随着现代社会可持续发展和公众健康意识的日益增强，环保型染色工艺在纺织行业引起了极大的关注。禁止在着色过程中使用天然着色剂时使用有毒重金属媒染剂。本研究开发了一种在多巴胺存在下，天然着色剂在各种合成纺织材料上的环保型着色工艺，其原位自聚反应可以产生丰富的多酚着色剂。利用该方法，各种合成纺织材料可以很容易地用天然着色剂以简单的工艺进行着色，特别适用于那些难以着色的材料。与对照工艺相比，合成纺织材料具有更好的天然着色剂上染率，其色泽更深，K/S值更高。对着色材料进行了比色分析、扫描电子显微镜和光学显微镜分析，也证实了所提出的着色工艺的成功应用。此外，拟议的策略还可以应用于各种材料。它是纺织材料领域的一种创新的绿色着色工艺。
With the increasing awareness of sustainability development and public health in the modern society, environmentally-friendly coloration process draws tremendous attention in the textile industry. Toxic heavy metal mordants are forbidden to be used in the application of natural colorants in the coloration process. In this study, an environmentallyfriendly coloration process with natural colorants on various synthetic textile materials was developed in the presence of dopamine, whose in-situ self-polymerization could produce rich polyphenolic coloration anchors. Using the proposed method, various synthetic textile materials could be easily coloured with natural colorants in a simple process, which is especially suitable to those materials which are difficult to be colored. Compared with the control process, synthetic textile materials were endowed with better exhaustions of natural colorants, as verified by their deeper colour appearance and higher K/S values. The colored materials were also characterized by colorimetric analysis as well as scanning electron microscopy and optical microscopic analysis, which also confirmed the successful application of the proposed coloration process. Moreover, the proposed strategy could also be applied on a wide variety of materials. It is an innovative green coloration process in the textile material fields.
