Electro-physical Properties of Woven Clothing Fabrics Before and After Abrasion

ABSTRACT

In this investigation, the electro-physical properties (DC volume electrical resistivity, and AC-specific electrical conductivity) of woven fabrics (cotton, cotton/polyester, and flax in plain weave and cotton in satin weave), before and after abrasion on Martindale device (under a pressure of 9 and/or 12 kPa) were examined. The obtained results revealed that the cotton fabric in satin weave has the lowest resistivity and the highest conductivity. In contrast, the lowest conductivity and the highest resistivity before abrasion were observed for cotton/polyester fabric due to its lowest moisture content. Furthermore, a decrease in the conductivity and increase in the resistivity of cotton/polyester and flax fabrics in plain weave, and cotton fabric in satin weave, as well as an increase in the conductivity and decrease in resistivity of cotton fabric in plain weave were registered after abrasion at 9 kPa. After abrasion at 12 kPa cotton and cotton/polyester blend fabrics in plain weave have higher resistivity and lower conductivity than before abrasion and after abrasion at a pressure of 9 kPa. Abrasion leads to a deterioration of the fabrics’ electro-physical properties and thus their comfort, especially in the case of cotton/polyester blend fabric when the pressure of 12 kPa was applied.

摘要

本文研究了机织物（平纹棉织物、缎纹棉织物、棉/涤纶织物和亚麻织物）在马丁代尔装置（压力为9和/或12kpa）上磨损前后的电物理性能（直流体积电阻率和交流比电导率）. 结果表明，缎纹棉织物的电阻率最低，电导率最高. 相比之下，棉/涤纶织物在磨损前的电导率最低，电阻率最高，因为其含水量最低. 此外，在9kpa磨损后，平纹组织中的棉/涤纶和亚麻织物以及缎纹组织中的棉织物的导电性降低和电阻率增加，平纹组织中的棉织物的导电性增加和电阻率降低. 在12kpa压力下磨损后，平纹组织中的棉和棉/涤纶混纺织物比磨损前和磨损后在9kpa压力下具有更高的电阻率和更低的电导率. 磨损会导致织物的电物理性能和舒适性的恶化，尤其是棉/涤纶混纺织物在施加12kpa压力时.
