摘要
用于皮革和纺织品染色的部分偶氮染料可还原出对人体有致癌性的芳香胺。GB 28007-2011《儿童家具通用技术条件》等标准对纺织面料和皮革用偶氮染料中的致癌芳香胺均作出了严格限制。阐述了偶氮染料的起源、着色机理、致癌机理及其应对措施。在致癌机理方面,目前大多数专家认为主要通过偶氮染料在动物体内发生还原开裂生成芳香胺,芳香胺继而在人体中代谢为芳氮烯阳离子实现的。
The azo dyes for leather and textile dyeing can release the aromatic amines which is cancerogenous to human body. The GB 28007-2011 ＂General technical requirements for children＇s furniture＂ and other standards have made strictly limit on carcinogenic aromatic amines in azo dyes used for textile fabrics and leathers. This article explains the origin of azo dyes, coloring mechanism, carcinogenic mechanism and response measures. Most experts believe that carcinogenic mechanism of azo dyes is first producing aromatic amines through reductive cleavage reaction of azo dyes in animals, and then forming arylnitrenium ions in the human metabolism process.
