摘　　要：本文合成了三支含有PEG作为间隔基的遥爪聚合物型阳离子活性染料,并考察了该染料对棉织物的无盐染色性能。结果表明,竭染率和固色率分别在85%和75%以上,对纤维素纤维具有良好的亲和性;染料的干摩擦色牢度均达到4~5级,耐光色牢度达到5~6级;BCD-Y皂洗牢度3~4级,其他两支染料的皂洗牢度达到4~5级。In this paper, three telechelic polymeric cationic reactive dyes which contain PEG as spacer group were synthesized, and their salt free dyeing properties on cotton fabrics was researched.The results showed the dyes possessed good substantivity to cellulose fiber.The exhaustion and fixation of dyes in salt free dyeing was above 85% and 75% respectively.The color fastness to dry rubbing of three dyes reached grade 4-5 and their color fastness to light reached grade 5-6.Their color fastness to washing with soap or soap and soda also reached grade 4-5,except the dye BCD-Y(grade 3-4).
