采用反应型阻燃剂2,3 -二溴丁二酸酐（DBSA）对涤纶/棉混纺织物进行衬垫-干固化，使其具有持久阻燃性能。以马来酸酐和溴为原料，在乙酸乙酯溶液中加成合成DBSA，通过溶剂析出结晶法提取DBSA。以次亚磷酸钠为催化剂，先用DBSA对棉织物进行整理。测定了与棉花酯化的DBSA的热行为和用量。采用焦伏乐CP new作为对照。从热重分析结果推测，纤维素与DBSA的酯化反应在热分解初期类似于磷酸酯。DBSA还应用于涤纶和涤纶/棉混纺织物。对织物的阻燃性、热性能和耐久性进行了研究。在PET和PET/棉上也观察到DBSA的凝聚相效应。
For a poly(ethylene terephthalate) (PET)/cotton blended fabric, a reactive-type flame retardant 2, 3-dibromo-succinic anhydride (DBSA) was used to endow durable flame retardancy via the pad-dry-cure method. DBSA was synthesized via the addition reaction of maleic anhydride and bromine in ethyl acetate solution and extracted by solventing-out crystallization. DBSA was used to finish a cotton fabric firstly with sodium hypophosphite as the catalyst. Thermal behaviors and amount of DBSA that esterified with the cotton was determined. Pyrovatex CP new was applied as a comparison. It was speculated from the thermogravimetric analysis result that esterification of cellulose with DBSA worked similar to phosphate-ester at the initial stage of thermal decomposition. DBSA was also applied to PET and PET/cotton blended fabrics. Flame retardancy, thermal behaviors and durability of the finished fabrics were investigated. Evidence of the condensed phase effect of DBSA was also observed on PET and PET/cotton.
