多经多纬纹织CAD简洁设计模式的实现与应用

为优化多经多纬织物的工艺设计,研发并实现了纹织工艺处理的简洁设计模式。简洁设计模式的设计原理是将常规纹织CAD工艺设计纹织组织表中意匠图颜色号与梭号对应的二维关系转化为一维线性关系。在具体的意匠图工艺设计阶段,采用合成组织,由一色对应多个组织简化为一色对1个合成组织,并且引入梭位和空梭概念,在投梭设计上按梭位进行投梭。二重经二重纬加抛花纹织工艺实践表明:运用简洁设计模式,只需设计6个结构简单的合成组织,即可完成原来需要设计的60个简单组织,极大地简化了多经多纬复杂组织的设计过程。

Implementation and application of jacquard weaving CAD software concise design pattern for multi-warp multi-weft fabrics

To optimize the technology design of multi-warp multi-weft fabrics,this paper develops and implements a concise design pattern of jacquard weaving technology processing.The principle of designing the concise design pattern is to transform the two dimensional relationship of jacquard color No.and shuttle No.,which in the figured hook weave table of conventional jacquard weaving CAD technology design,to one dimensional linear relationship.In the practical stage of jacquard technology design,by using synthesized weave,it′s simplified that one color matching multiple weaves to one color matching one synthesized weave.This paper also introduces the concept of shuttle position and empty shuttle,and picks according to the shuttle position in the design of picking.The practice of double-warp double-weft patterned jacquard weaving technology shows:with the concise design pattern,it only needs to design 6 simple structured synthesized weaves,to complete the 60 simple weaves that it originally needs to design.The concise design pattern significantly simplifies the design process of multi-warp multi-weft complex weaves.
