摘　　要：采用自制热效应测试仪与平板保温仪对纺织品的蓄热性能及保暖性能进行测试,测试出纺织品的加热功率、模拟太阳光辐照阶段的温度及冷却阶段的温度,推导纺织品的蓄热变化率及保温变化率的计算公式,计算纺织品的蓄热变化率及保温变化率,表征纺织品的蓄热性能及保暖性能。结果表明:该纺织品的蓄热变化率为23.5 J/min,保温变化率为0.1℃/min,该检测方法可以表征纺织品的蓄热性能及保暖性能。This paper adopted homemade mechine and guard heated plate instrument to test thermal retention with accumulated of textiles, got heating power of textile, the temperature under simulated sunlight irradiation stage and cooling stage, deduced formula for calculating thermal retention with accumulated of textiles, calculated regenerative rate of change and heat rate of change to characterize regenerative property and thermal performance. The results showed that regenerative rate of change was 23.5 J/min, heat rate of change was 0.1 ℃/min, this test method could characterize regenerative property and thermal performance of textiles.
