靛蓝清洁染色技术的研究进展
Research progress in indigo clean dyeing technology
摘要
Abstract
In response to the environmental issues caused by the use of indigo dyes,the development of clean indigo dyeing technologies has become a focal point of research.In recent years,technologies such as green reducing agents for indigo,electrochemical reduction,biological reduction of indigo,indigo foam dyeing without oxygen,in-situ dyeing,nitrogen-protected dyeing,and non-aqueous medium dyeing have been developed.This article reviews the principles,development,and challenges of these technologies and provides an outlook for future indigo clean dyeing technology. The review found that one of the major challenges in developing green alternative reducing agents lies in identifying reducing agents that can match the high reduction potential of indigo and activate its reducing capacity,while ensuring recyclability.Biological reduction technology is still in its early stages and requires improvements in the catalytic efficiency of enzymes or cells,along with considerations of their stability,reusability,adaptability to the environment,and specificity,to meet the needs of industrial production.In electrochemically reducing indigo,improving reduction efficiency,current efficiency,and rate,as well as controlling hydrogen evolution side reactions,are crucial for the application of this technology.Additionally,addressing the separation and recovery of mediators in indirect electrocatalytic reduction is crucial for reducing material loss and enhancing economic and environmental benefits.Some of the core innovations in other novel indigo clean dyeing methods focus on precisely controlling the early oxidation process of indigo leuco dye or abandoning the traditional reduction-dyeing mechanism.These innovations not only significantly reduce resource consumption but also greatly enhance dyeing quality.However,in practical applications,these advanced technologies still face a series of challenges. Looking forward,advancements in mechanical and chemical engineering will bring innovative opportunities for clean indigo dyeing.Indigo clean dyeing technology is expected to integrate electrochemical reduction,biological reduction,green reducing agents,and pre-reduced indigo products to form environmentally friendly and efficient solutions.At the same time,methods for controlling the early oxidation of indigo leuco dye and dyeing in non-aqueous media will be further optimized to enhance dyeing effects.On the other hand,process optimization and cost control will be key focuses of future research.Although new methods are environmentally friendly and have shown promising results in industrial demonstrations,equipment costs,operational complexity,and market acceptance remain challenges for their widespread adoption.Future research will concentrate on process optimization to reduce the use of water,energy,and chemicals,so as to reduce costs and promote the widespread application of clean dyeing technology to achieve a green transformation in indigo dyeing.关键词
