聚对苯二甲酸乙二醇酯纤维的染色改性

Dyeing modification of polyethylene terephthalate fiber

聚对苯二甲酸乙二醇酯(PET)纤维通常需要在高温高压条件下用分散染料染色,浪费能量,增加碳排放量。重点介绍了分散染料常压可染聚酯和3种阳离子染料可染聚酯(CDP、ECDP和NECDP)的化学结构设计思路。

Polyethylene terephthalate(PET)fibers often need to be dyed with dispersed dyes at high temperatures and pressures,which waste energy and increase carbon emissions.The chemical structure design ideas of atmospheric pressure dyeable polyester with disperse dyes and dyeable polyester with three cationic dyes(CDP,ECDP and NECDP)are introduced.
