摘　　要：采用自制的双活性新型阳离子改性剂,分别以浸轧冷堆法和浸渍法对棉织物进行改性,再进行活性染料染色。研究了改性棉的染深性、匀染性及碱剂用量对染色牢度的影响,并与市售单活性改性剂进行对比。结果表明,采用浸轧冷堆法,双活性改性剂与单活性改性剂处理后的棉织物具有相似的染深性和较高的染色牢度;采用浸渍法,双活性改性剂处理棉的染色性能比单活性改性剂处理棉有显著提高。Cotton fabric IS mOdltlea Witn a self-synmeslzea DI-functional cationic by cold pad-batch process and exhaust processes respectively, and then is dyed with reactive dyes, Dye adsorption, dyeing levelness and the effects of alkali concentration on color fastness of cotton dyeings are dis- cussed, The results show that compared with commercial mono-reactive cationic modifier, the cotton dyeings treated with bi-functional cationic modifier have similar dyeuptake and higher fastness when us- ing cold pad-batch process and improved color yield and color fastness when using exhaust process.
