摘　　要：以二甲胺、环氧氯丙烷、四乙烯五胺为主要原料,制备了一种无甲醛多胺型固色剂.通过实验,确定了合成多胺型固色剂的最佳合成工艺及最佳固色工艺.最佳合成工艺为：将摩尔比为1∶1.5的二甲胺、环氧氯丙烷于28℃左右反应2h后,加入占单体总量2%的四乙烯五胺,在70℃反应5h.最佳固色工艺为：染色棉织物→两浸两轧（整理剂40g/L,轧余率80%）→烘干（100℃）.整理织物后,可使直接染料的各项牢度提高1~2级,且对色光影响较小.One kind of non-formaldehyde polyamine fixing agents is synthesized with dimethylamine,epichlorohydrin and tetraethylene pentamine.According to experiments,the best synthesis process and the best fixing condition is decided.The best synthesis process is： dimethylamine and epichlorohydrin whose molar ratio was 1∶1.5 react at about 28℃ for 2h,then add tetraethylene pentamine which account for 2% of the total monomers,react at 70℃ for 5h.The best fixing condition of dyed cotton fabric is：two dip two rolling（dosage of the finishing agent is 50g/L,rolling over rate is 80%） and then dry at 100℃.After the treatment,various fastness of direct dyes raise about 0.5～2 grade and the color change is small.
