The working principle and application of dyeing machine
1. Technical Principle 1. Technical Principle According to the principle of aerodynamics, the water mist-like dye liquor produced by the special nozzle is dyed with the dyed fabric in the air-liquid mixing room, and the dyed fabric is drawn by the circulating airflow for cyclic movement. 2. Key technology Dyeing liquid nozzle, gas-liquid mixing chamber, circulating fan, variable cross-section storage tank, dyeing liquid distribution system, dyeing liquid temperature control system, flow control system, feeding control system, etc. 3. Process flow Pre-treatment (desizing, scouring, bleaching, alkali reduction) → dyeing → post-treatment → softening and finishing 2. Technology application The high-temperature and high-pressure airflow dyeing machine, after eight years of concentrated research and technical tracking by R&D personnel, it has developed almost synchronously with the contemporary airflow dyeing technology, and obtained a large amount of experimental data of dyeing process, laying a solid foundation for the successful development of this technology. . It has been used for trial production in many printing and dyeing factories in Guangdong, Jiangsu and other places. Compared with ordinary overflow or jet dyeing machines, it can save 50% of water, 50% of steam, 10%-15% of dyes, and 60% of additives. , Pollution discharge is reduced by 50%. In addition, airflow dyeing has less tension on high-stretch knitted fabrics (including spandex), and the processed fabrics feel higher than ordinary overflow or jet dyeing. It has been verified by practice that in the airflow dyeing process, there is a mutual rubbing condition between the fabrics, which is suitable for the completion of the "primary and secondary fibrillation" process of Lyocell [tencel] fiber fabrics, enzyme biochemical treatment, and sea-island fineness. The alkali dissolution of the fiber leaves the fiber and other new processes.
