摘　　要：针对贾卡经编针织物的结构特征,提出这类织物的意匠设计模型,在此基础上对这类织物的线圈结构进行分析。以成圈结构为例建立贾卡织物的理论线圈结构模型,确定线圈中控制点的数目和位置,并分情况以线段和样条曲线2种方式来描绘线圈形态。重点对贾卡织物中线圈的位移和形变作了理论分析,并提出完善的实际线圈结构模型。仿真过程不但要考虑意匠信息、梳栉垫纱规律等引起的纱线张力变化,还要全面考虑纱线粗细、颜色和材质等,仿真效果较好。The characteristics of jacquard warp knitted fabric were studied and the colorized design model was offered. The loop structure of the fabric was analyzed and its theoretical model was set up to confirm the number and position of control points of each type of loops. Two methods, i.e., segment and spline cure were used to describe the loop state with focus on theoretical analysis. In order to show of displacement and distortion of loop, presenting a factual model of the loop. In simulation, considerations were given to information concerning the colorized design, the change of yarn tension resulting from lapping movement, fineness of yarn, color information, and the quality of material. Thus a good simulation was achieved.
