Title: | Auxetic yarn made with circular braiding technology | Authors: | Jiang, N Hu, H |
Issue Date: | Jan-2019 | Source: | Physica status solidi. B, Basic research, 2019, v. 256, no. 1, 1800168, p. 1-12 | Abstract: | This paper reports a new type of auxetic yarn made with circular braiding technology to overcome the yarn slippage problem in the conventional helical auxetic yarn structure. Various auxetic yarn structures are firstly produced on a vertical circular braiding machine with 16 yarn carries by changing the number and arrangement of stiff yarn as well as diameter of elastic yarn and core yarn, and then tested under single and repeating tensile conditions. The results show that not only yarn slippage problem could be overcome in the newly developed auxetic yarn structure, but also an early activation and a higher magnitude of negative Poisson's ratio could be achieved. The results also show that all structural parameters including stiff yarn number and arrangement, core yarn, and elastic yarn diameter have an influence on the auxetic effect of the novel yarn structure. Since the new auxetic yarn is produced by using standard braiding manufacturing technique and conventional non-auxetic yarns, there are few technological barriers for its large-scale manufacture for practical application. | Keywords: | Auxetic yarn Braiding Deformation behavior Negative poisson's ratio |
