摘　　要：通过测定不同碱剂溶液的碱性,以筛选和配制活性染料染色代用碱,并应用于纯棉织物活性染料轧蒸法染色。优化的代用碱剂组分为碳酸钾35%、五水偏硅酸钠50%、氢氧化钾8%和三乙醇胺7%。以配制的代碱剂为活性染料染色的固色碱剂,其用量仅为纯碱的1/10～1/7,染色织物得色量较高、固色效果较好、色光稳定,色牢度良好,且可以减少水洗次数。By measuring the alkalinity of different alkali solutions, alternative alkali is selected and prepared, and is applied to reactive dyeing of cotton fabric by pad-steam method. The optimized components of alternative alkali are potassium carbonate 35%, sodium metasilicate 50%, caustic potash 8% and triethanolamine ？%. The dosage of prepared alternative alkali is 1/7 - 1/10 of soda in fixation of reactive dyeing. The washing times are reduced. The dyeings feature higher color yield, stable shade, better fixation and color fastness.
