摘　　要：分别合成了单季铵盐基和双季铵盐基阳离子改性剂,讨论了阳离子改性剂种类和质量分数,氢氧化钠质量浓度,改性温度和时间,以及染液pH值对活性超级红RW200%染色棉布颜色参数和色牢度的影响。结果表明:阳离子改性最佳工艺为阳离子改性剂7%(omf)、氢氧化钠7 g/L、改性温度60℃、改性时间30 min;染液最佳pH值为6。未改性棉织物染色K/S值为5.49、干/湿摩擦色牢度分别为4级和3~4级、防沾色牢度4级;3-氯-2-羟丙基三甲基氯化铵接枝棉织物染色K/S值为6.19、干/湿摩擦色牢度均为3~4级、防沾色牢度4级、Δa*为-1.19、Δb*为0.69、ΔL*为-1.44;双(3-氯-2-羟丙基)四甲基二氯化乙二铵接枝棉织物染色K/S值为11.84、干/湿摩擦色牢度均为3级、防沾色牢度4级、Δa*为-2.00、Δb*为3.70、ΔL*为-5.19。Single and double quaternary ammonium cationic modifiers are synthesized respectively. The chromatic parameters and color fastnesses of modified cotton fabrics are discussed with different modi- fication processes and dyeing conditions. The optimal cationic modification process is： cationic modifier 7%（omf）, sodium hydroxide 7 g/L, modifying temperature 60 ℃, modifying time 30 min, pH value of dyeing liquor 6. Compared with the unmodified fabric, the cationic dyeings feature higher K/S value from 5.49 to 6.19 and 11.84, rubbing fastness from Grade 3-4 to Grade 4, little change in staining fastness. The chromatic parameters of cationic cotton dyeings are △a^＊ -1.19,△b^＊-0.69, △L^＊-1.44 for 3-chloro-2-hy- droxy-propyl-trimethyl ammounium chloride modifier; and △a^＊ -2.00,△b^＊-3.70, △L^＊-5.19 for bi（3-chloro-2- hydroxypropyl） tetramethyl dichloride diammonium ethyl modifier.
