摘要：A series of blue crosslinking dyes EDCD, DTCD, TPCD, PVAmCD and PAAmCD were synthesized by the reaction of 1,4-dihydroxyanthraquinone with ethylenediamine, diethylenetriamine, tetraethylethylenediamine, polyvinylamine and polyallyl amine. These crosslinking dyes can be classified into two kinds, i.e. small crosslinking dyes and polymeric crosslinking dyes. These dyes were crosslinked to cotton via covalent bond by a new crosslinker NSC prepared from 4,5-diamino-2,7-naphthalenedisulphonate and cyanuric chloride. The effects of crosslinking dyeing conditions, such as NSC concentration, curing temperature and pH of crosslinking bath on the dye fixation were investigated in detail. At optimum conditions, the fixations of EDCD, DTCD, TPCD, PVAmCD and PAAmCD using NSC as a crosslinker on cotton were 91.2%, 95.6%, 99.1%, 99.4% and 99.2%, respectively. The wrinkle recovery of crosslinking dyeing was also studied. These results indicated that the polymeric crosslinking dyes showed better performance than the small ones.
