Abstract

Cotton (CO) fabrics with flame retardant properties based on ionic liquids: 1-methyl-3-(-((triethoxysilyl)oxy)propyl)-1H-imidazol-3-ium chloride (MCPTS) and 1-(3-(triethoxysilyl)propyl)pyridine-1-ium chloride (PCPTS) with boron from boric acid are successfully obtained via a sol-gel process. Fourier transform infrared spectroscopy (FTIR), optical microscopy analysis, and scanning electron microscopy (SEM) images, were first carried out to characterize the chemical composition and the morphology of the treated and untreated cotton fabrics, respectively. The investigation of flame resistance was evaluated by the vertical burning test. It was observed that the treated cotton fabrics exhibited good flame-retardant properties and did not burn even after 10 s flame application duration and the rate of flame spread was inhibited compared to the pristine cotton fabric. Furthermore, the thermal comportment of cotton fabrics was analyzed by thermogravimetric (TG) analysis and differential scanning calorimeter (DSC). Moreover, the tensile strength of the treated textiles is mostly reserved. In this work, we prove that the sol-gel method using ionic liquids and boron could be used as an effective flame retardant to develop finishing cotton fabrics for textile fireproof applications.

溶胶-凝胶法制备含硼离子液体化合物对棉织物的阻燃整理

采用溶胶-凝胶法制备了1-甲基-3-((三乙基氧基)丙基)- 1h -咪唑-3-氯化铵(MCPTS)和1-(3-(三乙基氧基)丙基)吡啶-1-氯化铵(PCPTS)离子液体，硼酸中含有硼，具有阻燃性能的棉织物。傅里叶变换红外光谱(FTIR)、光学显微镜分析和扫描电子显微镜(SEM)图像，分别表征了处理和未处理棉织物的化学成分和形态。通过垂直燃烧试验对其阻燃性能进行了评价。实验结果表明，处理后的棉织物具有良好的阻燃性能，与未处理的棉织物相比，即使在火焰持续10 s后仍不燃烧，火焰的蔓延速度也受到抑制。采用热重分析(TG)和差示扫描量热仪(DSC)分析了棉织物的热性能。此外，处理后的纺织品的抗拉强度大多保留。在本工作中，我们证明了离子液体和硼的溶胶-凝胶法可以作为一种有效的阻燃剂来开发用于纺织防火的后整理棉织物。图形抽象
