中文摘要:通过对聚乳酸纤维的差热分析 ,了解该纤维的玻璃化转变温度 ,并对 3种不同结构的分散染料作了升温上染速率曲线的测定 ,发现聚乳酸纤维最佳染色温度为 110℃。通过对 12种分散染料的聚乳酸纤维染色性能的研究 ,发现分子体积过小或分子中极性基团过多对聚乳酸纤维上染不利 ,而醋酸酯基的存在似乎能提高分散染料对聚乳酸纤维的亲和力 ,因此具有较高的上染率。

外文摘要:The glass transition temperature was known through the measurement of DSC scan o f PLA fiber.The curve reflected the relation between the dye up-take and dyeing temperature for three disperse dyes with different chemi cal structure, the results show that the optimum temperature of dyeing is 110 ℃.In addition, based on the dyeing characteristic of PLA fiber with 12 kinds of disperse dyes,i t can be concluded that the molecules is too small or there are too much polar g roup in dye molecule,both aren't favorable to dyeing. On the other hand,the pre se nce of acetate group seems to be beneficial to increase affinity of dye for P LA fiber,and thus render higher dye up-take.
