摘　　要：含氟拒水拒油整理涤纶染色布修色时,需先剥除拒水拒油整理剂。试验采用氟树脂去除剂DEF,以浸渍法剥除织物上的整理剂。根据水洗前后织物的拒水拒油性能,讨论了去除剂用量、烧碱用量、温度、时间对剥除效果的影响,优化的剥除工艺为:去除剂DEF 1.0~1.5 g/L,烧碱1 g/L,浴比1∶20,温度90~100℃,时间20 m in。结果表明,去除剂DEF可有效地剥除含氟整理剂,重新整理后织物拒水等级达到100分,拒油级别达到5级,对色光影响较小,强力稍有下降。The fluorochemical water-and oil-repellent on textiles must be stripped firstly in color restoration of finished polyester dyeings.The stripping process is carried out by immersion method with fluorocarbon remover DEF.Influences of remover dosage,NaOH dosage,stripping temperature and time on the stripping effects are investigated according to the water-and oil-repellent effect of polyester fabric before and after washing.The optimum stripping process is as follows: fluorocarbon remover DEF 1.0~1.5 g/L,NaOH 1 g/L,material ratio 1 ∶ 20,stripping at 90~100 ℃ for 20 min.The results show that fluorocarbon remover DEF features good stripping effect.The water repellent effect of refinished fabric reaches 100 and the oil-repellent effect is 5.The refinished fabric has a little change in K/S value and a little decrease in tear strength.
