采用聚乙烯醇(PVA) -丙烯酸（AAc）水溶液25μm表面涂层的方法，对棉、棉/涤混纺、尼龙-6等不同纺织织物进行了改性研究。采用恒定剂量50kGy的电子束辐照完成表面涂层的辐射固化。考察了交联剂的存在与否和涂层溶液中AAc的浓度对固化涂层织物亲水性的影响。与亲水性有关的性质，特别是吸水性和减重，在几个洗涤循环前后进行了跟踪。确定折痕恢复角。尼龙-6溶液中AAc含量越高，吸水率和折痕恢复角越明显，混纺次之，棉次之。另外，对涂层织物的染色性能进行了研究。% AAc，用色差法对碱性和活性染料进行了测试。颜色强度得到了相对的提高。涂布液中交联剂的存在对染色性能的影响尤为显著。通过扫描电镜（SEM）观察涂层织物的形貌，表明涂层与织物的牢度和相容性。给出了结构与所得结果的相关性。
A study has been made to modify different textile fabrics such as cotton, cotton/polyester blend and nylon-6 fabrics by surface coating with a constant thickness layer of 25μm of aqueous solution of polyvinyl alcohol (PVA) and acrylic acid (AAc). Radiation curing of surface coating was accomplished by electron beam irradiation with a constant dose of 50kGy. Parameters affecting hydrophilicity of cured coated fabrics, namely, presence or absence of cross-linking agent and concentration of AAc in coating solution, were investigated. Properties affiliated with hydrophilicity, specifically water uptake and weight loss, before and after several washing cycles were followed up. Crease recovery angle was determined. Considerable enhancement, in water uptake as well as crease recovery angle, has been attained with increasing AAc content in solution in case of nylon-6, followed by blends and then cotton. Moreover, dyeing properties for coated fabrics, with solution containing 4wt.% AAc, has been tested by color difference method, for basic and reactive dyes. Relative increase in color strength has been achieved. The presence of cross-linking agent in coating solution played a significant role, specifically in case of dyeing properties. Morphology of coated fabrics was examined by scanning electron microscope (SEM), which indicated fastness and compatibility between coating and fabrics. Correlation between structure and obtained results was given.
