摘要
为了降低无机盐在活性染料染色过程中对环境的影响,将聚丙烯酸盐和聚马来酸盐代替Na2SO4作促染剂,用于纯棉织物活性染料轧染。通过测试比较染色织物的表观色深(K/S值)、各项牢度和强力指标,探讨了聚羧酸盐作为代盐剂在纯棉织物活性染料轧染工艺中应用的可行性,并就聚羧酸盐在轧染工艺中的促染机制进行了初步探讨。结果表明,当聚羧酸盐用量为50 g/L时,纯棉染色织物的K/S值、各项牢度指标和织物强力均与Na2SO4作促染剂时相当,基本能够满足染色要求。
The paper was aimed at investigating the possibility of using polyacrylate and polymaleate in the pad dyeing of cotton fabrics with reactive dyes in place of Na2 SO4 as dyeing promoter. For this purpose, K/S values, color fastness and strength of the dyed cotton samples were measured and contrasted. The feasibility and dyeing promotion mechanism of polycarboxylates in the pad dyeing were also discussed. The results showed that when dosage of polycarboxylate is 50 g/L, the K/S value, fastness properties and strength of the dyed fabric are comparable to those with Na2SO4 as dyeing promoter.
