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。
15 typical disperse dyes were selected and applied to the dyeing of PLA and PET fibers. The color characteristic value and maximum absorption wavelength of the two fibers were examined and significant color difference was shown between the two fibers. Light shade effect displayed on the PLA fiber when compared with PET. Less color difference was shown between the two fibers when they were dyed with anthraquinone type and heterocyclic azo type dyes which were more suitable for dyeing PLA, PET union fabrics or blended fabrics. Having analyzed the properties of PLA and PET as well as the compatibility of dyes, the dyes suitable for PLA/PET blend system was put forward.
