摘要/Abstract

摘要： 选用15种具有代表性的分散染料对PLA、PET纤维进行染色。研究了染料在纤维上的颜色特征值和最大吸收波长，发现染料在2种纤维上存在显著的色光差异，与PET纤维相比，染料在PLA纤维上产生了浅色效应，蒽醌型和杂环偶氮型染料在2种纤维上的颜色差别相对较小，较适用于PLA、PET交织物或混纺织物的染色。通过从染料的溶解度参数分析了PLA、PET及染料的相互适应性，提出了PLA/PET混纺系统的染料要求。

Abstract: Polylactic acid (PLA) fiber and polyester (PET) fiber belong to polyester fibers which general be dyed in disperse dyes. Because of the molecular structure and chemical properties of the two kinds of fibers were different, the same dyeing would be shown the color difference phenomenon in fibers. Dyeing PLA, PET fiber with 15 typical disperse dye in papers. The experiment through the dye in the fiber color characteristic value and maximum absorption wavelength showed that significant color different phenomenon in the two kinds of fibers and dye in the PLA fiber produced light effect, and light effect of anthraquinone type and heterocyclic azo type was weaker, anthraquinone type or heterocyclic azo type disperse dye was suitable for PLA, PET woven fabric or blended fabric dyeing. Analysis of the mutual adaptability of PLA, PET and dyes had been given in papers and the dyes suit for PLA/PET blend system was put forward. The result of papers had certain theoretical guiding significance for practice dyeing and the suitable dyes of PLA, PET woven fabric or blended fabric.
