【摘要】 选用Dorolan黑色染料应用于非织造仿皮革布深色染色加工,采用多次吸尽染色法与追加染料连缸染色法,考察染色后残余染液的再利用价值,分析其对非织造仿皮革布浓深色染色残液之再利用的可行性。研究表明,Dorolan Black RB和Dorolan Black MRX染料都有较高的上染吸附率和着色强度,均适合仿皮布的深色染色。通过吸尽染色法,可以提高染料的利用率,Dorolan黑色染料染色仿皮革布的最终上染率均能达95%以上,对仿皮染色样的色牢度和色调影响也很小。通过追加染料连缸染色加工法,所染仿皮革布缸次间染色样的表观颜色深度、色调一致性较好。残液的再利用可降低染料成本和减少废液排放。更多还原

【Abstract】 Dorolan black dye is applied into dark dyeing of non-woven imitation leather cloth.This paper investigates the reuse value of residual dyeing liquid after dyeing and analyzes the feasibility of reusing dark residual dyeing liquid of non-woven imitation leather cloth with multiple absorption dyeing method and the method of dyeing in successive vat with additional dye.The research shows that Dorolan Black RB and Dorolan Black MRX dyes both have a high dye absorption rate and dye color intensity and apply to dark dyeing of imitation leather cloth.With absorption dyeing method,the utilization rate of of dye can be improved;the final dye-uptake of imitation leather cloth dyed by Dorolan black dye can reach over 95% and it has a small influence on the color fastness and color tone of imitation leather dyeing sample.With the method of dyeing in successive vat with additional dye,the dyeing sample of imitation leather cloth dyed has a good apparent color depth and color tone consistency.The reuse of residual liquid can reduce the cost of dye and emission of exhausted liquid.更多还原
