经编浮纹贾卡提花原理

针对目前国内外对经编浮纹贾卡提花原理研究甚少，在其实际应用中受瓶颈制约，本文研究了浮纹型贾卡提花织物的特点和基本形成原理，并在此基础上对选针原理、钩针运动规律进行了深入的分析和探讨。根据上机实验采集的数据，建立了钩针位移曲线模型，对应空间和时间的二维坐标，更为深入合理地描述了钩针的运动特性。此外，还建立了单纱选择的图示模型，详细阐明了单纱选择的具体实现过程及其实现路线。最后，分析了浮纹贾卡提花的压纱结构，探寻出适合浮纹贾卡提花的压纱方式，并且还比较了浮纹花纹和绣花花纹、剪线花纹在形成原理上的区别，体现出浮纹花纹在生产和性能方面的综合优势。以上研究可为经编浮纹贾卡提花机构及产品的设计提供参考。

Principle of warp knitted Broché jacquard

In view of the fact that the theory of warp knitted broché Jacquard is rarely studied, here and abroad, and its technology bottleneck in application field, this paper probes into the characteristics and basic principle of broché jacquard fabric. Based on the content, an in-depth analysis and investigation on the needle selection principles, and movement rules of crochet hook are undertaken. According to the statistics from experimental trials on the machine, the displacement curve model of crochet hook, corresponding to the space and time axis, is built, and thus its motion characteristics are more deeply and rationally illustrated. In addition, the graphical model of single-yarn selection is also built which explains in detail the concrete realization process of single-yarn selection and its implementation route. Lastly, the structure of broché jacquard fall-plate lapping is analyzed, meanwhile, a suitable mode for broché jacquard is equally figured out. Moreover, after a comparison in formation theories with the embossed pattern and slap-up cutting pattern, the broché pattern demonstrates its own comprehensive advantages in terms of production and performance. The above research on principles about warp knitted broché Jacquard could provide a reference to the design of broché jacquard machine as well as its products.
