摘要

本研究是以溶凝膠的方法將含有R側鏈基團之環氧基矽烷(GOTMS)與鈦酸丁酯(TTB)互相作用，並在催化劑下發生水解和聚縮合反應製成溶凝膠，其中主要改變環氧基矽烷(GOTMS)的濃度或鈦酸丁酯(TTB)的濃度，然後製成加工液，對棉織物進行熱處加工，最後再以多元羧酸進行後加工熱處，以探討不同加工條件對棉織物加工之影響，分別進行電子顯微鏡(SEM)、紅外線光譜儀(FT-IR)、熱差重力分析儀(TGA)、能量分散光譜儀 (EDS)分析及對物性之分析。由實驗結果發現：從掃描式電子顯微鏡(SEM)表面觀察及EDS分析，可以發現溶凝膠對棉織物能有效的附著結合，加工棉織物之熱裂解溫度皆比原胚棉織物低，加工棉織物具有抗菌效果，不具抗紫外線，具有耐洗滌性，棉織物經GOTMS與纖維網狀結合後，使織物變硬，柔軟性隨GOTMS含量增加而變差，抗皺程度會因溶凝膠而增大，但皆比原棉織物抗皺度還要好。

3-Glycidoxypropyl-trimethoxy silane (GOTMS) with alkyl side groups was reacted with titanium (IV) n-butoxide (TTB) by means of sol-gel method. The catalyst was applied in this reaction to accelerate the hydrolysis and the polycondensation processes and to obtain the colloidal dispersions. The parameters in these dispersions are the concentrations of GOTMS and TTB applied throughout the reactions. Cotton fabrics were firstly subjected to curing treatment using the colloidal dispersions, and then to post-finishing treatment using polycarboxylic acid. Scanning electron microscopy (SEM) with energy dispersion spectrum (EDS), Fourier-transform infrared spectroscopy (FT-IR), and thermogravimetric analyzer (TGA) were applied in this study to estimate the effects of the colloidal dispersions on the physical properties of the treated cotton fabrics. The SEM observations show that the adhesive bonding between the cotton fabrics and the sol-gel reagent is substantially effective. The thermo-decomposition temperatures for the sol-gel treated cotton fabrics are all lower than those of the untreated counterparts. Moreover, the sol-gel process would impart the effects of anti-bacteria, non-UV resistance, and washing resistance to the cotton fabrics. It is revealed that the cotton fabrics would become stiff after the sol-gel process due to the crosslinkage between the cotton substrate and the GOTMS. The softness of the cotton fabrics will decrease with increasing concentrations of GOTMS. Furthermore, the wrinkle resistance of the cotton fabrics after the sol-gel process will be superior to that of the untreated counterpart, and increase with increasing concentrations of the colloidal dispersions.
