| 摘 要： | 为解决涤纶/棉混纺织物水浴染色能耗大、水污染严重的技术难题,并拓宽超临界CO2染色技术的应用范围,研究了活性分散黄染料对涤纶/棉混纺织物在超临界CO2流体中的染色性能。分析了染色温度、压力、时间、助剂用量和CO2流速对涤纶/棉混纺织物染色效果的影响,得到最佳染色工艺条件:染色温度为100 ℃,压力为20 MPa,染色时间为80 min,CO2流量为20 g/min,二甲基亚砜质量分数为80%。结果表明:与天然染料相比,利用活性分散黄可以显著提升涤纶/棉混纺织物的染色深度和色牢度;同时,二甲基亚砜处理与“乙醇助溶剂+N-甲基吡咯烷酮(NMP)预处理”法相比,K/S值提升了2倍以上,色牢度达到4~5级,获得了较好的染色效果。

| Abstract: | In order to solve the technical problems of energy consumption and serious water pollution in polyester/cotton blended fabric water dyeing, dyeing properties of polyester/cotton blended fabrics in the supercritical CO2 was investigated by using Reactive Disperse Yellow dye in order to expand the application range of supercritical CO2 dyeing technology. The effect of dyeing temperature, pressure, time, dosage of co-solvent and CO2 flow rate on the dyeing properties of polyester/cotton blended fabrics was analyzed. The optimized process condition was obtained to be dyeing temperature 100 ℃, pressure 20 MPa, dyeing time 80 min, CO2 flow 20 g/min and dimethyl sulfoxide (DMSO) dosage 80%. Reactive Disperse Yellow dye could significantly improve color depth and color fastness of polyester/cotton fabrics in comparison with natural dyes. Compared with "ethanol+N-methylpyrrolidone(NMP)" pretreatment, the K/S value of DMSO treatment was increased by more than two times, and the color fastness reached grade 4-5, presenting excellent dyeing effect. |
