摘　　要：选用大爱尼克斯分散染料对PET/PA超细纤维无纺布进行轧染,研究了海藻酸钠、扩散促进剂PB用量及焙烘条件等因素对K/S值和匀染性的影响。优化的涤锦超细纤维无纺布分散染料轧染工艺为:扩散促进剂PB5g/L,海藻酸钠5g/L,焙烘条件170℃×2min。采用该工艺染色的涤锦超细纤维无纺布各项色牢度良好,均可达3级以上。Pad dyeing was carried out on superfine PET/PA non-woven fabric with Dianix disperse dye. Influences of dosage of alginate sodium, diffusion accelerator PB and curing condition on K/S value and evenness were discussed. The optimum pad dyeing process was determined as follows： dyeing with alginate sodium 5 g/L, diffusion accelerator PB 5 g/L and curing at 170 ℃ for 2 minutes. The dyeings featured good color fastness with all above grade 3.
