腈纶织物的氰基水解酶/硼酸锌阻燃整理

为提高腈纶织物的阻燃性能，采用氰基水解酶对腈纶织物进行预处理，再用硼酸锌对腈纶织物进行阻燃整理。通过X射线光电子能谱（XPS）、热重分析（TG）、Zeta电位测试、增重率测试及限氧指数（LOI值）分析，研究了氰基水解酶-硼酸锌整理后腈纶织物的阻燃性能。研究结果表明：酶处理能促进硼酸锌阻燃剂在腈纶纤维上的吸附与结合，从而进一步提高腈纶织物的阻燃性能。与单独阻燃剂整理的腈纶织物相比，酶预处理后再阻燃整理织物的增重率提高了4.9%，LOI值提高了10.3%，腈纶织物的限氧指数能达到27.8%。

Flame retardant finishing of acrylic fabric using nitrilase/zinc borate

In order to improve its flame retardant properties, acrylic fabric was pretreated with nitrilase, followed by zinc borate flame retardant finishing in order to improve its flame retardant properties. The enhancement of flame retardant property was studied by X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TG), Zeta potential measurement, weight gain rate and limiting oxygen index (LOI). The results showed that enzymatic pretreatment efficiently improve the adsorption and combination of zinc Borate on acrylic fibers. So the flame retardant property of acrylic fabric further improved. The weight gain rate and LOI value of nitrilase/zinc borate treated sample increased respectively 4.9% and 10.3% compaired with zinc borate treated sample. The limiting oxygen index of the treated sample increased to 27.8%.
