摘要:	複合織物訴求的特性是快乾性暨具有保暖的功能，而提供保暖的因素除了複合織物的厚度外，織物上的含水率(即殘餘水量)亦會影響穿著者對冷暖的感受。複合織物是由針織布及發泡材組合而成，普遍性研究大多專注於針織布或發泡材的開發及改良，以求降低複合織物的含水率。本研究為對針織布及發泡材之間的接著劑層來做疏水性質的改良探討。利用微膠囊的特性，將原本易溶於水的撥水劑改成親油性，撥水劑微膠囊化使其可溶於接著劑裡，續經各段複合織物的製程加工，使針織布及發泡材之間的接著劑層具有斥水特性，來探討能否再降低複合織物的整體含水率，冀能開發更低含水量、快乾性更佳之保溫機能性的複合織物。本實驗利用溶劑揮發法來製備微膠囊，以熱熔膠為殼材，撥水劑為芯材，藉由改變殼芯比、轉速和硬化時間等條件，找出最佳的成型結果。實驗結果顯示，殼芯比以1:10，轉速於600rpm，硬化時間為1小時的條件下所成型之微膠囊為本研究中的最佳條件。在含水率比較試驗中，實驗組接著劑複合織物的初始含水量為對照組接著劑複合織物的73%左右，表示實驗組接著劑能使複合織物有相對較低的初始含水特性。且隨時間增加其乾燥的速率亦皆快於對照組接著劑複合織物，表示實驗組接著劑具有相對較佳的疏水性，亦而提高水份蒸發效率。然在經過1小時吊掛乾燥後，實驗組接著劑複合織物的含水量僅剩初始含水量的50%左右，比對照組接著劑複合織物之初始含水量亦僅剩36%左右，結果可模擬表示衣服在經吊掛陰乾1小時後，可達相對較為快速乾燥之狀態。 The function of the composite fabric is maintaining warm. The main reason of warm aside from the thickness, the amount of moisture remaining in the material will also effect the wearer to feel warm or cold. Composite fabric is composes of knitting fabric and foam material. In general researches, emphasis is always on improving the foam material and knitting fabric to decrease the moisture content. This research will study on how improve the hydrophobic properties of the adhesive between fabric and foam material. Using the properties of microcapsule to modify water repellent agent from hydrophilic to hydrophobic. It causes water repellent agent encapsulation dissolve the adhesive to decrease the total water content. The composite fabric functions become lower water content, making it dry quickly. In this study, we use hot melt plastic as the shell, water repellent agent as the core to prepare the microcapsules encapsulated by solvent evaporation method. By changing the ratio of shell and core, the different stirring speed, and the time of cross-linking, we can find the best condition to prepare the microcapsule. The result shows the ratio of shell and core is 1:10, stirring speed at 600rpm, and cross-linking time at one hour as the best condition. Comparing the remaining water rate test, the initial water content of the experiment group is less than control group about 73%.It shows the adhesive of experimental group enable the fabric to have lower initial water content. And the drying speed is faster than the control group to increase with time. It shows the hydrophobic of the experiment group is better, and also improves the efficiency of water evaporation. However the water content of the experiment group remains the initial water content about 50%, and comparing the control group remains about 36%.Finally the result simulates after clothing hanging for one hour, is dryer.
