摘　　要：针对棉织物易燃烧、易为有害细菌的滋生提供适宜生长环境,给人们正常生活带来重大安全隐患和健康危害等问题,采用γ-脲基丙基三乙氧基硅烷(TESPR)和苯基膦酸(PPOA),通过溶胶-凝胶法制备了阻燃抗菌棉织物。借助扫描电子显微镜、热重分析仪、锥型量热测试仪、万能材料试验机、织物透气仪等对制得的阻燃棉织物进行表征,研究了其阻燃性能、热稳定性能、力学性能、抗菌性能以及透气性能等。结果表明:TESPR/PPOA成功附着于棉织物表面,极限氧指数达到27.2%;TESPR/PPOA涂层阻燃整理棉织物初始热降解温度低于未处理棉织物,但高温区的残炭量增加,表明在低温区生成的残炭能够作为隔热屏障保护内部棉织物;此外,TESPR/PPOA在棉织物表面的沉积,在大幅度提升抗菌性能的同时,保留了较好的透气性。Objective Cotton fabrics are extensively utilized for their softness and wearing comfort,but the flammability is a significant drawback.Reports indicate that the human casualties and financial losses caused by fires related to cotton fabrics are unimaginably high every year.Therefore,it is crucial to improve the flame-retardancy of cotton fabrics.Unfortunately,the most widely used halogen-containing flame retardants face restrictions due to the production of halogenated hydrocarbons when burned.In addition,cotton fabrics with a single flame-retardant function are no longer sufficient to meet normal application needs,and customers demand that flame-retardant cotton fabrics would also possess functions such as waterproofing,antibacterial properties,and UV resistance.Consequently,the development of additives to enhance the flame retardancy and antibacterial functions for cotton fabrics is essential.Methodγ-urea-propyltriethoxysilane(TESPR)and phenylphosphonic acid(PPOA)were utilized in the preparation of flame-retardant cotton fabrics using the sol-gel technique.The flame-retardant cotton fabrics were subsequently analyzed using various techniques,including scanning electron microscopy,thermogravimetric analysis,vertical flame test,cone calorimetry test,antibacterial activities,universal material testing machine,and fabric air permeability testing.Results The results indicated that the TESPR-PPOA coating was successfully deposited on the surface of cotton fabrics.The thermogravimetric analysis revealed that although the initial thermal degradation temperature of TESPR/PPOA flame retardant cotton fabrics was lower compared with that of cotton fabrics,the char residues in the high-temperature zone were increased.Moreover,TESPR/PPOA flame retardant cotton fabrics was able to succeed a rapid self-extinguishment after the igniter was removed,with the afterflame time and the afterglow time being reduced to 0 s.Meanwhile,the damaged length of TESPR/PPOA flame retardant cotton fabrics obtained from vertical flame test was
