摘　　要：采用中性固色活性染料分别对木棉/棉混纺织物(20/80)和棉织物进行染色。研究了氯化钠、pH调节剂和染料用量,以及染色温度和时间等对木棉/棉混纺织物染色性能的影响,并与棉织物进行对比,测试了染色织物的K/S值和染色牢度。结果表明,中性固色活性染料染色木棉/棉混纺织物的最佳工艺为染料2%(omf),NaCl 50 g/L,pH调节剂1 g/L,100℃染色60 min。染色织物具有较高的表观色深,染色牢度能够达到服用要求。The dyeing of kapok/cotton blended fabrics and cotton fabrics with reactive dyes fixed at neu- tral conditions are carried out. The effects of the dosage of sodium chloride, pH conditioner and reactive dyes, dyeing temperature and time on dyeing performance of the kapok/cotton blends are analyzed. The K/S value and color fastness of the dyed fabrics are also determined. The results show that the opti- mal dyeing process is dye 2% （omf）, sodium chloride 50 g/L, pH conditioner 1 g/L, dyeing at 100 ℃ for 60 min. The K/S value of the dyed fabric is higher, and the color fastness can meet the requirements of wearability.
