摘　　要：针对羊毛织物的传统染色及阻燃整理工艺流程复杂、条件苛刻、损伤织物并可能污染环境等问题,采用生物酶法,以没食子酸(GA)和9,10-二氢-9-氧杂-10-磷杂菲-10-氧化物(DOPO)为底物,通过漆酶催化作用,在温和条件下采用一步法在羊毛织物上同步实现染色和阻燃功能化。借助紫外-可见光谱仪、测色仪、氧指数仪、扫描电子显微镜、能量色散谱仪及红外光谱仪等对GA、DOPO、GA/DOPO混合物反应液及其处理后织物的形貌和化学组成进行测试与表征,对GA与DOPO及羊毛的反应机制进行分析,并对处理后织物的染色性能、阻燃性能、热稳定性、强力及手感性能等进行测试。结果表明:GA与DOPO之间能够发生共聚反应,并与羊毛通过接枝交联附着在羊毛织物表面,赋予其一定牢度的颜色与阻燃性能;经GA和DOPO共同处理后羊毛织物呈褐色,K/S值达到4.98,极限氧指数达到27.5%,织物强力较未处理羊毛提升46%左右,且处理得到的织物样品仍保持羊毛优良的手感。Objective Wool fabrics is widely used in apparel,upholstery and industrial applications due to properties such as comfort,biocompatibility,breathability,and hygroscopicity.Conventional dyeing methods for wool products require boiling at high temperatures,consuming large amounts of energy and chemicals,and exerting a detrimental effect on the fabric′s inherent properties.In addition,durable flame retardancy for wool fabrics are generally produced by baking phosphorus-containing compounds,usually in the presence of cross-linking agents,at high temperature,or by treating wool fabrics with metal complexes,such as potassium hexafluorotitanic,which lead to yellowing of the fabrics,damage to strength,and heavy metal problems.Consequently,the development of facile and eco-friendly dyeing and flame retardant methods for wool fabrics is essential.Method A laccase-catalyzed one-step process using gallic acid(GA)and 9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide(DOPO)as substrates was used to achieve simultaneous dyeing and flame retardant functionalization of wool fabrics.The reaction mechanism of GA and DOPO was analyzed with help of UV-visible spectrometer.The morphology,chemical composition,color and the flame retardancy of the treated fabrics were tested and characterized by means of scanning electron microscope,EDS,infrared spectrometer,colorimeter and oxygen index meter.Results The results demonstrated that the use of laccase as a catalyst enabled the grafting,cross-linking and absorption of GA and DOPO with wool,facilitating the in-situ dyeing and fire retardant modification of wool.The ultraviolet spectroscopy analysis and the color of the samples indicated that the copolymerization of DOPO and GA hinders the polymerization of GA,resulting in a weakened copolymerization and a lower K/S value for GA-DOPO-Wool in comparison to GA-Wool.The limit oxygen index and vertical burning tests demonstrated the effective flame retardant properties of the GA-DOPO-Wool.This phenomenon may be attributed to the reaction betwee
