    摘要: 本實驗主要是將純棉織物以奈米級二氧化鈦(TiO2)爲催化劑，並以不同多元羧酸溶液爲交鏈劑經二浸二壓及預乾後，用紫外光崔化以制作無甲醛防縐加工物。所使用的多元羧酸交鏈劑包括：琥珀酸，檸檬酸，馬來酸酐，1,2,3,4-丁烷四羧酸。本研究探討不同交鏈劑濃度、催化劑濃度和紫外光照時間對棉織物防縐性和物性的影響。由結果顯示棉織物之乾縐摺回復角、濕縐摺回復角接枝率隨交鏈劑濃度、催化劑濃度以及光照時間之增加而增加，而催化劑濃度超過0.8%或光照時間大於30分鐘後有下降的趨勢；但是強力、白度、柔軟度則相反。其中1,2,3,4-丁烷四羧酸交鏈劑加工織物有較佳之防趨性和柔軟度，同時具有良好的接枝率、接枝效率與白度等性質。與傳統樹脂加工物相比，雖防縐性不如傳統樹脂加工物，但強力、白度、柔軟度皆較傳統樹脂加工物佳，尤其在強力方面更甚。

    This research mainly treats cotton fabric with solution, which is composed of nanoparticles of TiO2 photocatalyst and different polycarboxylic acids, and prepared by two dips-two-nips, pre-drying and photocatalyzed by UV irradiation to produce non-formaldehyde crease resistant fabric. We have compared several kinds polycarboxylic acids, including succinic acid (SUA), citric acid (CA), maleic anhydride (MA) and 1,2,3,4-butene tetracarboxylic acid (BTCA) for crosslinking agents. The influence of the acid concentration, catalyst additive level and UV irradiation time on crease-resist and physical properties were investigated. The experimental results indicate that for both dry and wet wrinkle recovery angle, graft ratio increases with crosslinking agent concentration, catalyst additive level and UV irradiation time. However, it showed a decreasing trend when the catalyst addition was over 0.8% or irradiated under UV light over 30 minutes. But the strength, softness and the whiteness of the treated Cotton fabric showed reversed results. Among these polycarboxylic acids, 1,2,3,4-butene tetracarboxylic acid performed best for both dry and wet wrinkle recovery angles, in terms of softness, graft ratio and whiteness compared with a traditional dimethylol-dihydroxyethylene urea (DMDHEU) finish, it has better strength, whiteness, and softness, although it doesn't have as good crease resistance as the traditional ones.
