ABSTRACT
The phenomenon of impedance finds an application in many areas of science; however, no studies relate to wool. Thus, the aim of the study was an examination of an effect of from the presence of suint layer on sheep wool fibers on impedance and heat resistance values. Electrical characteristics (impedance [Ω]) and heat resistance were compared in terms of wool washing effect. The impedance of wool samples was tested in the frequency range of 10 Hz to 1 MHz. In order to measure electrical characteristics and heat resistance values, five samples of greasy wool were collected from different sheep breeds, standardized by weight. After the analyses, the samples were washed and reexamined. The results showed significant differences in the impedance between the greasy and washed wool samples in each of the tested breed (p > 0.05). The suint layer reduces the impedance level, which was also confirmed by a heat resistance test results demonstrating that absence of suint layer on wool fibers significantly reduced this feature value (p > 0.05). This was also reflected in the weight differences between the examined wool samples before and after their washing.
摘要
阻抗现象在许多科学领域中得到了应用，然而，没有相关的研究。因此，本研究的目的是检查从羊毛纤维上存在的绒毡层对阻抗和耐热值的影响。在羊毛洗涤效果方面，比较了电特性（阻抗[Ω）和耐热性。在10～1MHz的频率范围内对羊毛样品的阻抗进行了测试，为了测定其电特性和热阻值，从五个绵羊品种采集的羊毛样品，按重量标准化。我重新检查了一下。结果表明，各品种的油污和洗涤羊毛的阻抗差异显著（P＞0.05）。SueNT层降低了阻抗水平，这也通过耐热测试结果证实，表明羊毛纤维上没有绒面层显著降低了该特征值（P＞0.05）。这也反映在所检测的羊毛样品在洗涤前后的重量差异。
