采用熔融共混挤出,将高效率光热转化粉末材料碳化钛(TiC)均匀分散到聚酯中,再以制备的复合聚酯材料与聚酯进行共混、熔融纺丝,即制备得到不同比例的TiC的高效光热转化发热聚酯纤维。通过扫描电子显微镜、傅里叶红外光谱仪、NETZSCH热失重仪、红外测温仪等手段测试了所制备发热聚酯纤维的光热转化性能和发热性能。结果表明,含有0.5%碳化钛发热粉体的发热聚酯纤维在充分满足服用纤维机械强度标准的同时还可以很好地将温度控制在人体比较舒适的温度。
Using melt blending extrusion, the high efficiency light-heat conversion powder material titanium carbide (TiC) uniformly dispersed in the polyester, and then the prepared composite polyester material and polyester blending, melt spinning, that is, the preparation is different Proportion of TiC efficient photothermal conversion of heat-generating polyester fibers. The photothermal conversion properties and heat-generating properties of the heat-producing polyester fiber were tested by scanning electron microscopy, Fourier transform infrared spectroscopy, NETZSCH thermogravimetry and infrared thermometer. The results show that the pyrolysis polyester fiber containing 0.5% titanium carbide heating powder can sufficiently control the temperature of the human body at the same temperature while fully meeting the mechanical strength standard of the fiber.
