摘要
采取“结构设计-经向截面-组织结构”的思路设计了六边形蜂窝结构三维织物,对比分析了逐层分引织造法、多梭同引织造法用于蜂窝三维织物织造过程的优缺点。在此基础上建立了六边形蜂窝结构三维织物的理论模型,并探讨了六边形蜂窝形态的影响因素。结果表明,多梭同引织造法更适合蜂窝三维织物的织制,相对于逐层分引织造法而言,前者虽换梭频繁,但所形成的三维织物层间歪斜及打纬不紧现象得到明显改善,织物结构较均匀。单层织物纬密Pw、每边纬纱数量n是影响六边形蜂窝截面形态的重要因素,在Pw一定的前提下,蜂窝截面积S随着n的增加而增大;在n一定的前提下,蜂窝截面积S随着Pw的增加而减小。
Hexagonal honeycomb structure three-dimensional fabric is designed in the way“structure design-cross section-organization structure”.Hierarchical weaving method is compared with multi-shuttle insertion method on their advantages and disadvantages in the weaving process of three-dimensional fabric.Based on this,hexagonal honeycomb structure three-dimensional fabric theory model is built and the influencing factors of hexagonal honeycomb structure are researched.The results show that the multi-shuttle insertion method is more suitable for honeycomb structure three-dimensional fabric.Compared with the hierarchical weaving method,although the former changes shuttles frequently,the skew appearance layer by layer and beating up loosely of the three-dimensional fabric are significantly improved,and the fabric structure is more uniform.The flat fabric weft density(P_w)and number of yarn on each side(n)are the important factors affecting the hexagonal honeycomb section.Under the premise of Pw being constant,the honeycomb cross-section area(S)increases with the increase of n.However the honeycomb cross-section area(S)decreases with the increase of P_w under the premise of n being constant.
