摘　　要：在羊毛／锦纶／腈纶多种纤维的同浴染色中，选用弱酸性染料染羊毛和锦纶，阳离子染料染腈纶，同时在染浴中加入适量的沉淀防止剂和锦纶阻染剂，以提高染料在染浴中的稳定性。染浴的pH值一般控制在4—5，始染温度为40℃，升温至98℃保温染色，此工艺可确保三种纤维具有优异的同色性。In one bath dyeing process of wool/nylon/acrylic fibers, appropriate dyestuffs are screened, which is, weak acid dyes for wool and nylon, and cationic dyes for acrylic fiber. Some anti precipitation agent and dye retardant for nylon are added to dye liquor. Union dyed fibers are available if controlling pH value at 4 -5, raising dyeing temperature from 40℃ to 98℃.
