This work aims to prepare a series of sols based on Titanium (IV) butoxide (TBT) and using boric acid as a functional additive. The sols were applied onto the cotton fabric by the pad-pry-cure process. The as-obtained cotton fabrics were characterized using Fourier-transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM) analysis in order to determine their chemical composition and their surface morphology, respectively. The results indicate the formation of TiO₂–boron-based coating over the surface of coated cotton fabric. X-ray diffraction (XRD) patterns showed that the coating did not affect the crystallographic structure of the cellulosic fabric. The functional properties of the treated samples were measured from thermo-oxidative stability and burning behavior performance, drop absorption and water uptake measurements. The results showed that the coated cotton fabrics by the sol–gel approach through the application of TiO₂–boron-based coating with 2.5 molar ratio of boric acid possessed high thermal stability and flame retardancy. Most importantly, a total burning time of 2 s and a residue of more than 90% were obtained after 10 s of flame application, indicating that the functionalized cotton fabric self-extinguished the fire rapidly. The water-repellent properties were also enhanced and the obtained results mentioned that the drop time and the water uptake were improved compared with untreated cotton fabric. The effect of the application of TiO₂–boron-based coatings on the mechanical properties of cotton samples, as well as their washing fastness were studied.

这项工作旨在制备一系列基于丁酸钛（IV）（TBT）并使用硼酸作为功能性添加剂的溶胶。溶胶通过垫式固化过程被施加到棉织物上。使用傅立叶变换红外（FTIR）光谱和扫描电子显微镜（SEM）分析对所获得的棉织物进行表征，以分别测定其化学组成和表面形态。结果表明TiO ₂的形成–在涂层棉织物表面上的硼基涂层。X射线衍射（XRD）图表明该涂层不影响纤维素织物的晶体结构。通过热氧化稳定性和燃烧行为性能，液滴吸收和吸水率测量来测量处理样品的功能特性。结果表明，采用TiO ₂溶胶-凝胶法涂覆棉织物硼酸摩尔比为2.5的基于硼的涂料具有很高的热稳定性和阻燃性。最重要的是，在施加火焰10 s后，总燃烧时间为2 s，残留物超过90％，这表明功能化棉织物能迅速自熄。疏水性也得到增强，并且获得的结果提到与未处理的棉织物相比，下降时间和吸水率得到改善。研究了TiO _2-硼基涂料的应用对棉花样品的机械性能及其耐洗牢度的影响。
