摘　　要：探索婴童纺织品中可迁移性荧光增白剂的定性测试方法,并研究其迁移规律和影响因素。模拟婴幼儿贴身内衣穿着过程中出汗、流口水及洗澡等状态,设计浸泡和贴合两种试验方法。选取萃取液、萃取时间、萃取温度、浸泡液pH、浸泡(贴合)温度、浸泡(贴合)时间为主要影响因素,设计正交试验,探讨纺织品中可迁移性荧光增白剂的迁移规律。纯棉内衣面料中可迁移性荧光增白剂在水中的迁移量明显高于模拟人体体液中。浸泡法中影响迁移量的主要因素是萃取温度、萃取液、浸泡时间,贴合法中影响迁移量的主要因素是萃取液、贴合时间、贴合温度;填充物聚酯纤维中不含可迁移性荧光增白剂,在各种试验条件下均未发生迁移。The qualitative test methods of migratory fluorescent whitening agents in textile products for infants and children are explored,and the migration patterns and influencing factors are studied.Two test methods of immersion and lamination are designed by simulating sweating,drooling and bathing during the wearing of in-fant underwear.The orthogonal experiments with the main influencing factors of extraction solution,extraction time,extraction temperature,pH of immersion solution,immersion(lamination)temperature and immersion(lamination)time are designed,and the migration patterns of migratory fluorescent whitening agents in textiles are explored.The migration amount of migratory fluorescent whitening agents in cotton underwear in water is significantly higher than that in simulated human body fluids.The main factors affecting migration in the immer-sion method are extraction temperature,extraction solution and immersion time,while the main factors affect-ing migration in the lamination method are extraction solution,sticking time and sticking temperature.The filler polyester fiber does not contain migratory fluorescent whitening agents and has not undergone migration un-der various experimental conditions.
