摘　　要：采用溶胶-凝胶法制备纳米二氧化钛及其整理剂,通过浸—轧工艺将其用于棉织物的抗紫外线整理。用扫描电镜对制得的纳米二氧化钛粒子及整理前、后织物的表面进行了观察,同时测定了整理织物的抗紫外线性能。结果表明,整理后的织物具有优异而耐久的抗紫外线效果,其UPF≥50;UPF值随整理液中二氧化钛的增加而升高;经50次洗涤后,UPF值仍保持在较高的水平,且织物的白度、手感等性能较好。Nano-titanium dioxide was prepared by sol-gel method. And the finishing agent containing nano-titanium dioxide was used as anti-ultraviolet finishing agent for cotton fabric by dip padding techniques. Scanning electron microscopy was used to observe the morphology of nano-titanium dioxide particles and the surfaces of untreated / treated cotton fabrics. The anti-ultraviolet property of the treated fabrics was tested. The results showed that the treated fabrics have excellent and durable UV protection properties, with UPF≥ 50. The UPF values increased with increase of the concentration of nano - titanium dioxide. And after home launderings, the UPF still maintained at a high level. Also, the whiteness and handle of the treated fabrics were kept good.
