以相变材料硬脂酸丁酯为芯材，异氟尔酮二异氰酸酯（IPDI）和三乙醇胺（TEA）为反应单体，采用界面聚合法制备聚氨酯网状相变微胶囊，通过涂层法将微胶囊整理到棉织物上。对相变微胶囊的表面形貌、化学结构和热稳定性进行表征，优化了整理工艺，对比了整理织物前后的表面形貌，研究了整理后织物的耐水洗性、储热性能和调温效果。结果表明，微胶囊表面光滑致密、无凹陷，制得的微胶囊壳体具有聚氨酯结构，在260℃芯材完全失重时，微胶囊的保留率为53.8%，热稳定性较好；当整理织物为3.5 g、微胶囊和粘合剂均为1.0 g时，耐水洗性较好，储热明显，调温效果优良。

Netlike polyurethane-based phase change microcapsules are prepared via interfacial polymerization,using phase change material butyl stearate as core material,isophorone diisocyanate (IPDI) and triethanolamine (TEA) as monomers.The prepared microcapsules are finished on cotton fabrics through coating finishing method.Surface morphology,chemical structure and thermal stability of the phase change microcapsules are characterized and the fabric finishing process is optimized.The surface morphologies of finished fabrics are compared before and after the finishing.The washing durability,heat storage performance and temperature monitor effect of finished fabrics are also studied.Study results show that the microcapsule has a smooth and dense surface without any concave.The prepared polyurethane shell of microcapsule has a structure same as polyurethane.The microcapsule retention rate is still 53.8% when the core material has lost completely its weight at 260℃,representing a good thermal stability.The finished fabrics exhibit high water washing resistance,obvious heat storage ability and excellent thermostat effect when the amount of fabrics to be finished is 3.5 g and both the dosages of microcapsule and binder are 1.0 g.
