Abstract

The primary function of dyes is to color items. Textile dyes are generally used for dyeing textile products and can be categorized into natural and synthetic types, with synthetic dyes gradually becoming the focus of research and use. The structure and properties of different fuels vary, so in order to open up international markets and keep pace with their development, enterprises across the country are focusing on fuel innovation and development as their main research direction. Currently, the main research directions are centered on green textile dyes and new resource fuels, with reactivity and dispersion being the primary topics of research worldwide.

In the last century, the continuous growth of the population and industrial development have destroyed the diversity of ecosystems that organisms rely on for survival. Among them, the pollution of marine and river ecosystems is mainly caused by the discharge of inadequately treated industrial wastewater. Many industries, such as dyeing, textiles, plastics, paper, food, cosmetics, and pharmaceuticals, widely use dyes for coloring while consuming large amounts of water, resulting in a significant amount of dyeing wastewater.

Textile DyesDyes are classified according to the chemical structure of their chromophore groups into azo, anthraquinone, triphenylmethane, heterocyclic, and polymeric types. Many dyes can cause discoloration of water at a concentration of 1mg/L.Textile DyesIn wastewater, the concentration of azo dyes ranges from 5-1500mg/L, which intensifies the color of the water, reduces its transparency, decreases photosynthesis, dissolved oxygen levels, and water quality, causing acute toxicity to aquatic organisms and adversely affecting the TOC and COD of the water. On the other hand, many dyes and their metabolites are toxic, carcinogenic, and mutagenic, posing potential health risks to humans and damaging ecosystems. Therefore, textile dye wastewater is a focus and challenge in industrial wastewater treatment.

The role of dyes themselves is to color items. Among them,Textile Dyesthey are generally used for dyeing textile products, and can be divided into natural and synthetic types, with synthetic dyes gradually becoming the focus of research and use. The structure and properties of different dyes vary, so to open up international markets and keep pace with international market development, enterprises across the country are focusing on innovation and development of dyes. Currently, the main research directions are green textile dyes and new resource fuels, with reactive and disperse dyes being the primary focus of research worldwide.

Currently, the types developed in our country mainly focus on reactive dyes with dual reactive group characteristics, which align with the concepts of environmental protection and energy saving. The main applicable ranges are: (1) medium temperature; (2) low salt; (3) RFT; (4) small bath ratio. In the past two years, with the continuous strengthening of global environmental protection and sustainable development regulations, there has been a gradual abandonment of the use of polluting dyes made from harmful chemicals, and a series of regulations have been established regarding the use of metal complexing flame retardants. These measures have made reactive dyes gradually become the focus of attention, with their corresponding production increasing to 0.5% to 0.8% of the total. People have summarized the process of developing and using dual reactive group dyes, while promoting and developing reactive dyes related to indirect proteins and fibers. Currently, dye production enterprises across the country are beginning to pay attention to this.Textile Dyesand are starting to attempt corresponding research and production. Thus, domestic dyes meet the requirements for color fastness and environmental protection.
