摘要:
为了进一步开发具有实际意义的负泊松比针织物,并探讨工艺参数对负泊松比效应的影响,基于折叠结构对负泊松比纬编针织物进行设计。根据产生负泊松比效应的折叠结构原理建立几何模型,并推导出各几何参数与负泊松比值间的关系; 分别改变花型针数和行数的比值、线圈长度两种工艺参数,使用电脑横机花型软件对负泊松比纬编织物进行设计并织造; 对各织物进行负泊松比测量并分析测量结果,探讨工艺参数与几何参数之间的联系。结果表明:张角θ是影响负泊松比折叠针织物的重要几何参数,因为花型针数和行数的比值、织物线圈长度两种工艺参数的变化都使张角θ改变,从而导致负泊松比值的变化。
Abstract:
In order to further develop practical negative Poisson’s ratio knitted fabrics and explore the influence of process parameters on the negative Poisson’s ratio effect, a negative Poisson’s ratio weft knitted fabric was designed based on the folded structure. Firstly, a geometric model is established according to the principle of folding structure with negative Poisson’s ratio effect, and the relationship between each geometric parameter and the value of negative Poisson’s ratio is deduced. Negative Poisson’s ratio weft-knitted fabrics were designed and woven by computerized flat knitting software; finally, the negative Poisson’s ratio was measured for each fabric and the results were analyzed to discuss the relationship between process parameters and geometric parameters contact. The results show that the opening angle θ is an important geometric parameter that affects the negative Poisson’s ratio folded knitted fabrics. Changing the ratio of the number of pattern stitches to the number of rows and the length of the stitches of the fabric is due to the change of the opening angle θ. Causes a change in negative Poisson’s ratio.
