Changzhou Jun Hong introduced cold rolled pile dyeing technology can save 90% Recently, the China Textile Industry Association, Science and Technology Department organized experts in Changzhou, Jiangsu Jun Hong Dyeing Co., Ltd. held "on the use of cold yarn dyeing method" project Identification meeting. An innovative yarn dyeing technology has aroused widespread concern in the industry. By Changzhou Junhong Dyeing and Finishing Co., Ltd. independent research and development using cold-rolled yarn pile dyeing method, the traditional warp-tube dyeing can dye every 1 ton of yarn consumption of 120 to 160 tons of water, down to about 13 tons of water per ton of yarn consumption , Saving more than 90%. At the meeting, experts agreed that the project broke through the traditional cheese, yarn intermittent dip mode, to achieve a semi-continuous dyeing process cold-rolled heap yarn, yarn dyeing technology is a major innovation. The technology has obvious effects in saving water, saving electricity and reducing labor cost, and the product quality is stable. The project has obvious energy-saving emission reduction effect and good economic and social benefits, in line with the trend of social development, marketing broad prospects. Project achievements reached the international advanced level. According to reports, the traditional cotton yarn dyeing dyeing method has been adopted cheese yarn and warp beam dyeing yarn, Changzhou Junhong project using cold rolled pad dyeing method, from intermittent to semi-continuous. This method for the first time at home and abroad with pad dyeing, but also for the first time the cold pad pile technology applied to the dyed. At present, the project has applied for seven patents (three inventions, four practical), and are accepted, of which two utility patents have been certified. Yang Lixin, chairman of Changzhou Jun Hong, is very confident about this project. He said that the technology will become Changzhou Jun Hong new economic growth point. Changzhou Jun Hong in 2007 designed this set of cotton yarn cold rolling pile dyeing process equipment. December 2007, China Cotton Textile Industry Association organized experts to demonstrate the project, affirmed the feasibility of the project and development prospects. In November 2008, China Textile Industry Association set the project as a science and technology guidance project. Yang Lixin introduction, in the current context of building environmentally friendly, resource-saving society, the technology has many advantages. The first is a drastic reduction in sewage discharge. At present, the warp-bobbin dyeing method consumes about 120 to 160 tons of dyed yarns per ton of yarn. After this method, each ton of yarn dyed consumes about 13 tons of water. Second, less energy consumption, lower costs. Compared with the existing equipment, this equipment can reduce the consumption of water, electricity, steam, dye materials and labor resources by more than half. The existing dip equipment production costs, including water, electricity, dyes, wages, etc., is generally 8500 yuan / ton. The production cost of using the device is about 3,500 yuan / ton. Third, equipment investment is low. This technology a set of equipment investment of about yuan, according to the normal driving calculation of 16 hours a day, dyeing yarn 15 to 25 tons, while the same production of cheese, warp beam equipment investment in more than 50 million yuan. Fourth, simple operation. The use of the equipment does not require control of temperature, time, bath ratio, sodium sulfate and soda ash dosage, but only need to control the concentration of dye and speed. In addition, the yarns that have been tested using this technology have reached the international requirements for the color fastness (white cloth staining and rubbing fastness) and are suitable for mass production of small-batch multi-color dyeing machines. They have also been patented Complete the drawings, can develop multi-color dyeing, chemical fiber (blended) yarn dyeing, mercerizing continuous dyeing and other projects.
