摘　　要：阳离子涤纶混纺织物在高端服装领域具有广泛的应用潜力,但其染色过程中存在染料利用率低、水耗高的问题,限制了其进一步的推广应用。为探究阳离子涤纶混纺织物在硅基非水介质中的染色工艺条件,利用单因素实验及响应面法对染料用量、十甲基环五硅氧烷(D5)用量、染色时间等影响织物色深(K/S值)的工艺进行优化,并对染色织物的色牢度进行评价。结果表明:在硅基非水介质中,当染色温度108℃、染料用量1.6%(o.w.f)、D5用量93.5%(o.w.f)、染色时间60 min及pH为4~5时,染色织物的K/S值达最高,且明显高于传统水浴染色;该染色过程节水93.5%,染色织物色牢度在4-5级以上。研究结果可为阳离子涤纶混纺织物的清洁染色提供有益参考。The polyester fiber is the largest variety of synthetic fibers in the world,which occupies a very important position in the field of textile and garment.With the improvement of people's living standards,people have also put forward new requirements for polyester blended fabrics,paying more attention to their comfort and functionality.Compared with ordinary polyester,cationic(dyeable)polyester has a softer texture than ordinary polyester,and has a certain hydrophilicity and unique two-color effect.However,in the dyeing process,the energy consumption and water consumption are high,and the production efficiency is low.The wastewater is not conducive to direct discharge,and the wastewater has high color,unstable pH,organic pollutants and high content of refractory components,resulting in a large number of wastewater and wastewater recovery.In addition,the use of various additives increases the difficulty of subsequent fabric cleaning,and the dyeing process is cumbersome and not environmentally friendly,which limits its further industrial development.To explore the dyeing process of cationic polyester blended fabrics,the response surface method(RSM)was used to optimize the process of cationic dyeable polyester,with decamethylcyclopentasiloxane(D5)as the medium and K/S value as the corresponding value.The main factors affecting the dyeing process of cationic dyeable polyester were screened by Plackett-Berman experiment through the influence of single factors on the dyeing process,such as dye dosage,D5 dosage and dyeing time.P value less than 0.05 was considered to have a significant impact on this factor,and P value less than 0.01 was considered to have an extremely significant impact on this factor.According to the P value,it was found that the dyeing temperature was the biggest factor affecting the K/S value,followed by the amount of dye and the amount of D5.On this basis,three factors having a significant effect on the color depth value were selected,and the response surface method(RSM)was established by using the c
