摘要
为赋予织物多功能性,解决纳米材料在织物表面的分散均匀性问题,采用植酸与三聚氰胺制备植酸铵盐,赋予织物阻燃性能。在此基础上,阻燃织物表面原位生长纳米银,制备阻燃抗菌多功能纺织品。通过正交试验分析方法对织物阻燃整理和抗菌整理工艺进行优化,并通过红外光谱、扫描电镜、能谱、热重分析等技术手段对织物进行表征。研究结果表明:织物经植酸铵盐二浸二轧整理后,其极限氧指数可达35%以上,其耐水洗性能提高;对大肠杆菌和金黄色葡萄球菌有良好的抑菌作用;整理织物表面粗糙,含有P、N、Ag等元素,织物表面成功接枝植酸铵盐和Ag纳米颗粒,且分布均匀;植酸铵盐和植酸铵盐-Ag对织物表面形成炭层有一定影响,其燃烧后的炭渣量比未整理织物增加了27%。
In order to enable the fabrics with multi-functions and solve the problem of uniformity of nanomaterials on the surface of fabrics,ammonium phytate was synthesized from phytic acid and melamine,which were economically and environmentally friendly and hence widely used. The flame-retardant property of the fabric was endowed with ammonium phytate and in-situ growth of nano-silver on the surface of flame-retardant fabrics to prepare flame-retardant and anti-bacterial multi-functional textiles.The flame retardant and antimicrobial finishing processes of fabrics were optimized by orthogonal test analysis. The fabrics were characterized by infrared spectrum,scanning electron microscopy,energy dispersive spectroscopy and thermogravimetry. The results show that the limiting oxygen index of the fabric reaches more than 35% after two-dip and two-roll finishing with ammonium phytate salt,and the washing resistance of the fabric is shown possible to be improved. The flame-retardant fabrics have good bacteriostatic effect on Escherichia coli and Staphylococcus aureus by in situ growth of nano silver. The surface of the finished fabric became rough and contains P,N and Ag,which indicates that ammonium phytate and Ag nanoparticles uniformed distribution are successfully grafted on the surface of the fabric.Finishing agent( PA-N,PA-N-Ag) have a certain effect on the formation of carbon layer on the surface of fabrics,and the amount of charcoal slag after burning is 27% higher than that of the original fabrics.
