの1×1ゴム編編成過程のモデルとしても利用できる.%The computer program based on our mathematical model of the 1×1 rib knitting process can predicted the loop length and the course length, the yarn tensions in the 1×1 rib 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 1×1 rib knitting zone, the robbing back length on the course, the robbing back rate, the maximum yarn tension value and position are analyzed theoretical using the cotton yarn and the worsted yarn. The results obtained are as follows.1) The course length increases with the increase of the frictional coefficient yarn/knitting element both the cotton yarn and the worsted yarn. 2) The robbing back length and the robbing back rate decrease with the increase of the frictional coefficient yarn/knitting element both the cotton yarn and the worsted yarn. 3) The maximum tension value increases with the increase of the frictional coefficient yarn/ knitting element both the cotton yarn and the worsted yarn.
