The passage introduces a high-concentrated organic fixing agent HC~ which was applicable to all kinds of reactive dyes, including Dyeing at Low Liquor Ratio. Perfect tinctorial yield and reproducibility were achieved when used on different structured reactive dyes. It was act as fixing agent when dyeing in the reactive dyes. It consumes only 1/8~1/10 compared with Sodium carbonate and shortened 20-30 minutes with excellent leveling effect and low dyeing disadvantages. Furthermore, owing to the less consumption, the textile is easier to wash, cutting down the washing times, eliminating acid wash and saving great: amount on energy as well as working hours. It only consumes half of the water compared with Sodium carbonate techniques and 1/3 of gas consumption. This can greatly reduce amount of waste water and alkali content. Different from the Substitution alkali which was sold in the market, it is a high concentrated and organic liquid. In its molecular structure, the carbon chain of hydrophobic groups is shorter, water-soluble groups and hydrophilic group are included, which plays important role in the buffer solution system regarding fluxing, penetrating, dispersing, retarding and migrating.%该文介绍了一种自主研发的高浓液体有机固着剂HG，它适用于各种类型的活性染料的染色，也适用于小浴比染色新工艺。对各种结构的活性染料能得到较高的给色量和良好的重现性。它在活性染料染色时用作固色剂，其用量仅为纯碱的1／8～1／10，加碱时间缩短为20～30min，匀染效果佳，可大幅降低染色疵病率。同时，由于用量少，染色后的织物易于洗涤，可以减少水洗道数，省去酸洗，节约了大量的水和汽及工时，用水量仅为纯碱工艺的1／2，蒸汽用量仅是纯碱工艺的1／3，减少了污水和污水中碱剂含量。它和已进入市场的代碱剂有所不同，它是高浓液体的、有机的，它的分子结构中疏抽№基团碳链较短，含有一定的水溶性基团和亲水基团，在缓冲溶液体系中起着助溶、渗透、分散和缓染及移染作用。
