摘要/Abstract

摘要：

为制备具有拒水、拒油、抗紫外线功能的涤纶织物,以钛酸四丁酯为前驱体,采用溶胶-水热法在涤纶织物表面原位生成纳米TiO₂,然后采用氟硅烷(1H,1H,2H,2H-全氟辛基三乙氧基硅烷)对其进行低表面能修饰。分析了涤纶表面形貌、结晶结构和表面化学成分、表面润湿性能的变化,并对修饰后织物的拒油等级和抗紫外线性能进行测试。结果表明:整理后涤纶织物表面生成锐钛矿型TiO₂,氟硅烷均匀沉积在纤维表面;TiO₂-氟硅烷联合整理后涤纶织物的拒水拒油性能显著提升,其表面水接触角达153°,拒油等级达到6级;对紫外线A段和B段的平均透光率分别下降至0.37%和0.01%。

Abstract:

In order to develop polyester fabrics with water repellent, antifouling and ultraviolet resistant properties, nano-titania was formed in-situ on the polyester fabric surface by sol-hydrothermal method using tetrabutyl titanate as precursor, and then subjected to low surface energy modification by fluorosi-lane (1H,1H,2H,2H-perfluorooctyltriethoxysilane). The surface morphology, crystalline structure, surface chemical composition and surface wettability of polyester fabrics were analyzed, and the oil resistance and ultraviolet resistance of the treated polyester fabrics were tested. The results show that anatase phase titania is formed in-situ on the surface of polyester fabric, and fluorosilane is uniformly deposited on the fibers after the treatment. The water-repellent and oil-repellent properties of polyester fabrics treated with titania-fluorosilane are significantly improved. The surface water contact angle reaches 153°, and the oil-repellent grade reaches 6 grades. The average ultraviolet transmittance of ultraviolet A and ultraviolet B segments decreases to 0.37% and 0.01%, respectively.

Key words: TiO₂, polyester fabric, fluorosilane, superhydrophobicity property, ultraviolet resistance, functional textiles
