摘　　要：合成一种用于促进天然染料上染棉纤维的染色促进剂MA-1,可大幅提高天然染料上染率和耐水洗色牢度。研究了阳离子单体、环状结构单体含量以及相对分子质量对其性能的影响。棉纤维经MA-1预处理后,桑葚和紫娇天然染料上染率提高3倍以上,耐水洗色牢度提高2〜3级。A dyeing promoter MA-1 is synthesized to promote the dyeing of cotton fiber with natural dyes.The dye uptake and color fastness to washing of natural dyes are greatly improved.The effects of the content of cationic monomer,cyclic monomer and relative molecular mass on its properties are studied.After pretreated with MA-1,the dye uptake of mulberry or tulbaghia violacea natural dyes is increased by more than 3 times.and the color fastness to washing is improved by Grade 2~3.
