it has entered in five aspects. Innovative: 1Developed a dyeing liquid flow atomizing nozzle suitable for airflow dyeing machine in China; 2Designed and installed a better storage machine slot device (has applied for national patent); 3 Designed and developed a special frequency conversion high-speed fan, Reduced manufacturing costs; 4 developed a new type of cloth roll; 5 developed an advanced full-machine control system - finally successfully developed a novel high-temperature high-pressure airflow dyeing machine in the middle of 2004, after more than a year of production practice. More than ten woven fabrics and knitted fabrics were verified for dyeing process. Basically, it is full of process requirements, and has achieved phased results, making major breakthroughs in energy conservation, emission reduction and emission reduction. Compared with the overflow spray dyeing machine, the average water saving, steam saving and saving aids are all above 50%. 2005. On this basis, the new high-temperature and high-pressure airflow dyeing machine of one tube and two tubes was successfully developed. In October 2006, the optimized design of high-speed fan, storage tank, nozzle, cloth roll and whole machine control system was completed. In December of this year, the design work of technical drawings and tools such as three-tube and four-tube multi-tube airflow dyeing machines was completed. The machine has sold 9 sets (printing and dyeing enterprises in Tianjin, Nantong, Shaoxing, Shandong, Guangdong and other provinces and cities and printing and dyeing factories in Turkey), and passed the national appraisal in August 2007, which is considered to be independent development of foreign advanced technology. Success, various technical indicators have met the design requirements, the technical performance of the whole machine has filled the domestic gap, and the international advanced of similar equipment: the successful development of the machine provides advanced and reliable high efficiency, energy saving, low pollution and high automation degree for the printing and dyeing industry. The new equipment can replace imported, providing guarantee for the technical transformation, equipment renewal, investment reduction, foreign exchange saving, energy saving and emission reduction of printing and dyeing enterprises.
