    Abstract: 本研究主要係以純棉織物以奈米級　TiO2（二氧化鈦）複合銀粉，探討不同多元羧酸（BTCA、MA、SUA、CA）於紫外光作用下進行光催化反應，而獲致無甲醛之永久免燙棉織物。其中改變交鏈劑種類及濃度等條件進行加工，以充分瞭解棉織物經交鏈反應後對物性（防縐性、接枝率、接枝效率、強力、白度、柔軟度、永久免燙等級（DP Rating）、FTIR定性分析及SEM表觀分析）及染色性（K/S、染著量）之影響。由實驗結果顯示，四種交鏈劑中以BTCA具有較好的物性，且隨著交鏈劑濃度的提高，棉織物的防縐性、接枝率及柔軟度皆有增加的趨勢，但接枝效率、強力白度則呈輕微下降。在染色性方面，經交鏈後棉織物的K/S及染著量皆稍有提昇。至於複合交鏈劑以BTCA/CA莫耳比75/25時，可使棉織物有最好的防縐性，但強力、白度及DP Rating 有輕微降低。

    In this study, the non-formaldehyde crease-resist finishing of cotton fabrics using the polycarboxylic acid (BTCA、MA、SUA、CA) as cross-linking agent, and nanometer grade TiO2 compound Ag as catalyst under UV light reactive and has been investigated. The change of kinds and concentrations of cross-linking agents were studied and the effect of dry and wet wrinkle recovery angle, grafting yield (%), grafting efficiency (%), the strength rate of decrease (%), the whiteness rate of decrease (%), the softness rate of increase (%) and durable press rating were research. The result shows the effect of dry and wet wrinkle recovery angle, grafting yield (%) and the softness rate of increase (%) could increase with concentration of the cross-linking agents increase. Then grafting efficiency (%), the strength rate of decrease (%) and the whiteness rate of decrease (%) could decrease with the concentration of the cross-linking agents increase.
