摘要
为开发具有实际意义的负泊松比织物,探讨工艺参数对织物拉胀效果的影响。基于歪斜的六角网眼,采用旋转结构受到拉伸时展开扩张的原理进行负泊松比经编织物的设计。实验选用涤纶低弹丝编织地组织,前梳采用锦纶编织缺垫与编链组织,设计了4种组织方案,通过调节每种组织方案下织物的前梳送经量,对各工艺参数的影响进行分析。实验结果表明,原料的性能,特别是纱线的刚度和弹性对织物负泊松比效果有很重要的影响;前梳编链组织结构的送经量对织物的负泊松比效果也有一定的影响,同时织物的负泊松比性能与地组织的歪斜程度具有明显的关系。
In order to develop a realistically applicable auxetic fabric and study the influence of production parameters on its auxetic performance, the principle of rotational structures based on deflective tulle nets which unfold when being stretched was adopted to the design of the auxetic warp knitted fabrics. Polyester DTY was chosen to knit basic structures and nylon was used for miss-lapping chains of front bar. Then four knitting plans were designed and let-off values of each sample were adjusted during the weaving process to summarize the effectiveness of all the factors. Experimental results show that properties of yarns have a significant influence on fabric auxetic effects, especially on yarns stiffness and elasticity. The let-off values of front bars＇ chain parts also have some effects and its auxetic properties have a complicated correlation with the degree of tulle nets deflection as well.
