摘　　要：采用LDMG-1型寝具保温仪和LD-1型服装保温仪,研究纺织品冷暖感在测试的物理量上的反映以及冷暖感的表征指标,以弥补主观评价和采用瞬态热流量最大值Q_(max)表征纺织品冷暖感的缺陷。选取8款不同材质和不同填充量的寝具和2类不同材质的服装作为试样,通过研究和分析,获得如下结论:纺织品的冷暖感在试验板消耗的加热功率曲线和温度曲线上都有明显反应,但是,加热功率曲线更能够反映纺织品的冷感特性;纺织品冷暖感应该用冷感时间和冷感散热量两方面指标进行表征。冷感散热量指标包括冷感时段总散热量(W_1)和纯冷感散热量(W_2),后者比前者更具可比性。冷感时间越长、纯冷感散热量越大,冷感越强。By using LDMG-1 insulation tester and LD-1 clothing thermal insulation tester,the reflection and indexes of textile’s warm-cool feeling are studied,compensating for the defects of using subjective evaluation and the maximum transient heat Qmax to characterize the warm-cool feeling of textile.Eight bedding samples with different core materials and fabrics and two apparel samples with different materials are tested.The main conclusions are as follows：there is a clear reaction to the warm-cool feeling of textile in thermal power and temperature curves of test board,but thermal power curves can better reflect textile’s cool feeling;the warm-cool feeling of textile should be characterized by warm-cool feeling time and amount of heat.The amount of heat includes the total amount of heat W1 and pure amount of heat W2,and the latter is more comparable than the former.The longer the cool-feeling time is,or the bigger the W2 is,the stronger cool feeling will be.
