摘　　要：以四乙烯五胺为原料，合成了1，4-二氨基葸醌系蓝色四乙烯五胺型交联染料，并将其应用于丝绸和棉纤维染色，然后用2，4-二氯-6-（氨基苯-4’-磺酸酯乙基砜）均三嗪交联剂（DAST），采用两浸两轧、焙烘工艺对染色纤维固色效应进行了研究．结果表明，在pH为7、交联剂质量浓度为20g／L时，该交联染料的最终固色率为99％，染色纤维耐洗、耐日晒及耐摩擦色牢度分别达为4-5级、4级和3—4级以上，与小分子活性染料相当，并具有一定防皱整理效果．The blue polyamine crosslinking dye was synthesized via the reaction of tetraethylenepentamine with leuco 1,4 - dihydroxyanthraquinone. The silk and cotton dyed with the polyamine dye were fixed via crosslinking agent （2 - chloro - 4,6 - di （ aminobenzene - 4＇ - β - sulphatoethylsulphone） - 1,3,5 - s - triazine）, which acted as a bridge between the fibre and the dye molecule. The results showed when the best pH value for crosslinking was 7, and mass concentration of crosslinking agent was 20 g/L, the overall fixation efficiency of the crosslinking dye of high affinity was at 99%. The washfastness, lighffastness and rubfastness of polyamine crosslinking dye were more than 4 - 5 grade, 4 grade and 3 - 4 grade respectively.
