经编闪避垫纱提花织物的计算机仿真

Computer simulation of warp knitted dodge lap jacquard fabric

为满足经编闪避垫纱提花织物开发设计阶段预测花纹形状的仿真需求,在研究经编闪避垫纱提花织物的提花原理及外观特征基础上,根据花梳的组织结构对其进行分类;同时,为该经编提花织物建立了通用的穿经、垫纱数码、梳栉意匠图及织物意匠图等数学模型,并对不同类型的经编闪避垫纱提花织物分别进行了数学描述和类型判断,分析了平布类和起绒类经编闪避垫纱提花织物的意匠图矩阵赋值方法。利用VC++.NET程序语言作为软件开发工具,结合仿真原理,实现了经编闪避垫纱提花织物的仿真,并以经编闪避垫纱提花绒织物的仿真为例进行验证,结果表明该仿真方法有效。

To meet the simulation need of warp knitted dodge lap jacquard fabric for forecasting pattern shape in the stage of development design,some researches are made. On the basic research of jacquard method and appearance features of warp knitted dodge lap fabric,general mathematics models like drawing-in,lapping,guide bar pattern grid and fabric pattern grid for the fabric were established according to different structures. Then,different types of warp knitted dodge lap jacquard fabric were subjected to mathematics description and judge,respectively,jacquard graph matrix assigned value methods of warp knitted dodge lap plain fabric and brushed fabric were analyzed. Combining the jacquard graph matrix assigned value,VC ＋ ＋. NET programming language was implemented as a software development tool to realize the simulation of warp knitted dodge lap jacquard fabric. Finally,a warp knitted dodge lap jacquard pile fabric was used as an example to verify the availability of the simulation.
