In traditional textile printing and dyeing technology, about 50 tons of water are used to dye and wash one ton of polyester cloth. To
According to industry analysis data, the wastewater discharge of the textile printing and dyeing industry accounts for about 11% of the national wastewater discharge, 2 billion to 2 billion 300 million tons per year. "Green water and green mountains are golden mountains and silver mountains." How to make this industry move in a more environmentally friendly direction? To

Lianyungang Yingyou Xinlicheng Textile Technology Co., Ltd. gave a possibility. The flash dyeing technology they developed reduced the “50” to “2”. Walking into the factory building of Xinlicheng Textile Technology Co., Ltd. located in the high-end textile industrial park of Guanyun Economic Development Zone, the ground is clean and fresh, no trace of water can be seen, only the natural smell of the heated cloth in the air, and the entire roll of pure white fabric flashes One end of the dyeing production line equipment is fed in, pulled by the machine, and rolled forward at a speed of 65 meters per minute. When passing through the pad dyeing unit, it is instantly colored under the action of high temperature as high as 200 ℃, and then dried and fixed. On the other end, the finished goose-yellow fabric rolled out smoothly, without using a drop of water throughout the process. And this set of technologies and equipment are all independently developed. It can be said that this is a revolution in the printing and dyeing industry, and it is also of great significance to environmental protection. To

Waterless printing and dyeing is the dream goal of the printing and dyeing industry all over the world. Since the end of the last century, countries have invested a lot of manpower and material resources, but they have not been able to develop a way to quantify production. To

Zhang Guizhen told reporters that the previous research direction of waterless printing and dyeing was to find a medium to replace water, but this method is always inseparable from traditional dyeing materials. One is that a large amount of water is consumed in the process of vat dyeing, and the other is The printed and dyed fabric must be washed with water.

The R&D team used color paste instead of water, used the principle of high-temperature instant dyeing of polyester fabrics as a breakthrough, and constantly improved and perfected the hot-melt dyeing process. At the same time, it broke the traditional thinking. The problem. To

It's simple to say, but the process of tackling key problems is full of hardships and twists, with problems one after another, how to design the equipment? Where can I find dyes? How to strengthen the color fastness? How to solve uneven dyeing? To

Eagle Tour Group has pooled the power of the entire group to invest in research and development. The R&D personnel put forward ideas, and the textile machine designs drawings and manufacturing equipment at the rear. The experimental department continuously polishes every data, produces a first-line trial production, and returns to the results before proceeding to the next round of R&D. "In the textile industry, equipment is first. Without equipment, it is like cooking without a pot, but it is difficult to have a completely open window for seeking cooperation. With the hard work of all employees, they achieved the first step of success. In May 2017, they developed the first The flash dyeing complete equipment production line integrates pre-forming, padding, pre-drying, drying and fixing, and cooling arrangement. Compared with the traditional process, it eliminates the four processes of washing, dehydration, cloth arranging, drying and setting. Greatly improve production stability and efficiency.

But what follows is the problem of dyes and chemicals. There are a large number of dispersing agents, suspending agents, flexibility agents, thickeners, etc. in the past dyeing materials. "There are dozens of ingredients that are ineffective for actual dyeing, accounting for more than 70% of the dyestuffs. We provide the largest dyestuff in the country. Manufacturers are seeking cooperation to develop dyes with almost no additives." As soon as they heard this demand, the technicians of the dye manufacturers laughed, "This is impossible!" Zhang Guoliang decided, "You will test, but I will fail the products. Buy it." This allowed the manufacturer to agree to research and development. To

Sharpen a sword in seven years. Nowadays, the flash dyeing technology has shown its brilliance in China. Xinlicheng has obtained 8 patents in the research and development process, and 8 patents are still being applied for. It has core independent intellectual property rights and its technological level has reached the international leading level. "Our production cost has been reduced from 3,700 yuan per ton of cloth to 1,600 yuan. Now, four production lines produce 120 tons of fabric per day, requiring only more than 100 workers. In traditional production methods, such output requires at least 400 workers. From an environmental perspective In the past, the COD value of each ton of wastewater was as high as two to three thousand. Now only some water is needed to clean the machine and the treatment of dark cloth. The water consumption has been greatly reduced, and the COD value has also dropped to several hundred. It is easier to treat and pollutes. Smaller." Sun Sumei said, the cloth they produce is in short supply in the market, and they are continuing to tackle the final "2" and strive to achieve complete "waterless printing and dyeing" as soon as possible. To

After the world economic model has experienced industrialization and informatization, it is gradually moving towards a "low-carbonization" process, which means that the "low-carbon economy" will become the key to national competitiveness and corporate competitiveness in the next 40 years from now to 2050. Important manifestation. To
For the textile printing industry, whether it is the gradual maturity of domestic technology or the strong introduction of foreign advanced technology, it clearly reveals that under the background of sustainable development of energy conservation, emission reduction and environmental protection, the current domestic textile printing and dyeing industry is bound to In the near future, it will usher in a critical window period for the overall transformation and upgrading of the industry.
