The development of novel flame retardants for cotton textiles that form a stable layer on textile fiber is of high economical and practical relevance. A novel flame retardant fluorinated phosphoric acid esters modified silicone resins for cotton modification were synthesized. The investigated phosphoric acid esters based compounds were substituted by a fluorinated chain or ring, and alkoxysilyl groups. The presence of alkoxysilyl groups allowed the formation of bonds with cellulose, while derivatives of phosphoric esters reduced the flammability of fabrics. Additionally, the presence of fluoride in their structures affected the hydrophobic properties. Cotton fabrics were modified in a simple one-step process by dip-coating method. The flame retardant properties of modified textiles were examined by performing microcalorimetric analysis, thermogravimetry analysis, and measuring oxygen index. The hydrophobicity was evaluated by measuring the water contact angle. The modified fabrics were characterized by SEM-EDS (Scanning Electron Microscopy with Energy Dispersive Spectroscopy) analysis and surface morphology. As a result of the tests, multifunctional fabrics were obtained.
开发能在纺织纤维上形成稳定涂层的新型棉织物阻燃剂具有很高的经济和实际意义。合成了一种用于棉织物改性的新型阻燃含氟磷酸酯改性有机硅树脂。所研究的基于磷酸酯的化合物被含氟链或环以及烷氧基甲硅烷基取代。烷氧基甲硅烷基的存在使得能够与纤维素形成键,而磷酸酯衍生物降低了织物的可燃性。此外,其结构中氟的存在影响了疏水性能。通过浸涂法在一个简单的一步过程中对棉织物进行改性。通过进行微量热分析、热重分析和测量氧指数来检测改性纺织品的阻燃性能。通过测量水接触角来评估疏水性。通过扫描电子显微镜-能谱分析(SEM-EDS)对改性织物的表面形态进行表征。测试结果得到了多功能织物。
