五大印染技术（Five printing and dyeing technology） Silk industry: efforts should be made to develop five major printing and dyeing technologies January 8, 2002 Development and trend of comprehensive domestic and international silk printing and dyeing technology, experts believe that the four must be around the theme of the development of silk products of high quality and high efficiency, energy saving, environmental protection to the development of silk dyeing technology for silk reducing wrinkle easily, easy to fade, yellowing three defects, to overcome this three defects is not easy. The improvement of silk production process is based on four objectives: good, fast, save and green. Efforts should be made to develop the following technologies: First, cold rolling pile silk refining technology. Cold rolling batch technology has been successfully used in cotton dyeing and printing with reactive dye dyeing and cotton desizing. The advantages of water saving and energy saving of cold rolling reactor are very obvious, and it has been widely welcomed and widely used by printing and dyeing enterprises. Some people in China have been researching and transplanting this technological idea to the silk degumming and refining process. If will come up this technology applied to silk production process, not only can save a large amount of water vapor and oxygen, but also can greatly reduce the traditional refining equipment of silk caused by ash injury, lifting India, India wrinkle defects, to energy saving and environmental protection, improve the quality of the products will be of great benefit. Tests have shown that in the temperature of 35 degrees Celsius, thin, weft dense Satin 24 hours to complete the degumming (traditional process needs high temperature 96-98 degrees Celsius, micro boiling conditions under repeated refining can be completed, it takes more than 5-10 hours). Thick, high density of weft Satin takes 96 hour to reach about 23% of the degumming rate, from the practice
