A new approach for flame retardant functional finishing of textiles was explored to improve flame retardancy of cotton fabrics by simple physical adhesion method. Mg(OH) was adhered to cotton fiber with the aid of fiber swelling in ionic liquid on heating and shrinkage on washing to obtain flame retardancy. The effects of immobilizing condition and methods on flame retardancy were discussed. The surface morphology, crystal structure, combustion behavior, thermal and physical properties of cotton fabric adhered with Mg(OH) were analyzed. The afterflame time and afterglow time of adhered cotton fabric were significantly reduced to less than 5 s. The thermal weight loss of cotton fabric was increased by 11.7% and the total heat released per unit mass was decreased by 20.9% after MH adhesion. The simple eco-friendly adhesion method provided a convenient approach for the development and application of flame retardant functional cellulosic textiles.
探索了一种用于纺织品阻燃功能整理的新方法，通过简单的物理粘附方法提高棉织物的阻燃性。借助离子液体中纤维在加热时的膨胀和洗涤时的收缩，将Mg(OH)附着在棉纤维上以获得阻燃性。讨论了固定条件和方法对阻燃性的影响。分析了附着Mg(OH)的棉织物的表面形态、晶体结构、燃烧行为、热性能和物理性能。附着棉织物的续燃时间和阴燃时间显著降低至小于5秒。附着Mg(OH)后，棉织物的热失重增加了11.7%，单位质量的总热释放量降低了20.9%。这种简单的环保粘附方法为阻燃功能性纤维素纺织品的开发和应用提供了一种便捷途径。
