摘　　要：针对机织羊毛织物阻燃环保性要求,以生物质植酸(PA)和羽毛角蛋白(FK)为原料,三元黏合剂[P(GMA-co-FHBMA)-g-PEGMA]为交联剂,基于浸轧-焙烘工艺,在机织羊毛织物表面构建了PA/P(GMAco-FHBMA)-g-PEGMA/FK阻燃涂层。采用FTIR、SEM、极限氧指数(LOI)、TG对阻燃整理前后机织羊毛织物进行了结构表征和性能测试。结果表明,采用浸轧-焙烘工艺在机织羊毛织物上成功构建PA/P(GMAco-FHBMA)-g-PEGMA/FK阻燃涂层。经过PA/P(GMA-co-FHBMA)-g-PEGMA/FK阻燃整理后的机织羊毛织物(C-3)的LOI可达32.5%±0.2%,损毁长度为96mm,续燃时间比未整理的机织羊毛织物的低。PA/P(GMAco-FHBMA)-g-PEGMA/FK阻燃涂层的引入对机织羊毛织物的断裂强力和手感影响较小,提高了机织羊毛织物的热稳定性,并形成稳定的炭层。经15次水洗,整理后的机织羊毛织物的LOI为27.3%±0.2%,表现出较好的耐久性。In order to meet the requirements of flame retardant and environmental protection of woven wool fabrics, biomass phytic acid(PA) and feather keratin(FK) as well as ternary adhesive [P(GMA-coFHBMA)-g-PEGMA] were used as raw materials and crosslinking agent to construct PA/P(GMA-coFHBMA)-g-PEGMA/FK flame retardant coating on the surface of woven wool fabric by a process of dip rolling and baking. The structure and properties of woven wool fabrics before and after flame retardant finishing were characterized and measured by FTIR, SEM, limiting oxygen index(LOI) and TG. The results showed that PA/P(GMA-co-FHBMA)-g-PEGMA/FK flame retardant coating was successfully constructed on woven wool fabric by the process of dip rolling and baking. The LOI of the woven wool fabric(C-3)after PA/P(GMA-co-FHBMA)-g-PEGMA/FK flame retardant finishing could reach 32.5%±0.2%, the damage length was 96 mm, and after-flame time were shorter than those of unfinished woven wool fabric.The introduction of PA/P(GMA-co-FHBMA)-g-PEGMA/FK flame retardant coating had little influence on the breaking strength and hand feel of the fabric, and could improve the thermal stability of the woven wool fabric and form stable carbon layer. After 15 times of washing, the LOI of the finished woven wool fabric was 27.3%±0.2%, showing better durability.
