my country’s acid dye market is relatively mature and there are few opportunities for future development.

Acid dyes, also known as anionic dyes, mainly have azo and anthraquinone structures, and a few products have aromatic methane structures. Acid dyes are more suitable for protein fibers, nylon fibers, silk, etc. For dyes with different properties, different acids or acid salts should be used. The higher the acidity of the dyeing solution, the faster the coloring speed, and the more color-absorbing liquid will eventually be absorbed. The uniformity and durability of dyes can be achieved through the input ratio. The amount and selection of acid are the core competitiveness of enterprises in the acid dye industry.

Since global dye production shifted from the United States and Europe to China at the end of the last century, China has become the world’s largest producer, consumer and exporter of dyes. my country is the world’s largest producer and exporter of dyes. The dye fine chemical industry chain and supporting system are mature and complete, providing many favorable conditions for the development of my country’s dye intermediate industry. At present, our country can produce about 2,000 kinds of dyes, and produces thousands of dyes all year round, of which acid dyes are an important category.

According to the“China Acid Dyes Market Analysis Feasibility Research Report 2021-2025” released by the Industrial Research Center, with the environmental protection policy The tightening of regulations, the investment pressure on environmental protection technology reform has increased, backward small dye production enterprises have been gradually phased out, the supply of dyes has shrunk, and the output of acid dyes has declined overall. In 2020, my country’s total dye output was 770,000 tons, of which 60,000 tons were acid dyes, accounting for a relatively small proportion of the overall dyes.

In terms of import and export, domestic acid dye production continues to decline, but the demand for acid dyes is relatively high, requiring a large amount of imports to meet domestic demand, and exports show a steady downward trend. In the first three quarters of 2021, the epidemic was effectively controlled, and my country’s acid dye export volume gradually recovered, reaching 1.2 tons, a year-on-year increase of 40%, and the export volume reached 0.9 tons, a year-on-year increase of 14%. At present, the production capacity of the domestic acid dye industry is mainly concentrated in Jiangsu, Zhejiang, Shandong and other provinces and cities. It mainly includes enterprises such as Zhejiang Longsheng and Anoqi. Zhejiang Longsheng has a production capacity of 5,000 tons of acid dyes. In addition, Jihua Group has a production capacity of 7,500 tons of acid dyes, and Yueqing Chemical Technology Co., Ltd. has a production capacity of 3,000 tons.

With the development of the market, under the guidance of national industrial policies, environmental protection policies have become more stringent. Green, environmentally friendly, differentiated dye products that meet high-end needs will become the future development direction. my country’s large-scale acid dye enterprises have gradually established the concept of comprehensive ecology, environmental protection and health, increased investment in comprehensive environmental protection, constantly improved production equipment and technology around energy conservation and emission reduction, combined with their own actual absorption of high-tech achievements, and continued to promote clean production of acid dyes Preparation technology to reduce pollutants such as wastewater and COD.

Industry analysts said that acid dyes are one of the important components of dyes. However, in recent years, the domestic textile industry has been in recession, and acid dyes have Market demand has shrunk. However, from the perspective of import and export, my country’s acid dye imports are higher than exports, and both imports and exports will show a growth trend in 2021. Generally speaking, my country’s acid dye market is relatively mature and has relatively small opportunities for future development.
