Made in China, creating a big country; no watermark dyeing, decorating the blue water and blue sky. On November 3, the subversive traditional watermark-free dyeing technology appraisal meeting was held in Dongguan. The appraisal meeting was jointly organized by China National Textile and Apparel Council and China Environmental Protection Industry Association. After identification, the continuous dyeing technology and equipment for disperse dyes developed by Dongguan Jinyinfeng Machinery Industry Co., Ltd. reached the international leading level.
The textile industry is an important component of the national economy. In the 40 years of reform and opening up, China's textile production has accounted for about 60% of the world. However, the traditional textile printing and dyeing process has brought huge environmental pollution. According to the 2015 Annual Report on Environmental Statistics, among the 41 industrial sectors, textile wastewater discharge ranks third, accounting for 10.1% of total emissions, and aerobic emissions ranks fourth, accounting for 8.1% of total emissions. . The textile industry has become the hardest hit by China's pollution. Faced with the grim situation, textile printing and dyeing urgently needs technological innovation, and it is expected to realize the implementation of subversive water-free dyeing technology.
Dongguan Jinyinfeng Machinery Industry Co., Ltd., as a brave pioneer and pioneering pioneer, was founded in 1994. It is a coating and laminating machine and printing and dyeing machine for research and development of textiles, artificial leather and other fields. National high-tech enterprises, 80% of products are exported to Europe, South America and Southeast Asia, Middle East countries.
Since 2013, “Jinyinfeng” has relied on 20 years of technical accumulation, and has focused its attention on the highest level of technology in the global printing and dyeing industry – the “three noes” cleaning and dyeing technology with no water and no carbon, and has begun to explore and invent. A new low-cost cleaning and dyeing process system that is completely different from traditional printing and dyeing processes and supercritical carbon dioxide dyeing technology.
The traditional printing and dyeing process consumes about 140 tons of water per ton of fabric produced, resulting in about 98 tons of sewage discharge. The annual discharge of printing and dyeing wastewater exceeds 2 billion tons.
Material innovation: research and development of nano-scale liquid dyes and fiber fast swelling additives.
The watermark-free dyeing machine developed by “Jinyinfeng” only needs about 0.5 tons of water for each piece of fabric produced, and there is no waste water and waste residue discharged. Compared with the traditional process, the water saving is over 99.5%, the process investment is saved by 40%, and the operating cost is saved by 30%. Compared with CO2 dyeing technology, it also shows great advantages of low cost, high output and high return. The dyeing, fixing and setting process completely realizes the integrated clean production with low cost, low energy consumption and no pollution. In October 2018, the new fourth-generation waterless low-carbon and low-emission continuous printing and dyeing equipment was unveiled at the Shanghai Textile Machinery Exhibition.
Equipment innovation: research and development of waterless non-discrete printing and dyeing equipment system.
At the scene of the technical achievement appraisal meeting, Wu Xianglin, deputy director of the Dongguan Environmental Protection Bureau pointed out that the water-free dyeing technology developed by “Jinyinfeng” has filled the gap between the international and the domestic, greatly subverting the tradition, and is completely different from the traditional printing and dyeing process. The new low-cost clean printing and dyeing process system of supercritical carbon dioxide dyeing technology is a new low-cost, low-energy, pollution-free integrated clean production technology, which is very important in water conservation, environmental protection, energy conservation and emission reduction. Economic and social values.
Process innovation: research and development of high temperature breathing dyeing process.
Wu Meiliang, deputy director of the Dongguan Municipal Science and Technology Bureau, commented that this technology is a major independent innovation achievement, and is the original technology of the world printing and dyeing industry. It is a technology that cannot be bought with money. The breakthrough of this technology is not only a high level of printing and dyeing in China, but also a great contribution to China's economic and social development. It not only reduces the production costs of printing and dyeing enterprises, but also enables users to obtain benefits. Moreover, due to its powerful water-saving and emission reduction and pollution reduction capabilities, it will surely exert enormous economic and social benefits for China's economic and social development!
In the past five years, we have been searching for new changes and arduous exploration. The “Jinyinfeng” water-free dyeing machine has created a new world of printing and dyeing technology, filling the gap between international and domestic, and has realized the development from mass production to domestic production. In the future, “Jinyinfeng” will surely bring profound changes to the global printing and dyeing industry with its cutting-edge technology, adding a colorful page to “Made in China 2025”!
