|
随着社会的进步和人们生活水平的提高，人们对织物的外观和穿着舒适度的要求越来越高，因此对织物进行功能整理显得尤其重要。染色后整理使用的功能助剂不仅对织物要有较好的整理效果，如固色、防皱、耐洗、抗静电、抗紫外线等；而且要求无毒，对环境无污染。所以寻求高性能且环保的织物功能助剂始终是染整行业研究的热门课题。 本论文研究的主要内容：(1)采用异佛尔酮二异氰酸酯、聚乙二醇、聚丙二醇、二羟甲基丙酸、三乙胺、亚硫酸氢钠等为主要原料合成了系列水性聚氨酯功能助剂并表征其相关分子结构；(2)采用二甲基二烯丙基氯化铵和N,N-二甲基烯丙基对苯甲酰苄基溴化铵对水性聚氨酯进行改性合成了两种改性水性聚氨酯功能助剂并表征其相关分子结构；(3)将所合成的系列水性聚氨酯功能助剂应用于不同活性染料的染色织物进行固色等功能整理并测试了其相关效果。 研究结果显示：(1) 所合成的系列水性聚氨酯功能助剂不含甲醛，确定了合成稳定的水性聚氨酯乳液的条件：DMPA用量为4%，中和温度为40℃，中和度为100%；R值在1.6-2.0之间有利于获得外观和稳定性较好的乳液。 (2) 根据所合成的水性聚氨酯功能助剂对织物整理效果的影响，确定了最佳的合成条件：R=2.0，封端剂用量为6.5%，环氧氯丙烷用量为5.5%，PH=6。 (3) 根据水性聚氨酯功能助剂的应用工艺参数对织物整理效果的影响，确定了最佳的整理工艺：功能助剂用量4%，烘焙温度为140 ℃，烘焙时间为1.5min，整理液温度为50 ℃，时间为30 min，轧余率为100%。 (4) 用合成的二甲基烯丙基氯化铵对水性聚氨酯进行改性，确定了适宜的合成条件：n(单体1)：n(单体2)=1:2，引发剂NBS用量为1%，并确定了其对织物的较优整理工艺：功能助剂用量为3%，烘焙温度为130℃，整理液pH为6，整理液温度为50 ℃，时间为30 min。 (5) 用合成的N,N-二甲基烯丙基对苯甲酰苄基溴化铵对水性聚氨酯进行改性，确定了适宜的合成条件：n(单体1)：n(单体2)=1:2，引发剂NBS用量为1%。并确定了其对织物的较优整理工艺：功能助剂用量为3.5%，烘焙温度为140℃，整理液pH为6，整理液温度为50 ℃，时间为30 min。 研究结果表明，所合成的功能助剂对不同的活性染料染色的织物均有较好的整理效果，而且N,N-二甲基烯丙基对苯甲酰苄基溴化铵季铵盐改性水性聚氨酯功能助剂具有良好的吸收紫外线功能。 |

With the social progress and the improvement of living standards of the people , the increasingly high demand for fabric appearance and wearing comfort , functional finishing of the fabric is especially important . After dyeing , finishing functional additives used not only for the fabric to have a good finishing results , such as solid color , crease-resistant , washable , anti-static , anti- UV ; and requirements of non-toxic , pollution to the environment . So seeking a high-performance and environmentally friendly fabric functional additives is always a hot research topic of the dyeing and finishing industry . The main content of this thesis : (1) different isophorone diisocyanate , polyethylene glycol, polypropylene glycol , dimethylol propionic acid , triethylamine , bisulfite sodium as the main raw material for synthesis of a series of water-based polyurethane functional additives and characterization of its associated molecular structure; (2) of dimethyl diallyl ammonium chloride and N , N - dimethyl- allyl change benzoyl benzyl ammonium bromide , water-based polyurethane synthesis of two modified waterborne polyurethane functional additives and characterization of its molecular structure ; (3) the synthesis of a series of waterborne polyurethane functional additives used in fixing functions of different reactive dyes dyeing fabric finishing and test its related results.
