Application of the Electrical Impedance Analysis Method, Combined With Measurments Heat Resistence and Breaking Strength on The Comparison of Natural Wool Fibers of Selected Species of Animals with Polyacrylonitrile (PAN) Fiber

ABSTRACT

The production of clothing in recent years is mainly based on synthetic materials. Synthetics such as polyacrylonitrile fiber (PAN) significantly reduce the costs of clothing production. PAN fiber requires considerably more water than natural fibers in the treatment process, which has a negative impact on the environment. This is quite different in the case of natural fiber wool, which is a biodegradable material. Due to the high quality of its products, wool is also a material highly appreciated by the textile industry. Differences between the materials were determined by testing electrical properties (resistance and impedance), which may represent differences at the molecular level. As the use of the proposed method is at the preliminary stage, measurements of fiber diameter, heat resistance, and breaking stress were also performed to supplement the results. The electrical characteristic tests showed a higher resistance of wool compared to PAN fiber, which indicates that wool is a better dielectric than PAN fiber. The breaking stress tests showed that PAN fiber was the weakest of the assessed fibers. The measurements have also shown that the heat resistance of the samples of wool from alpaca were higher than those of PAN fiber. The wool samples from angora goats were characterized by the lowest heat resistance.

摘要

近年来服装生产主要以合成材料为主. 合成纤维如聚丙烯腈纤维（PAN）显著降低了服装生产的成本. PAN纤维在处理过程中比天然纤维需要更多的水，这对环境有负面影响. 这是在天然纤维羊毛，这是一种生物可降解材料的情况下是完全不同的. 由于其产品质量高，羊毛也是纺织业高度赞赏的材料. 材料之间的差异是通过测试电性能（电阻和阻抗）来确定的，这可能代表分子水平上的差异. 由于该方法的应用还处于初步阶段，因此还对纤维直径、耐热性和断裂应力进行了测量，以补充结果. 电性能测试表明，羊毛比PAN纤维具有更高的电阻，表明羊毛比PAN纤维具有更好的介电性能. 断裂应力测试表明，PAN纤维是被评定纤维中最弱的. 测定结果表明，羊驼羊毛样品的耐热性高于PAN纤维.安哥拉山羊羊毛样品耐热性最低.
