本研究探討軟組織、100%棉質和100%聚酯纖維衣料，在不同強度之遠紅外線及照射時間下，溫度隨深度之變化情形，以探討軟組織深度及衣料之材質和厚度對於遠紅外線之熱量傳遞的影響。研究結果發現，經45℃及65℃等兩種不同表面溫度之遠紅外線放射器照射60分鐘後，在37℃恆溫下之豬肉樣品的深層組織(4.6 cm)分別提升至38.7℃及39.1℃。此外，在經45℃及65℃兩種表面溫度之遠紅外線照射20分鐘後，可發現23℃恆溫下之100%棉質衣料，其0.5 cm深處之溫度分別提升至30.7℃以及39.1℃，而在100%聚酯纖維相同深處，其溫度則分別提升至33.9℃以及42.4℃；顯示聚酯纖維之傳導速率較棉質快。本研究結果可提供遠紅外線之使用者及臨床研究與應用的參考，以針對照射部位之組織或器官組成，適度調整強度與照射時間，而達到較佳之治療效果。此外，建議在臨床應用上，患者所著衣物採用聚酯纖維衣料並減少衣料厚度，以降低遠紅外線之強度衰減。 This research aimed to investigate the variation of temperature inside the soft tissue, 100% cotton and 100% polyester cloths under the irradiation of different intensity of far-infrared ray (FIR) with different irradiation time, so that to probe the effect of the thickness of soft tissue and cloth as well as the cloth materials on thermal transmission by far-infrared ray. The results indicated that the temperature at 4.6 cm deep from surface of the (pork) tissue sample rose from 37℃ to 38.7℃ and 39.1 ℃ after 60 min of irradiation with a FIR emitter whose surface temperature was respectively adjusted as 45℃ and 65℃. Besides, after 20 min of irradiation with the FIR emitter by setting the surface temperature as 45℃ and 65℃, the temperature at 0.5 cm deep from surface of the 100% cotton cloth rose from 23℃ to 30.7℃ and 39.1℃ while that of the 100% polyester cloth rose from 33.9℃ to 42.4℃. This represented that the rate of thermal conduction of polyester is faster than that of cotton. The results of this research provide a reference for FIR users as well as clinical research and applications to appropriately adjust the FIR intensity and irradiation time according to the composition of the irradiated tissues or organs to obtain better effects of healing. Furthermore, thinner polyester clothes were suggested for the dressing of patients in clinical use.
