摘要

依瞬間涼爽性織物國家標準CNS15687，應用熱板瞬間穿透織物熱適量之Q-max值，本研究另增加織物間含水率之熱傳導函數評估於實際應用於織物與人體接觸上以CNS15659-1及15659-2標準測試乾爽過程之散熱溫差評估，研究結果比較涼爽織物和吸濕發熱織物Q-max值，發熱織物的Q-max值均高於一般涼爽織物的標準，如TCP的Q-max值為0.198，而100%遠紅外線嫘縈的吸濕發熱織物Q-max值為0.241，說明涼爽織物在Q-max值上較不易散熱，但TCP濕阻熱溫差為8.5℃，所維持的涼爽時間8分鐘，其乾燥速率較快，相反100%遠紅外線嫘縈的濕熱阻溫差為較小為7.2℃，在濕狀態下可維持涼爽時間有22分鐘，但較不乾爽，綜合織物涼爽標準測試宜包含Q-max、濕熱阻溫差、乾燥後熱阻溫差等三項。

Follow CNS15687 standard, using heating board to translate heat on the textile in order to reach the Q-max data. In this research, adding thermal conductivity and moisture regain of textiles. Also, considering about the practically use of textile that touching the human body. CNS15659-1 and CNS15659-2 standard to assess the heating generating by moisture absorption on textiles. The result of the research, the Q-max of the heating textiles are higher than the cooling Textile. For example, the Q-max of TCP is 0.198, but the Q-max of 100%far infrared rayon is 0.241. The TCP temperature is 8.5 ℃, difference are higher than every testing textiles, the continuous of cooling time of TCP have 8 minutes, and easy drying. Far infrared rayon is 7.2℃, and cooling time have 22 minutes, longer than TCP a double time with wet condition. The standard testing of cooling textiles need to consider with the thermal conductivity of temperature with dry and wet condition.
