摘要：为了满足对蚕丝织物生态阻燃的需求，以 1-(3-二甲氨基丙基)-3-乙基碳二亚胺盐酸盐（EDC）和 N-
羟基琥珀酰亚胺（NHS）为催化剂将磷酸腺苷（AMP）引入蚕丝织物制得改性丝织物。采用 FTIR、SEM、
EDS 对改性前后丝织物的化学结构、表面形貌和元素含量进行表征，采用极限氧指数仪、织物阻燃性能测
试仪、锥形量热仪和热重分析仪对其阻燃性能和热稳定性进行测试，同时对改性前后丝织物的拉伸断裂强
力、透气性和织物风格进行了测试。结果表明，改性丝织物表面呈现颗粒状覆盖物，且均匀分布着磷元素。
改性丝织物增重率达 13.31%时，极限氧指数达 30.10%，与原丝织物相比，其失重率降低 13.06%，热释放
速率降低了 30.6%，损毁长度减少了 11.1 cm，并出现明显炭层。经 50 次洗涤后，改性丝织物极限氧指数
仍能达到 25%以上，说明改性丝织物具有较好的耐洗性能。

Abstract: In order to meet the demand for ecological flame retardancy of silk fabric, adenosine phosphate
(AMP) was introduced into silk fabric with 1-(3-dimethylaminopropyl)-3-ethyl carbodiimide hydrochloride
(EDC) and N-hydroxysuccinimide (NHS) as catalysts. The chemical structure, surface morphology and
element content of silk fabric before and after modification were characterized by FTIR, SEM and EDS.
The flame retardancy and thermal stability were tested by limit oxygen index tester, fabric flame retardant
performance tester, cone calorimeter and thermogravimetric analyzer. The tensile breaking force, air
permeability and fabric style of silk fabric before and after modification were tested. The results showed
that there were obvious particle- like coverings on the surface of modified silk fabric, and phosphorus
elements were evenly distributed. The weight gain rate of modified silk fabric reached 13.31%, the limit
oxygen index reached 30.10%. Compared with those of original silk fabric, the weight loss, heat release rate
and damage length of the modified silk fabric were decreased by 13.06%, 30.6% and 11.1 cm, respectively.
After 50 times of washing, the limit oxygen index of modified silk fabric still was over 25%, indicating that
the modified silk fabric had better washing resistance.
