摘要
采用热重和差热分析方法测试了北极狐绒毛的热学特征,以及不同温度、时间的热处理对纤维强力、强伸度的影响.实验结果表明,随温度升高北极狐绒毛的TG曲线有两个失重阶,DSC曲线呈现出与羊毛、山羊绒相似的双熔融峰;在热分解温度的前后北极狐绒毛纤维的断裂强力和断裂伸长率呈先上升后下降趋势.
The arctic fox wool＇s thermal characteristics was tested by TG and DSC , and the impact of different temperatures,time of heat treatment on fiber strength and elongation were also studied. Experimental results show that as the temperature increases, the arctic fox wool＇s TG curves appear two weightlessness bands, DSC curve appeares double melting peaks which is similar to cashmere and wool＇ s. Before and after the thermal decomposition ,the arctic fox wool＇s break strength and elongation go up first and drop after.
