摘　　要：制备了一种环保型释酸剂Degbuf?A35,用于锦纶织物弱酸性染料染色,测试了释酸剂的耐硬水性、耐水解性、pH值滑移范围、缓染性能等。研究表明,释酸剂Degbuf?A35具有良好的耐硬水、耐水解性能,pH值滑移范围较宽。相对于醋酸,释酸剂Degbuf?A35的初始pH值更高,染料的初染率更低;相对于硫酸铵,释酸剂Degbuf?A35最终的得色量更高。拼色染色试验表明,释酸剂Degbuf?A35用于锦纶织物弱酸性染料染色,匀染性好、得色量高,与市售释酸剂应用性能相近。An environmental-friendly acid-releaser Degbuf?A35 is prepared and applied to nylon dyeing with acid dyes.The properties of hard water and hydrolysis resistance,pH sliding range and retarding performance are investigated.Degbuf?A35 has good resistance to hard water and hydrolysis,and a wide sliding range of pH values.Compared with acetic acid,Degbuf?A35 exhibits a higher initial pH,resulting a lower initial exhaustion rate.Compared with(NH4)2SO4,Degbuf?A35 has a higher color yield.The combination dyeing of acid dyes shows that the dyed fabric assisted with Degbuf?A35 has desir able color levelness and yield,which is comparable to that of commercial acid-releaser.
