摘　　要：为对浮纹型贾卡经编针织物的外观效果进行预测,通过分析浮纹型贾卡经编针织物的结构特征,提出采用设计意匠图和WB意匠图相结合的意匠设计模型对该类织物进行设计与仿真,并在此基础上建立线圈结构模型,确定线圈中控制点的数目和位置并以线段方式来描绘线圈形态。重点对浮纹织物中因衬纬贾卡和压纱贾卡纱线张力导致的线圈横向位移做了理论分析,并对不同张力下衬纬贾卡和压纱贾卡的线圈形态做了详细的数学描述。运用上述意匠设计模型、线圈结构模型和横向位移规律,采用VC++.net进行程序设计,成功实现对浮纹型贾卡经编针织物的直观、快速仿真。In order to predict the appearance effect of warp knitted broché fabric,after studying the structure of warp knitted broché fabric,the design and simulation of this fabric was proposed using pattern notion in conjunction with WB pattern notion.The loop structure model was set up to confirm the number and position of control points and segment was used to describe the loop state.The article made a theoretical analysis on the horizontal displacement of loop resulting from inlay jacquard and fall-plate jacquard.A detailed description of lapping movements of guide bars from inlay jacquard to fall-plate jacquard was made.Based on the pattern notion design model,loop structure model and the rule of transverse movement,program design was performed using VC ＋ ＋.net,and the visual and quick simulation of warp knitted broché fabric was realized.
