    Abstract: 本論文首先以聚乙二醇（Polyethylene glycols-2000，PEG-2000）、2,2-二羥甲基丙酸（Dimethylol propanic Acid，DMPA）、異佛酮二異氰酸酯 ( Isophorone diisocyanate，IPDI )合成以NCO為末端之親水性PU寡聚物，並加入3-(丙烯醯基氧基)-2-羥基丙基甲基丙烯酸酯（3-acryloyloxy-2-hydroxypropyl Methacrylate
    ，AHM）形成紫外光硬化型寡聚物。以TEA中和DMPA所提供之COOH並分散至水相中，再加入奈米二氧化矽/二氧化鈦粒子，形成紫外光硬化型親水性水性ＰＵ樹脂。此水性PU可進行常溫架橋（以TMPTA-AZ進行開環反應）和紫外光架橋（添加光起始劑和反應稀釋劑進行紫外光交聯硬化反應）。將織物含浸塗佈於紫外光硬化型親水性水性PU樹脂，再經紫外光硬化處理乾燥，其中有兩個架橋反應：1.COOH與TMPTA-AZ進行開環反應2.末端為雙鍵之PU與活性稀釋劑進行紫外光硬化交聯反應。最後在織物上形成互穿式網狀交聯(IPN)，嵌入織物纖維中，最後經AATCC-135標準水洗測試進行30次耐水洗。利用此PU樹脂製備親水性織物，並由常溫架橋以及紫外光硬化的兩種雙重架橋達到快速且有效的方法來提升織物親水長效性。
    Hydrophilic NCO-terminated PU oligomer is obtained from hydrophilic polyethylene glycols-2000(PEG-2000)and dimethylolpropanic acid(DMPA)
    with isophorone diisocyanate(IPDI). It is reacted further with 3-acryloloxy -2-hydropropyl methacrylate (AHM) and forming UV-curable hydrophilic PU oligomer. DMPA offers COOH hydrophilic center.SiO2/TiO2 hybrids can be formulated within hydrophilic PU oligomers (in situ) before water dispersion. It is dispersed into water phase after neutralized with triethyl amine (TEA) as an aqueous-based dispersion UV-curable hydrophilic PU. This aqueous-based PU includes both thermal curing agent (TMPTA-AZ for ring-opening reaction) and UV-curing recipes (photo-initiator and reactive diluents).
    Hydrophobic PET textile is treated with aqueous-based dispersion of UV-curable resin and UV-cured with after dry.There are two different curing reactions with this hydrophilic PU coating material taking place: 1. COOH reacts withTMPTA-AZvia a ring-opening reaction.2.UV-curing of acrylated terminal groups PU and reactive diluents.The final cured hydrophilic PU forms inter-penetrating networks (IPN) with PET textile and it results water washing durable hydrophilic textile treatments after 30 washing cycles according to AATCC-135 method.
    The hydrophilic textile treated with this prepared PU resin,it demonstrate
    a quick and efficient method to improve the long lasting textile hyrophilicity
    by thermal and UV-curing dual processes.
