摘　　要：为获得阻燃和抗菌复合功能的纺织品,合成了一种梳状硅-磷-氮协效阻燃抗菌整理剂,并对棉/粘胶混纺织物进行功能整理;通过单因素实验对棉/粘胶混纺织物的整理工艺进行优化,得到最佳整理工艺:阻燃抗菌整理剂质量浓度为500 g/L,2-膦酸基丁烷-1,2,4-三羧酸质量浓度为150 g/L,在50℃浸渍40 min后二浸二轧,70℃预烘5 min,130℃焙烘150 s。借助红外光谱仪、垂直法阻燃性能测试仪、数显氧指数仪、扫描电子显微镜、能量色散X射线光谱仪、热重分析仪等对织物的结构和性能进行分析。结果表明:整理后棉/粘胶混纺织物的极限氧指数可稳定保持在28%以上,阴燃时间、续燃时间均为0 s,织物燃烧后表面富集Si、P、N元素的致密的炭层,在800℃时的残炭量为40.16%;整理后棉/粘胶混纺织物与未整理织物相比,对于大肠杆菌和金黄色葡萄球菌的抑菌率分别为99.05%和95.52%,该织物具有较好的阻燃抗菌性能。In order to obtain both flame retardant and antibacterial properties for textiles,the composite functional agent for cotton-viscose blended fabrics was synthesized from comb-like silicon-phosphor-nitrogen synergistic flame retardant-antibacterial agent.The treatment process of cotton-viscose blended fabrics was optimized through single factor experiment,and fabric structure and performance were analyzed using infrared spectrometer,vertical combustion instrument,limit oxygen index(LOI)tester,scanning electron microscope,energy dispersive X-ray spectrometer,thermogravimetric analysis,and so on.The results show that the optimal processing parameters are 500 g/L flame retardant antibacterial agent and 150 g/L 2-phosphonobutane-1,2,4-tricarboxylic acid(PBTCA),soaking at 50℃for 40 min,two dip and two roll,pre-drying at 70℃for 5 min,and curing at 130℃for 150 s.The LOI value of the treated cotton-viscose blended fabrics was above 28%,and the after-flame time and after-glow time were both 0 s.The dense carbon layer with Si,P and N elements enriched on the surface of the fabrics after combustion was 40.16%at 800℃.The antibacterial rates of treated cotton-viscose blended fabrics against Escherichia coli and Staphylococcus aureus were 99.05%and 95.52%,respectively,indicating good flame retardant and antibacterial property.
