摘　　要：研究证明经聚环氧氯丙烷胺化物(PECH-amine)改性后的废弃纤维素纤维可有效用于阴离子染料废液的脱色或前处理。探讨了改性剂浓度、改性织物的形状及类型对阴离子染料废液脱色率的影响,并计算出改性纤維在模拟阴离子染料废液中可脱染料的量。Cellulosic fibres treated with agents polyepichlorohyrin-dimethylamine (PECH-amine) can be used in the decoloration or pretreatment of dyeing effluent caused by anionic dyestuffs. It is an economic and reliable process. The effects of agent concentrations, shapes and types of treated fabers are also discussed.
