A few days ago, I was started at the Longshan Industrial Park in Longshan Industrial Park. Vice Mayor Yan Tao attended.

According to reports, the supercritical carbon dioxide-free dyeing technology of the Group is in the dyeing medium, and the entire dyeing process is separated from the use of water and chemical aids. It can truly realize no sewage discharge, which promotes the traditional water-printing revolutionary upgrade. And subversive innovation, is a typical green environmental protection technology, with conditions for production. That is, the technology has reached the international leading level, achieving the full color of the dyeing process. Its industrialization application has positive significance for improving the green manufacturing level of my country's textile industry, building ecological civilization and development of low carbon circulation economy.

The industrialization demonstration line started in this operation began trial operation in June 2021. It is a multi-functional energy and process time, etc. There is a significant increase in demonstration lines than in the indicator. At present, the annual production capacity can reach 1000 tons, and the dyeing efficiency can be shortened from traditional water to 3-4 hours to 3-4 hours, and the conditions for industrialization. The industrial line put into production will provide a complete technical and equipment standard specification for the industry, so that my country's supercritical carbon dioxide-free dyeing technology will continue to lead the lead in international.

It is reported that traditional textile staining is mainly water as water, and 100 tons of freshwater resources are required for 1 ton of textiles. At the same time, a large amount of sewage is produced, which seriously restricts the sustainable development of my country's textile industry. Since 2014, the Group has conducted scientific research and research on the supercritical carbon dioxide without water loss process, which has been solved by the universal carbon dioxide-free dyeing process. The related technologies, dyes, equipment and key components have been solved. Key equipment and components such as kettles, including small tests, masonry and industrialization demonstration lines with complete independent intellectual property and continuously run, and overall technology reach the international leadership.
