摘要(Abstract):
从纺织的源头——聚酯化学改性着手,实现改性迭代涤纶的低温常压沸染,能够解决印染行业的节能与减排问题。如按2 000万t/a涤纶采用常压染色技术计算,可减少碳排放约60亿t/a。新型阳离子染料常压可深染迭代涤纶,可在深染的同时,上染率达99%以上,清澈的染后残液还可多次循环再利用,且K/S值高、色差ΔE小、色牢度高。
Starting from the source of textiles—polyester chemical modification, the low-temperature and atmospheric boiling dyeing of modified iterative polyester is realized, which can solve the problems of energy conservation and emission reduction in the printing and dyeing industry. If 20 million tons/year polyester is used for low-temperature and atmospheric dyeing technology, carbon emissions can be reduced by about 6 billion tons/year. The new cationic dye dyeable iterative polyester can deep dye under normal pressure, and at the same time, the dyeing rate is over 99%, the residual liquid after dyeing is clear, and can be recycled many times, the K/S value is high, the colour difference ΔE is small, dyeing fastness is very good.
