摘　　要：用还原蓝BC染PTT纤维织物,探讨了染浴的pH值、染色温度、时间、尿素的用量对染色深度的影响。结果表明,在pH值为6,110℃下染60min可得到很好的染色效果,尿素的加入可以提高得色深度。各个浓度下,还原蓝BC对PTT纤维织物染色后都具有很好的摩擦色牢度、皂洗色牢度。Vat Blue BC is used to dye PTT fabric, and effects of pH value of dye bath, dyeing temperature and time, amount of added urea on dyeing depth are discussed. Results show that PTT fabric dyed at 110℃, pH value 6 for 60 minutes reaches ideal dyeing effect. Dyeing depth is increased by adding urea. The PPT fabric dyed with Vat Blue BC at different bath concentrations show good colour fastness to rubbing and soaping.
