Traditional textile dyeing industry usually use chemical pigments and dyes, which bring about a large amount of colored wastewater causing serious environmental pollution. Replacing the traditional high pollution dyeing methods to realize eco-friendly dyeing is very important to the textile dyeing industry, structural colorization maybe one of the most promising methods. In this study, a novel approach was proposed to fabricate eco-friendly coloration of textile originating from polydopamine (PDA) structural color nanofilm with high colorfastness. Four different bright colors were obtained by the polymerization of PDA nanofilm with different reaction times on cotton fabric. However, capillary tension during the formation of PDA nanofilm and weak interaction with fabric substrate resulted in cracking and poor colorfastness. The novel synthesis adhesive of poly(glycidyl methacrylate co-polyethylene glycol methyl ether methacrylate) containing reactive epoxy groups was used to avoid cracking and improve the colorfastness which would form covalent bond on the interface between structural color film and substrate. Therefore, crack-free PDA structural color nanofilm with high colorfastness on cotton fabric surface was obtained. This facile approach provide novel idea for eco-friendly dyeing different kinds of textiles with structural color boosting the cleaner dyeing in textile industrial field.

源自聚多巴胺纳米膜结构色且具有高色牢度的纺织品的环保着色

传统的纺织印染工业通常使用化学颜料和染料,这会带来大量有色废水,从而造成严重的环境污染。取代传统的高污染染色方法以实现环保染色对纺织品染色业非常重要,结构染色可能是最有前途的方法之一。在这项研究中,提出了一种新颖的方法来制造具有高色牢度的,源自聚多巴胺(PDA)结构彩色纳米膜的纺织品的环保着色。通过PDA纳米膜以不同的反应时间在棉织物上聚合得到四种不同的亮色。然而,在PDA纳米膜形成过程中的毛细管张力和与织物基底的弱相互作用导致开裂和差的色牢度。新型的含反应性环氧基团的聚(甲基丙烯酸缩水甘油酯共聚乙二醇甲基醚甲基丙烯酸酯)合成胶被用于避免龟裂和提高色牢度,该色牢度将在结构彩色膜和基材之间的界面上形成共价键。因此,获得了在棉织物表面上具有高色牢度的无裂纹的PDA结构彩色纳米膜。这种简便的方法为生态染色各种纺织品提供了新颖的思路,其结构色增强了纺织工业领域的清洁染色效果。获得了在棉织物表面上具有高色牢度的无裂纹PDA结构彩色纳米膜。这种简便的方法为生态染色各种纺织品提供了新颖的思路,其结构色增强了纺织工业领域的清洁染色效果。获得了在棉织物表面上具有高色牢度的无裂纹PDA结构彩色纳米膜。这种简便的方法为生态染色各种纺织品提供了新颖的思路,其结构色增强了纺织工业领域的清洁染色效果。
