| 中文摘要: |
| 合成了吡唑啉酮单偶氮黄色和1,4-二氨基蒽醌系蓝色四乙烯五胺型交联染料，利用分子链上剩余氨基的高反应性及同一分子链上存在多个可反应基团的优点，通过交联染色和固色实现染料在纤维上的超高固色率，实现染色的绿色化．用浸染和轧染的染色方法将交联染料应用于丝绸和棉纤维染色，然后用硫酸酯乙基砜型交联剂，两浸两轧、焙烘固色染色纤维．研究结果表明在pH为4时该两只染料竭染率最高，并且用交联剂固色后交联率均大于98%，染色纤维具有较好的日晒牢度、摩擦色牢度和水洗色牢度． |
| 英文摘要: |
| Two tetraethylene pentamine type crosslinking dyes, pyrazolone mono azo yellow and 1,4-diaminoanthraquinone blue were synthesized. As the dyes contain high reactivity of residual amino and a certain number of reactive groups, a super-high dye fixation on fibre is expected to be achieved through crosslinking dyeing and fixation which realizes the green dyeing. The silk and cotton dyed with the polyamine dyes were fixed via crosslinking agent (sulphatoethylsulphone type), which acted as a bridge between the fibre and the dye molecule through two times of dipping and rolling as well as baking. The results show that the best pH for dyeing is 4, and the overall fixation efficiency of the crosslinking dye of high affinity is more than 98%. The dyed samples exhibit good fastness to light, washing and rubbing. |
