摘要
采用丽华实活性染料对亚麻织物进行冷轧堆染色,并对染色工艺进行探讨。在对染料固色率的影响因素(碱剂用量、堆置时间、堆置温度、促染剂用量、轧余率)进行单一分析的基础上,应用正交试验确定了亚麻织物活性染料冷轧堆染色的优化工艺,即染料用量5 g/L、尿素60 g/L、纯碱20 g/L、烧碱10 mL/L、NaC l40 g/L、轧余率80%,堆置温度25℃,时间4.5 h。
Cold pad-batch dyeing process of linen fabric with Levafix reactive dyes is carried out, influences of alkali dosage, batching time and temperature, addition of promoter, and pick up are analyzed, the optimum conditions are defined via orthogonal experiments, that is, dye concentration 5 g/L, urea 60 g/L, soda ash 20g/L, caustic soda 10mL/L, NaCl 40g/L, pick up 80%, batching at 25℃ for 45 hours.
