无结网编织工艺研究

Study on braiding of knotless netting

针对当前无结网成网技术中存在织物质量较差和内部纤维强度损失较大的问题,研究了一种新型无结网状织物的编织工艺。通过结合编织技术原理与无结网结构特征,分析了无结网成型原理,并以四纱网脚作为研究对象,对其网脚及网结的编织轨道形式进行了设计,进而探讨纱锭无干涉分布规律。在此基础上对纱锭无干涉分布规律进行拓展,分析了采用4个多槽口叶轮编织多纱无结网的纱锭分布规律。依据纱锭在轨道盘上的无干涉分布规律获得可行分布方案,针对某个分布方案进行无结网实物编织实验,验证了所研究无结网工艺的合理性,并确认无结网的编织工艺需综合考虑纱锭运动轨道、纱锭分布及叶轮规格的影响。

In order to solve the problem of the poor quality or losing of fiber strength in the fabric due to the existing knotless netting production technology, the braiding technology of a new type knotless netting was studied. The knotless netting forming principle combining with its structure characteristic and the braiding principle was analyzed. With a kind of four-thread braided leg as the research object, the tracks of braiding net legs and net knots were designed. According to the form of the tracks, the rule of non-collision initial arrangement of spindles were studied. Finally, on the basis of this research, the rule of arrangement was extended with braiding multi-thread knotless netting by four multi-slot horn gears. The rule of non-collision initial arrangement of spindles was summarized and a limited number of feasible arrangement schemes was obtained. Then a knotless netting real object was braided adopting a feasible arrangement to verify the rationality of the braiding process. The results show that the moving path and the arrangement of spindle, and the specification of horn gears should be taken into account during the process of braiding knotless netting.
