Abstract Herein, the effect of twist on physical properties such as tensile, hairiness and wicking behavior of our reported tri-component elastic-conductive composite yarns (t-ECCYs) was systematically studied. Experimental results revealed that an optimum twist value provided the maximum yarn strength. A positive relation between extension at break and twist was observed. Significant differences in the tensile behavior is established. Two-parameter Weibull distribution and boxplots were used to quantify the variation in yarn strength. The role of spinning geometry and variation in twists on hair formation was highlighted, with an increase in twist reducing yarn hairiness. In addition, t-ECCYs with higher twist exhibited poorer wickability, and there was a gradual increase of the equilibrium height of yarn under extension. Importantly, the results demonstrated that the Laughlin-Davies wicking model was valid for t-ECCYs under tested conditions. It is promising that the as-fabricated t-ECCYs is prerequisite for the next wave of smart yarns and large-scale stretchable protective devices, such as superstretchable helical-structured yarn heaters and elastic electromagnetic shielding fabrics.

在改进的环锭纺纱系统上生产的含有金属丝的螺旋形弹性复合纱线的捻度相关行为

摘要 本文系统地研究了捻度对我们报道的三组分弹性导电复合纱线(t-ECCYs)的拉伸、毛羽和芯吸行为等物理性能的影响。实验结果表明,最佳捻度值可提供最大的纱线强度。观察到断裂伸长率和扭曲之间的正相关关系。建立了拉伸行为的显着差异。双参数威布尔分布和箱线图用于量化纱线强度的变化。纺纱几何形状和捻度变化对毛发形成的作用得到强调,捻度的增加减少了纱线毛羽。此外,具有较高捻度的t-ECCYs表现出较差的芯吸性,并且拉伸下纱线的平衡高度逐渐增加。重要的,结果表明,Laughlin-Davies 芯吸模型对于测试条件下的 t-ECCY 是有效的。有希望的是,所制造的 t-ECCYs 是下一波智能纱线和大规模可拉伸保护装置的先决条件,例如超拉伸螺旋结构纱线加热器和弹性电磁屏蔽织物。
