Remazol/ disperse dyes were used to dye T/ R fabrics instead of vat/ disperse dyes on overflow jet dyeing machine. 喷射溢流染色法染涤粘织物时,用雷马素活性染料/分散染料代替士林染料/分散染料。
SBR reactor was used as the biochemical treatment equipment in studying the result of degradation of the organics in the wastewater from printing and dyeing industry that contained reactive dye, direct dye and vat dye and was treated by SBR method and internal electrolysis-SBR method. 以SBR反应器作为生化处理装置,考察了用SBR法和内电解-SBR法处理含活性染料、直接染料及还原染料的印染废水的有机物降解效果。
During the finishing process of cellulose enzyme to ramie fabric, it can be seen that the reactive dye can restrain the cellulose enzyme, and vat dye ( not ion type) basically has no effect to cellulose enzyme. 在纤维素酶对苎麻织物整理的过程中,反应型活性染料抑制纤维素酶的作用,非离子型还原染料对酶基本无影响。
Leuco vat dye molecules rarely exist in the single-molecule forms, mostly in the dozens of molecular aggregates, or in the form of hundreds of moleculars, indicating that Leuco vat dye solution is not a true solution, but mainly in the range of colloid. 染料隐色体分子很少以单分子状态存在,大都以几十个分子的聚集体或缔合体形式存在,表明还原染料隐色体溶液不是真溶液,而主要是位于胶体范围分布。
Vat dye is mainly used to dye cellulose fibers. At home and abroad, Vat dyes are for increasing demand with the development of social economy. 还原染料主要用于纤维素纤维的染色,目前国内外对还原染料的需求量随着社会经济的发展而越来越大。
Dispersants play a crucial role in the dye commercialization and application of disperse and vat dye. 分散剂在分散、还原染料商品化加工和应用过程中起着至关重要的作用。
