摘要

本研究以鍍碳耐隆／聚酯紗與Lycra®／聚酯彈性包覆紗織製Lycra®彈性導電織帶，探討單層編織結構、雙層梭織結構、與不同鍍碳耐隆／聚酯紗根數對Lycra®彈性導電織帶於拉伸－回復過程中所產生的接觸電阻現象。以自行設計的拉神－電阻量測儀，進行Lycra®彈性導電織帶於拉伸－回復循環過程的應變－電阻曲線之量測。結果顯示，Lycra®彈性導電織帶的應變－電阻呈線性關係，且拉伸－回復循環之應變－電阻曲線幾乎沒看遲滯現象。隨著鍍碳耐隆／聚酯紗根數增加，碳黑與碳黑間及碳黑與電極間的接觸界面增加，導致接觸電阻比例增加。由於雙層梭織結構中的鍍碳耐隆／聚酯紗與電極的有效接觸率較低，導致雙層梭織結構之Lycra®彈性導電織帶的接觸電阻比例高於單層編織結構。

Two Lycra® elastic-conductive webbings such as single-layer flat structure and double-layer belt structure, made of carbon coated PA/PET yam and Lycra®/PET yam, were used in this study. The effects of webbing structures and carbon coated PA/PET yam number on the contact resistance of the webbings were evaluated under the three extension-recovery cycles. The strain-resistance curves of the webbings at 30% strain of extension-recovery cycles were measured using a self-assembled strain-resistance apparatus. It was found that the tensile strain was proportional to the resistance for all of the webbings. No resistance hysteresis was observed. When the number of carbon coated PA/PET yams increased, the contact interface between carbon particles and between carbon particles and electrodes increased, which resulted in the increase of contact resistance. Compared with double-layer belt webbing, the single-layer flat webbing had better contact characteristics between carbon coated PA/PET yams and electrodes. Therefore the contact resistance in single-layer Lycra® elastic-conductive flat webbing was lower than that in double-layer Lycra® elastic-conductive belt webbing.
