本研究以揮發性精油為芯材及水性聚氨酯基甲酸酯(Aqueous polyurethane)為殼材，利用微膠囊製備法中的溶劑揮發法製備微膠囊。藉由使用不同分散劑找出最佳分散效果、並改變殼芯比例及轉速(即攪拌速度)來探討微膠囊的包覆率與粒徑大小。結果顯示，在使用1%PVA為分散劑時所得分散效果最佳且在殼芯比為8:1時，微膠囊具有較佳之包覆率及制放效果。在轉速為400rpm、800rpm、1200rpm，平均粒徑分別為521.91±29.25?m、500.23±28.5?m、468.13±28.53?m，可發現隨轉速的提高，微膠囊的粒徑有變小的趨勢。制放極限時間之分析結果，在轉速為400rpm、800rpm、1200rpm時，經估算分別可達45.5hr、28.3hr、23.9hr，故得知隨轉速的提高，制放時間有變快的趨勢。在30℃、40℃、50℃和60℃時，精油經包覆後比精油的制放時間分別提升2.35倍、3.13倍、3.25倍和3.52倍。

本實驗針對聚酯織物包覆遠紅外線纖維在加入人工汗液後，其紅外線放射率變化情形進行放射率紀錄與分析。本研究針對纖維的種類、重量、人工汗液用量的改變對聚酯織物包覆之紅外線織物放射率影響進行觀察。結果顯示，遠紅外線纖維的放射率約為0.86；而棉纖維的遠紅外線放射率約為0.79，兩者放射率相差0.07。而在聚酯織物包覆下，遠紅外線纖維使用量的多寡對放射率不會有太大影響。在加入汗液後，遠紅外線放射率初期會因汗液而下降，但隨著人工汗液的蒸發，放射率也會緩緩上升至原定數值。另不同重量遠紅外線纖維樣本經多次滴定汗液後，遠紅外線纖維樣本之放射率會上升約0.005 ~ 0.007。
