Abstract

The traditional fluorine-containing finishing agents used for anti-fouling textiles not only cause serious environmental and health hazards, but also have the problem of insufficient fabric durability. Therefore, bio-based slippery finishing agents have great application prospects for textile finishing. In this paper, cellulose nanocrystal was thiol-modified with 3-mercaptopropyltriethoxysilane and then compounded with bisphenol A diglycidyl ether and amino-terminated double-end-capped polydimethylsiloxane. The cotton fabric surface was modified via a padding–drying–curing process. The amino-terminated double-end-capped polydimethylsiloxane endowed the coating with low-surface energy, which synergized with the dense micro/nanoscale rough structure formed by the modified cellulose to achieve slippery and anti-fouling functionalities. The surface morphology, chemical structure, and elemental distribution of the fabric were characterized, and its sliding performance, anti-fouling property, and water/oil repellency were tested. The results demonstrated that the cotton fabric modified with the bio-based fluorine-free slippery coating exhibited a sliding angle < 10°, enabling facile liquid movement and removal while possessing excellent water and oil repellency and environmental compatibility.

生物基无氟滑棉织物及其耐久防污性能研究

传统的含氟织物防污整理剂不仅对环境和健康造成严重危害，而且存在织物耐久性不足的问题。因此，生物基湿性整理剂在纺织品整理中具有广阔的应用前景。本文采用3-巯基丙基三乙氧基硅烷对纤维素纳米晶进行巯基改性，然后与双酚A二缩水甘油酯醚和氨基端双端盖聚二甲基硅氧烷复配。采用填充-干燥-固化工艺对棉织物表面进行改性。氨基端双端盖帽聚二甲基硅氧烷赋予涂层低表面能，与改性纤维素形成的致密微纳米级粗糙结构协同作用，获得光滑和防污功能。对织物的表面形貌、化学结构和元素分布进行了表征，并对织物的滑动性能、防污性能和拒水拒油性能进行了测试。结果表明，生物基无氟光滑涂层改性后的棉织物具有10°的滑动角，有利于液体的移动和去除，同时具有良好的拒水拒油性和环境相容性。图形抽象
