The Bright Chemical Research and Design Institute, which has been engaged in the research and development of supercritical carbon dioxide extraction technology for many years, has taken the lead in the development of dyeing technology and made new progress in China. Guangmingyuan is currently developing an industrialized supercritical carbon dioxide dyeing device and has established an industrial demonstration project for supercritical carbon dioxide dyeing.
In the development of the supercritical carbon dioxide dyeing process, Bright House uses a large-volume self-circulating system and a unique high-pressure dyeing kettle structure. After conducting a variety of studies on the structure of the barrel in the high-pressure dyeing kettle, the solubility of disperse dyes in supercritical carbon dioxide under different temperature and pressure, and the determination of the optimum coloring process conditions, they have now provided the Hong Kong Productivity Council with synthetic fiber super. The critical carbon dioxide extraction dyeing machine developed a natural fabric supercritical carbon dioxide dyeing facility for Dalian Light Industry College.
Since the 1990s, Germany has taken the lead in studying supercritical fluid dyeing technology and invented a number of patents. It has developed a printing and dyeing process using supercritical carbon dioxide as a medium, using disperse dyes on fiber textiles, and providing high pressure suitable for synthetic textile printing and dyeing. Pilot plant. Subsequently, the United States, Japan, Korea, etc. have also conducted research and development on the industrialization of supercritical dyeing technology. The use of supercritical carbon dioxide as a dyeing solvent not only saves a lot of water resources, but also fundamentally solves the problem of water pollution in the printing and dyeing industry. Carbon dioxide can be recycled and dyes can be recycled 100%.
Supercritical carbon dioxide dyeing technology is good for the dyeing of man-made fibers and natural fibers. China is a big producer of textiles and a major exporter of textiles. The industrialization of anhydrous dyeing of supercritical carbon dioxide as soon as possible will help improve the overall level of the textile industry. Guangming Institute’s scientific research personnel through a small pilot study, the pilot scale amplification experiment and the industrialization practice of production equipment, out of a scientific research, design, production, installation, commissioning, training integrated technology development road, and continuous innovation and development.
