摘　　要：为能够通过深入研究花型设计、穿纱设计可织性和三维仿真方法来提高多色调线横条纹织物的开发效率,根据调线圆纬机的编织原理和特点构建花型设计模型并生成色纱编织序列模型。计算出各成圈系统所编织的色纱种类并生成导纱模型,依据排纱原则建立了穿纱设计模型。构建了线圈几何模型和平移映射模型,并探究多色调线横条纹织物的三维仿真方法。运用上述数学模型和理论进行程序设计,以11色渐变调线横条纹为例验证其花型设计和穿纱设计在4色调线圆纬机上的编织可行性,并对比织物实物图和三维仿真图。结果表明,设计模型验证方法切实可行,仿真花色效应良好,该方法为多色调线横条纹织物的设计方案可织性分析和织物三维仿真提供了理论参考。Objective Multi-color striped fabrics are one of the important fashion elements in knitwear design.The development of the knitwear fashion trend reveals that fabrics with a small number of colors can no longer meet the needs of consumers.How to carry out a reasonable and feasible secondary innovative design based on multi-color striped fabrics to replace the original monotonous stripes is the challenge to the majority of designers.In this process,it is also a big problem to predict the feasibility of knitting and the color effect of multi-color striped fabrics.Method To quickly generate a feasible design scheme and three-dimensional(3-D)simulation for multi-color striped fabrics,the pattern design models were constructed and the colored-yarn knitting sequence model was generated according to the knitting principle and characteristics of the striping circular weft knitting machine.The types of colored yarn knitted by each knitting system were calculated and the yarn guiding model was generated.According to the yarn arrangement principle,the yarn threading model was established.The loop geometry and translation mapping models were constructed,and the 3-D simulation method of multi-color striped fabrics was explored with coordinate translation mapping.Results The design and simulation of eleven-color gradient striped fabric were taken as an example to verify the knitting feasibility for pattern and threading design on the four-color striping circular machine.The fabric design and 3-D simulation process were used to verify the feasibility of the study method(Fig.2).The pattern model(P)and knitting model(K)were generated according to the pattern design,and the color sequence was reordered from large to small in proportion to produce colored yarn knitting sequence model(Y)(Fig.3).According to the parameters of the knitting machine and the above pattern model,guiding instructions of yarns were assigned to the guiding devices in each knitting system to obtain guiding model(G)(Fig.4).Based on the yarn guiding model,the co
