    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
    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.
