摘要(Abstract)：

通过熔融纺丝法制备了系列聚酰胺6/黏土/聚乙二醇(PTFs)共混调温纤维,并采用傅里叶红外光谱仪、差示扫描量热仪、热红外成像仪、热失重分析仪和复丝强力仪测试了纤维的结构、热性能、调温性能和力学性能。研究显示,PTFs调温纤维的结晶温度为33℃,结晶焓值达到8.46 J/g,且在100次升降温热循环后调温纤维仍保持良好的热性能。通过模拟冷热环境交替下纤维的温度—时间响应行为发现,在热环境(90℃)和冷环境(10℃)下,调温纤维体现出明显的温度滞后响应,与纯PA6纤维相比温差达到3℃。黏土/聚乙二醇在纤维中的最大质量分数为15%,在牵伸4倍时,纤维的拉伸断裂强度达到3.15 cN/dtex。
In this work, a series of polyamide 6/clay/polyethylene glycol(PTFs) composite fibers were prepared by melt spinning. The fiber structure, thermal properties, temperature regulating properties and mechanical properties of these fibers were tested by Fourier transform infrared spectroscopy(FTIR),differential scanning calorimetry(DSC), thermal infrared imager, thermogravimetric analyzer(TG) and multifilament strength meter. The results showed that the crystallization temperature of PTFs fiber was 33 ℃,the crystallization enthalpy value reached 8.5 J/g, and PTFs temperature regulating fiber still maintained good thermal performance after 100 cycles of heating and cooling. By simulating the temperature-time response behavior of PTFs fibers in the hot and cold isothermal environment, it was found that the temperature regulating fiber exhibited a significant temperature lag response both in the hot environment(90 ℃) and the cold environment(10 ℃), and the temperature difference reached 3 ℃ compared with the neat PA6 fiber. The maximum addition content of the clay/polyethylene glycol in the composite fiber was 15% by weight, and the tensile breaking strength of the fiber reached 3.15 cN/dtex at 4 times of drawing.
