摘要/Abstract

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。

Abstract:

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 againstEscherichia coli and Staphylococcus aureus were 99.05% and 95.52%, respectively, indicating good flame retardant and antibacterial property.

Key words: cotton-viscose blended fabrics, flame retardant finishing, antibacterial finishing, functional finishing, functional textiles
