摘　　要：为探究自制的乙烯基磷氮类阻燃剂(PN)接枝蚕丝织物的阻燃效果,研究了工艺因素对蚕丝织物接枝率的影响及接枝率与阻燃效果的关系,对整理后蚕丝织物的阻燃耐久性、燃烧后的炭渣形态、磷氮元素含量及织物的物理性能、染色性能进行观察测试。结果表明:经PN接枝处理后的蚕丝织物表现出较好的阻燃效果,且不影响织物本身的物理性能,接枝率越高,极限氧指数(LOI值)就越大;当PN的接枝率达到15.4%时,蚕丝织物的LOI值可以达到31.2%,经过50次的水洗处理后,其LOI值仍能达到30.9%。For the purpose of exploring flame retardant effect of silk fabric grafted by the home-made vinyl phosphorus nitrogen flame retardant（PN） , effects of process factors on silk fabric＇s grafting rate and relationship between grafting rate and flame retardant were investigated. Then the washing fastness, morphology of combustion carbon residue, element content of phosphorus-nitrogen and physical and dyeing performance of finished silk fabrics were observed and measured. The results showed that property of silk fabric＇s flame retardant grafted by PN was good and the limit oxygen index（LOI） increased with the grafting rate＇s growth. The LOI achieved 31.2% with the grafting rate of 15.4% under this condition. The LOI was still 30.9% after washing for 50 times.
