【摘要】 本文采用高取代度季铵型阳离子淀粉、氨基烯烃聚合物以及紫外线吸收剂BP-4接枝氨基烯烃聚合物作为阳离子化试剂对棉纤维进行物理改性,用于活性染料无盐竭染。阳离子淀粉中的季铵基团和氨基烯烃聚合物在一定pH范围内形成的盐酸盐为起到促染作用的阳离子基团。阳离子化棉纤维用于活性染料染色不添加无机盐,固色率可达到或高于传统有盐染色的固色率,在解决活性染料染色中盐污染问题的同时提高了染料的利用率。 以高取代度阳离子淀粉作为棉纤维阳离子化试剂,采用浸轧-焙烘工艺对棉纤维进行阳离子化,考察了预处理工艺条件对染料固色率的影响;染色结果表明染料固色率与有盐染色相当,但匀染性差;通过超声波降低阳离子淀粉粘度,棉纤维染色匀染性提高,但提高固色率有局限。 以高取代度酸降解阳离子淀粉作为棉纤维阳离子化试剂,分别采用浸润和浸轧-焙烘工艺进行预处理,用于活性染料无盐染色。考察了预处理条件对阳离子淀粉在棉纤维上吸附量及染料固色率的影响;探讨了促染机理,对比了有盐和无盐染色工艺中染料固色率、色光、色牢度、整理功能及渗透性;考察了降解阳离子淀粉循环使用情况。 以聚乙烯胺和聚烯丙基胺作为棉纤维阳离子化试剂,分别采用浸轧.焙烘和浸润工艺对棉纤维进行改性,用于活性染料无盐染色,考察了浸润工艺预处理条件对聚乙烯胺在棉纤维上吸附量及染料固色率的影响;探讨了促染机理,对比了有盐和无盐染色工艺中染料固色率、色光、色牢度、整理功能及渗透性;以聚乙烯胺为例,考察了它的循环使用情况。 采用氯化亚砜为氯化试剂和溶剂,DMF为催化剂,对紫外线吸收剂BP-4进行了磺酰氯化反应,合成了相应的磺酰氯化合物;利用核磁共振氢谱、红外光谱和质谱表征了所合成的磺酰氯的结构,结构正确。 利用氨基烯烃聚合物分子链上氨基的反应性及同一分子链上存在多个可反应基团的优点,采用氯磺化BP-4分别与聚乙烯胺和聚烯丙基胺反应得到了含二苯甲酮结构的具有紫外吸收功能的氨基烯烃聚合物PVAmBP-4和PAAmBP-4,并将它们作为阳离子化试剂用于活性染料无盐染色,考察了染色性能及纤维抗紫外整理功能。更多还原

【Abstract】 Cationic starch of quaternary ammonium type with high DS, polyamines and polyamines grafted with UV-absorber BP-4 were applied as cationic agents of cotton in salt-free dyeing of reactive dyes. Quaternary ammonium groups of cationic starch and aminocations within polyamines in a wide range of pH were functional groups for dye adsorption. High fixation was achieved in salt-free dyeing, and pollution problem resulted from salt usage in conventional dyeing process was solved.Dip-pad-bake process was employed in pretreatment of cotton with native cationic starch with high DS. Influence of pretreatment conditions on dye fixation was investigated. The results showed that good dye fixation compared with that of conventional dyeing was obtained, but level dyeing was not achieved. Ultrasonic was used to reduce viscosity of native cationic starch to improve levelness of dyeing, but unsatisfactory dye fixation was got.Cationic starch hydrolyzed by hydrochloric acid was then applied;dip-rinsing process and dip-pad-bake process were used for pretreatment of cotton. Effect of pretreatment conditions on both adsorption amount of cationic starch and dye fixation was examined. Dyeing mechanism was discussed and the performances (including color, fastness, finishing properties and dye penetration) of the dyed cotton fibers were investigated. Recycle utilization of cationic starch was also examined.Polyvinylamine and polyallylamine were applied in pretreatment of cotton in salt-free dyeing process. Dip-pad-bake and dip-rinsing processes were used for pretreatment of cotton. Effect of pretreatment conditions on both adsorption amount of polyvinylamine and dye fixation was examined. Dyeing mechanism was discussed and the performances (including color, fastness, finishing properties and dye penetration) of the dyed cotton fibers were investigated. Recycle utilization of polyvinylamine was also examined.Chlorosulfonyl-containing UV absorber CBP-4 was synthesized by the reaction of the corresponding UV absorber BP-4 and thionyl chloride in the presence of a catalytic quantity of DMF. Its structure was confirmed by IR, ~1H NMR and MS spectroscopies.Two BP-4 grafted polyamines-PVAmBP-4 and PAAmBP-4 were synthesized from the prepared CBP-4 and their applications including effect on dye fixation and transmissivity of cotton were investigated.更多还原
