摘　　要：在羊毛织物酸性媒介染料染色工艺中,通过加入媒染促进剂以提高重铬酸钾的利用率,降低其用量,并在染色后加入除铬皂洗剂进行皂洗,降低织物上的的游离铬离子浓度。优化的羊毛酸性媒介染料染色工艺为:醋酸4%(omf),甲酸2%(omf),重铬酸钾1.2%(omf),媒染促进剂2%(omf)。该染色工艺色牢度较高,得色深,羊毛染色受损较少,纱线强力提高,铬污染较低,环保性好。In mordant acid dyeing of wool, promoting agent is used to enhance the utilization of potassium dichromate and de- crease its dosage, and soaping is carried out with chrome remover to reduce the free chromium ion concentration of the fabric afterward. The optimum mordant acid dyeing process is： acetic acid 4%（omf）, formic acid 2%（omf）, potassium dichromate 1.2% （omf） and promoting agent 2% （omf）. The optimum dyeing process features good color fastness, high color yield, re- duced wool damage, improved yarn strength, low chromium pollution and environmental-friendly.
