| 摘 要： | Cationic modifying agent (PECH-amine) with lower molecular weight and containing less nitrogen was prepared and characterized. The water-soluble cationic modification agent has high reactivity for cotton. Cotton modified by this agent can be dyed under salt-free and neutral conditions with direct and reactive dyes. Dyes in the dyebath could be completely exhausted and a dyeing effluent without residual dyes and salt could be expected.
