摘要
纬编双面移圈产品工艺复杂,设计难度大,针对现有纬编双面移圈产品设计繁复的问题,研究并开发了纬编双面移圈产品设计系统。首先分析了纬编双面移圈产品结构成形原理和工艺设计,采用数学矩阵与多维工艺分解方法描述了移圈花型与工艺结构的数学关系:花型意匠图描述移圈花型图案信息,编织意匠图描述纱线系统和移圈动作信息,结构分解图说明花型行与工艺行的关系,工艺编织图表示纱线的编织状态。建立的纬编双面移圈产品工艺设计模型具有较高的实用性,简化了纬编双面移圈产品工艺设计流程,规范了设计方法,实现了纬编双面移圈产品的快速高效开发。
Objective Weft-knitted two-side transfer fabrics are regarded as complicated in technology and difficult in design.In order to achieve rapid design of weft-knitted two-side transfer fabrics,this paper studies and develops the weft-knitted two-side transfer fabric design system aiming to tackle the complicated design of weft-knitted two-side transfer fabrics.Method The structure forming principle of weft-knitted two-side transfer fabric was analyzed,and the process design model of weft-knitted two-side transfer fabrics was established.The mathematical relationship between transfer pattern and process structure was described by using mathematical matrix and multi-dimensional process decomposition method.The multi-dimensional technological decomposition of the pattern effect was achieved on a graph,and the three-dimensional mathematical matrix was used to represent the artistic information for pattern grid and knitting pattern grid to assist the structural decomposition and the knit process.The pattern design process was simplified by means of algorithm and primitive mapping.Results The schematic diagram of the established process design model was shown in the weft-knitted two-side transfer fabric with two jacquard and two loop shifting(Fig.1).The process design model of the weft-knitted two-side transfer fabric involves multi-dimensional information.The pattern effect picture was divided into the front pattern and the reverse pattern and the two sides of the fabric were divided into the front and the reverse pattern.The three-dimensional matrix was used to describe the information.The color information in the cell was stored as the corresponding three-dimensional data.The fabric pattern was woven by A/B yarn system and two loop shifting systems,and the knitting design of yarn A,yarn B,needle cylinder loop shifting and needle disk loop shifting were established respectively.The corresponding color,position information ck,tk,flower width w,flower height h,and process flower height H were obtained.The structural break
