A Study on the Ignition Behaviors of Textiles according to Permeation Amount of Oils and Aeration
면화류의 열적특성을 조사하기 위하여 시차주사열량계(DSC, Differential Scanning Calorimeter) 및 열중량 분석기(TGA, Thermogravimetric Analysis)를 이용하여 온도에 따른 발열개시온도, 무게감량 등을 조사하였으며, 발화온도 측정방법 중 정온법을 이용하여 요오드가가 각기 다른 유지류에 침윤된 면화류의 발차거동을 조사하였다. 이때 발화온도 측정장치의 반응용기 내부로의 공기 기류의 존재 여부에 따른 발화거동을 함께 조사하였다. 연구결과 합성섬유의 분해온도 폭이 순면인 천연섬유에 비하여 다소 넓음을 알 수 있었다. 한편 발화개시온도의 경우 공기를 주입하지 않는 경우에는 유지의 침윤량 증가에 따라 두 시료 모두 상승하였으나, 공기를 주입하는 경우에는 유지의 침윤량 증가에 따라 상당히 낮아지고 있으며, 특히 건성유를 침윤시킨 경우에는 급속히 감소하고 있음을 확인할 수 있었다.
We had investigated thermal and ignition behaviors of textiles. Decomposition of textiles with temperature was investigated using a DSC and the weight loss according to temperature using a TGA in order to find the thermal hazard of textiles, and the ignition behaviors of textiles according to species and permeation amount of oil. In addition, ignition behaviors of those permeated into oils indicating different iodine value and of those with arid without air in reaction vessel of measuring equipment were studied with constant temperature method among ignition temperature measuring methods. As results, the range of decomposition temperature of synthetic fiber was slightly broad compared with that of natural fiber, pure cotton. Besides, the initiation temperature of heat generation of both samples riced in the case of no air injection in the reaction vessel. On the other hand, in the case of air injection that was lowered according to the increase in permeative amount of oils and fats and decreased quickly as sample was permeated into drying oil.
Key Words: textiles, thermal hazard, ignition temperature, permeation, drying oil
