摘要

本研究只要是以純棉織物以不同粒徑的二氣化鈦(TiO2)催化劑和多元羧酸交鍊劑經過二浸二壓及預乾後，再以紫外光來進行光催化以製造無甲醛抗縐加工物。其中多元羧酸有：琥珀酸(SUA)、1,2,3,4-丁烷四羧酸(BTCA)、馬來酸(MA)、檸檬酸(CA)。其改變不同粒徑的二氣化鈦催化劑後，再來探討經處理後之物化性。由實驗結果顯示，四種不同粒徑的二氣化鈦催化劑中以10nm和20nm可使棉織物獲得良好的物化性。棉織物的防縐性、柔軟度、接枝率及接枝效率皆有增加的趨勢，但強力及白度則呈現下降，所以可以說當棉識物加工到達奈米級，物化性都可以到達不錯的效果。

In the study, cotton fabric was treated by solution, which is composed with different sizes of TiO2 and different polycarboxylic acids. There are different polycarboxylic acid, including succinic acid, citric acid, maleic anhydride and 1, 2, 3, 4-butene tetracarboxylic acid. Cotton fabrics were treated by 4 different sizes Ti02 particles and, the result shows that l0nm and 20nm TiO2 particles treated cotton fabrics have better physical and chemical properties. The recovery angle, softness, graft ratio and graft effect ratio can be increased, but the strength and whiteness can be not increased. When the cotton fabric finishing is nano titanium, it's physical and chemical effect are better.
