与氟化和有机磷化合物有关的环境问题导致了对赋予纺织品阻燃性和拒水/拒油性的方法的考虑。介绍了一种简单易行的超疏水阻燃棉织物的制备方法。采用氨基功能化二氧化硅纳米粒子对环氧功能化棉进行复合包覆，并辅以氧化锌纳米粒子包覆。在这种情况下，新的制备技术被用来制备胺化二氧化硅和氧化锌纳米粒子。使用透射电子显微镜（TEM）研究了粒径，并使用FT-IR分析和其他分析技术研究了化学结构。采用甲基丙烯酸缩水甘油酯（GMA）和丙烯酸（AA）的混合物组成的纳米乳液接枝棉纤维，使棉纤维表面发生环氧和羧基功能化，然后采用传统的轧-干-焙整理方法对棉纤维进行功能化整理。经处理的织物显示出良好的拒水性和优异的阻燃性能，如通过标准测试方法所测定的。
Environmental concerns related to fluorinated and organophosphorus compounds led to a consideration of the methods for imparting flame retardancy and water/oil repellency to textiles. A simple and facile method for fabricating the cotton fabric with superhydrophobicity and flame retardancy is described in the present work. Complex coating with amino-functionalized silica nano-particles on epoxy-functionalized cotton accompanied with ZnO nano-particles coating are carried out. In This context, new preparation techniques were used to prepare both aminated silica and ZnO nano-particles. The particle size was investigated using Transition Electron Microscope (TEM) and the chemical structure was investigated using FT-IR analysis and other analytical techniques. Cotton was functionalized with epoxy and carboxyl via grafting cotton with nano-emulsion consisted of mixture of glycidyl methacrylate (GMA) and acrylic acid (AA), and then treated for functional finishing through conventional pad-dry-cure method. The treated fabrics showed good water repellency and excellent flame retardant properties as determined by the standard test methods.
