Wool and wool-polyamide blended yarns (88.6% wool–11.4% polyamide 6,6 and 78.5% wool–21.5% polyamide 6,6) were knitted and the produced fabrics were treated by exhaustion method with zirconium complexes. Six different baths containing potassium hexafluorozirconate and zirconium acetate were studied. The flammability hazard was evaluated considering parameters such as the spread of flame, the heat release and the smoke release rate. Regardless of the blend composition, the untreated fabrics could not pass the vertical flammability test. 100% wool fabric could pass the vertical flammability test when treated with only 1% potassium hexafluorozirconate and 10% zirconium acetate solution. Higher compositions of metal complexes were required for the blended fabrics to pass the vertical flammability test. In the cone calorimeter test, 100% wool treated with 5% potassium hexafluorozirconate and 10% zirconium acetate solution gave the lowest peak heat release and smoke release rate values as 146.4 kW/m2 and 1.2 s−1, respectively.

羊毛和富羊毛混纺的阻燃处理:浴液成分研究

针织羊毛和羊毛-聚酰胺混纺纱线(88.6% 羊毛–11.4% 聚酰胺 6,6 和 78.5% 羊毛–21.5% 聚酰胺 6,6),并用锆络合物用尽染法处理生产的织物。研究了六种不同的含六氟锆酸钾和醋酸锆的镀液。考虑火焰蔓延、热释放和烟雾释放率等参数来评估可燃性危害。无论混合成分如何,未经处理的织物都无法通过垂直可燃性测试。100% 羊毛织物在仅用 1% 六氟锆酸钾和 10% 醋酸锆溶液处理时可以通过垂直可燃性测试。混纺织物需要更高的金属络合物成分才能通过垂直可燃性测试。在锥形量热仪测试中,
