摘要: 为将纳米粒子应用于织物的功能整理,采用溶胶-凝胶法制备了锆纳米溶胶,利用浸轧法将溶胶整理到涤纶织物上,烘焙后在织物表面形成了一层二氧化锆纳米颗粒。分析反应物浓度、水解促进剂的种类和用量等条件对产物粒径的影响,得到制备锆纳米溶胶的最佳反应条件:反应物浓度0.10mol/L,以双氧水为水解促进剂,用量为m(双氧水):m(ZrCl4)=1:1。最佳条件下制备的锆溶胶平均粒径约为60nm。涤纶织物经ZrO2溶胶整理后,其防护系数(UPF)从86提高到185(150℃烘焙处理),在长波紫外线(UVA)区域紫外透过率明显降低,经50次水洗后UPF值仍能保持在132,抗紫外性能具有一定的耐水洗性。

Abstract: For applying nano-particles to the functional finishing of textiles, Nano-ZrO2 sol was prepared by sol-gel method, and the PET fabrics was treated with the ZrO2 sol by dip-padding process. A thin layer of nano-ZrO2 particles was formed onto the surface of the fabrics after been cured. The effects of concentration of reactant, kind of hydrolysis promoter and the ratio of reactant and hydrolysis promoter to the particle size of ZrO2 sol were analyzed, and the optimal reaction conditions for preparing nano-ZrO2 sol were determined as follows: concentration of the reactant 0.10mol/L, oxydol as hydrolysis promoter, quality ratio of oxydol to ZrCl4 1:1. ZrO2 sol with about 60nm in diameter was obtained in optimal reaction conditions. The ultraviolet protection factor (UPF) of the treated PET fabrics reaches 185 from 86(cured at 150℃), which has a much lower ultraviolet ray transmission in UVA. The standard test to washing (soaping) showed that the UPF value still remains 132 after 50 washing cycles. The experimental results showed that the treated PET fabrics possess durable UV-resistance property.
