Chemical company developed successfully without watermark dyeing equipment
A printing and dyeing equipment that has great significance for energy saving, consumption reduction and environmental protection and emission reduction in China's printing and dyeing industry was successfully developed. The Ministry of Science and Technology announced on March 5 that Dandong Hengxing Fine Chemicals Co., Ltd. has completed the research and development of smart non-watermark dyeing equipment with the support of the national "863" program. According to authoritative inspections, the fresh water consumption of the equipment has been reduced by more than 99.8% over the traditional technology, the sewage discharge is zero, and the comprehensive energy saving is over 60%. The ecological benefit is particularly prominent.
In recent years, the contradiction in the development of ecological recycling economy in China's textile industry has become increasingly prominent. In particular, the high dependence on water resources and the environmental problems caused by high emissions have severely constrained the sustainable development of the industry. According to incomplete statistics, the annual water consumption of China's textile industry exceeds 10 billion tons, fresh water intake ranks second among all industries in the country, and the discharge of waste water ranks sixth in the country, among which the annual consumption of water in the printing and dyeing industry is 1.7 billion tons. The sewage discharge amounted to 1.6 billion tons. Compared with foreign countries, China’s water consumption for textile printing and dyeing is 2 to 3 times that of foreign countries, and energy consumption is 3 to 5 times that of foreign countries.
In view of this situation, the national "863" program gave special support to Dandong Hengxing Fine Chemical Co., Ltd. for the development of intelligent non-watermark dyeing equipment with 1.8m and 2.8m widths with independent intellectual property rights, hoping to pass the research and development of non-watermark dyeing equipment. , Reducing the water dependence and pollution of the printing and dyeing industry.
After two years of technical research, the research team completed the research and development of watermark-free equipment. According to reports, the device omits the complicated steps that traditional printing needs to make plates, realizes direct painting and dyeing on fabrics, applies for 2 national invention patents and 1 international invention patent. Compared with traditional equipment, this equipment has the advantages of short design cycle, simple production process, low cost, high speed, etc. Meanwhile, it also solves the shortcomings of traditional paints with hard hand feel, and is especially suitable for the market requirements of small batches and varieties. What's more, this topic solves the problem of large amounts of water and sewage discharged from dye-printing floating-wash cleansing and traditional process-cleaning rolls. At the same time, the energy consumption index of products is also significantly lower than traditional printing techniques.
The industry believes that this achievement will upgrade the digitalization and greenization technology of domestic printing and dyeing equipment, improve the technical level of textile printing and dyeing production in China, enhance the core competitiveness of printing and dyeing products, promote energy saving and consumption reduction, and reduce environmental protection, and promote the industrial restructuring of the textile industry. The transformation of the growth mode is of great significance.
