This research focuses on a three-dimensional jacquard spacer fabric, which has two sets of jacquard yarn systems to form double-appearance patterns. Because of the unique structure and formation characteristics, a specific computerized patterning model needs to be solved for efficient jacquard structure design. After a systematic analysis of double-needle bed knitting and the piezo-jacquard principle, a loop index is proposed to coordinate jacquard loops and define the single-loop-based jacquard bitmap. Also, an algorithm is derived to solve offset data to guide the knitting action by inferring the jacquard bitmap and the corresponding loops hypotaxis. This new patterning method is proposed based on two basic elements of the jacquard bitmap and lapping data. In comparison with the traditional two-course bitmap method, the new approach shows the advantage of more simplified operations by a significant decrease of jacquard color definitions.

本次研究的重点是一种三维提花间隔织物，它具有两套提花纱线系统，形成双重外观图案。由于独特的结构和形成特征，需要解决特定的计算机化花样模型以进行高效的提花结构设计。在对双针床针织和压电提花原理进行系统分析后，提出了一个线圈索引来协调提花线圈并定义基于单线圈的提花位图。此外，还推导出了一种算法来解决偏移数据，通过推断提花位图和相应的环线形来指导编织动作。这种新的花型方法是基于提花位图和搭接数据两个基本要素提出的。与传统的两道菜位图方式相比，
