相变材料在调温纤维上的应用

Preparation of Temperature-Conditioning Fibres Based on Phase Change Material

利用溶胶-凝胶复合相变材料(A/SiO2),并用DSC对其热性能进行了测试。考察了水/酯摩尔比、反应温度、搅拌速度、pH值、陈化温度、酯/相变材料摩尔比等因素对胶凝时间及纤维调温性能的影响,筛选出最佳工艺。采用涂层法将复合相变材料整理到织物上。结果表明:复合后相变材料具有较高相变焓;复合相变材料的相变焓、相变温度均较纯相变材料稍有降低;织物经相变材料涂层整理后具有良好调温性能。

The phase change material is prepared by sol-gel technique and the effects of water/ester molar ratio, reaction temperature, stirring speed, pH, seasoning temperature, and molar ratlio of ester/phase change material on sol-gel time and the temperature conditioning property of the fibre are investigated. And the optimal process conditions are determined.
