摘要

本論文研究之主題包括三個部分：第一部分為研究水性PU應用於聚酯織物抗靜電劑之製備及耐久性探討，經實驗結果證明在本實驗中某些抗靜電劑對於聚酯織物具有耐久性的抗靜電整理效果。
第二部分為研究水性PU應用於純棉織物抗皺整理劑之合成及其物性之探討，由實驗結果顯示經水性PU加工處理過之純棉織物其抗皺性能有明顯之增加。
第三部分為研究水性PU/clay之奈米複合材料，亦即先將奈米黏土有機改質後，採三種不同之製備方式將有機黏土依不同之重量比例添加於其中。由實驗結果得知，黏土在有機改質前後其WAXD繞射圖之2θ值分別為7.88及4.7，其d-spacing增加了0.76nm，此一結果顯示黏土之有機改質已成功。而將水性PU與有機黏土所製備成的奈米複合材料經由WAXD測試結果得知有機黏土呈現插層或剝層形態分佈於水性PU中。此外藉由TGA、DSC及拉力試驗機測試結果顯示出本實驗部份之水性PU/clay奈米複合材料在熱性質與機械性質這兩方面有增加之趨勢。

The waterborne polyurethane was synthesized to achieve antistatic finishing application for polyester fabrics. The test results indicated that some antistatic agents from this work had durable antistatic effect to polyester fabrics.
The waterborne polyurethane was also synthesized to achieve wrinkle-resistant application for pure cotton fabrics. The experimental results showed that the treated cotton fabrics have a remarkably increase in wrinkle-resistant behavior.
The waterborne polyurethane/clay nanocomposites were synthesized by intercalating organoclay. The clay was organically modified with the RF-751 swelling agent. The WAXD test results showed that the 2θvalue of the clay and organomodified clay are 7.88 and 4.7, respectively. The d-spacing of organomodified clay was increased to 0.76 nm, the result indicated the organic modification of the clay is successful and the clay is intercalated or exfoliated in waterborne polyurethane/clay nanocomposites. Thermal properties and mechanical propreties were characterized with TGA、DSC and tensile tester. The thermal properties and mechanical propreties were improved in some of the waterborne polyurethane/clay nanocomposites.
