活性染料低温皂洗工艺

Low temperature soaping in reactive dyeing

应用低温皂洗剂LS与生物酶拼混,对纯棉纱线活性染料染色后进行低温皂洗,讨论了温度、时间、助剂用量等对皂洗后纱线牢度性能及皂洗残液色度的影响,得出了最佳低温皂洗工艺:皂洗剂LS1～3g/L,助洗酶0.1～0.3g/L,80℃皂洗15min。

Combined low-temperature soaping agent LS with enzyme, soaping after reactive dyeing of cotton yarn at low tem- perature was carried out. The influences of temperature, time and dosage of additives on fastness properties after soaping and color of soaping residue were discussed. The optimum process was obtained： soaping agent 1 ~ 3 g/L, washing enzyme 0. 1 ~ 0.3 g/L, soaping at 80 ℃ for 15 min.
