采用界面聚合法制备了含有十八烷的三聚氰胺甲醛微胶囊，并通过FFIR、SEM和DSC对合成的微胶囊的大小、形状和储放热性能进行了分析。然后在不同的浓度和时间/温度条件下，通过刀卷（KOR）和丝网印刷（SP）方法将微胶囊涂覆在聚酯织物上。对未处理和处理织物的热、机械和物理性能进行评估，以确定最佳粘合方法。微囊的平均直径为1 ~ 1.5 μ m，形状接近球形。在最佳处理浓度、温度和时间下，5次洗涤后的热学性能迅速下降，KOR织物的弯曲刚度和剪切刚度均高于sp织物。这意味着sp涂层的织物比KOR涂层的织物变得不那么僵硬和坚硬。sp织物比KOR织物具有更高的透气性和更低的吸湿性。
Melamine formaldehyde microcapsules containing octadecane are synthesized by the interfacial polymerization method, and the size, shape, and thermal storage/release properties of the synthesized microcapsules are analyzed by FFIR, SEM, and DSC. Polyester fabrics are then coated with the microcapsules under various conditions of concentration and time/temperature by the knife-over-roll (KOR) and screen printing (SP) methods. The thermal, mechanical, and physical properties of the untreated and treated fabrics are evaluated to identify the best adhesive method. The mean diameter of the microcapsules ranges from 1 to 1.5 mum, and their shapes are almost spherical. Under the optimum treatment concentration, temperature, and time, thermal properties after five launderings decrease rapidly, and the bending and shear rigidities of the KOR fabrics are higher than those of the sp fabrics. This means that fabrics coated by sp become less stiff and hard than those by KOR. sp fabrics exhibit higher air permeability and lower hygroscopic properties than KOR fabrics.
