本研究以水性壓克力與水性PU混合為殼膜，石蠟膜為相轉變材料與偶氮發泡劑混合做為核芯材料。改變攪摒速度、反應溫度、水性PU含量，分析其粒徑大小及整理加工後之耐水洗牢度、透氣度、柔軟度及蓄熱保溫性的測試。由實驗結果顯示：攪拌速度會影響到粒徑大小、分散狀態及數量，而反應溫度會影響到微膠囊之固化程度。水性PU含量則會影響著織物整理加工後之耐水洗牢度、透氣度、柔軟度。相轉變材料之包埋有利於織物蓄熱保溫性之提升。
The study was aim at the phase change material microcapsules which were prepared from waterbrone acrylic and waterbrone polyurethane as wall material, paraffin as phase change material, and azo foaming agent as core material. The particle size of microcapsules and the evaluation of finishing were investigated by varing stirring speed, the temperature of reaction and amounts of waterbrone polyurethane. The experimental results showed that the stirring speed affected the particle size distribution and amounts of microcapsules, and the temperature of reaction affected the solidification degree of microcapsules. The introduced amount of waterbrone polyurethane affected the washing fastness, air-permeability, and softness of the fabric after finishing. The microcapsulation of phase change material were in favor of increasing the theat-regenerating of fabrics.
