自德国政府和欧共体颁布22种致癌中间体和相应的118种禁用染料以来,各国都在致力于开发禁用染料的代用产品,特别是黑色和棕色直接染料,我国也非常重视这项工作,并把它列为“九五”国家重点科技攻关项目之一,而由我国最早生产直接染料的企业之一——上海三泰染料化工厂来承担,题目名为“直接黑D-ANBA和直接棕NBR中试技术研究”.经过该厂工程技术人员近两年的攻关,最近终于结出丰硕的成果,并于1998年底在国家石油和化学工业局主持下通过了技术鉴定.
Since the German government and the European Community promulgated 22 kinds of carcinogenic intermediates and 118 kinds of banned dyes, all countries are working to develop alternative products that use banned dyes, especially black and brown direct dyes. Our country also attaches great importance to this work. And it was listed as one of the “Ninth Five-Year” national key scientific and technological projects, and it was undertaken by Shanghai Santai Dye Chemical Factory, one of the earliest enterprises producing direct dyes in China. The title was “Direct Black D-ANBA and Direct “Brown NBR pilot test technology”. After the plant engineering and technical personnel in the past two years of research, has finally yielded fruitful results, and passed the technical appraisal under the auspices of the National Petroleum and Chemical Industry Bureau at the end of 1998.
