Technological Innovation Will Promote Great Changes In China'S Textile And Dyeing Industry.

2017 is the great year of environmental protection in China.

In particular, the remediation of polluters and dyeing and printing industry has never stopped: Shaoxing Keqiao "every Monday" environmental protection law enforcement, Fujian Changle crack down on "black dye" joint law enforcement, Jiangsu "263" environmental protection battle.

As a typical representative of traditional industries, the textile printing and dyeing industry is facing not only environmental high pressure, but also the rising cost of enterprises. Due to the backward equipment technology and serious environmental pollution, it has reached the critical point of the industrial revolution.

How to save cost and environmental protection has become a difficult task for many printing and dyeing enterprises.

The picture shows Dyan's textile printing and dyeing production line using eco photoelectric intelligent printing and dyeing system technology.

At the beginning of this year, the first eco photoelectric intelligent dyeing and printing plant in China was formally put into operation.

The factory, called Suzhou Di Li an environmental protection technology Co., Ltd. is located in the Wujiang scenic area of Suzhou, Taihu.

As we all know, the Taihu river basin is a key ecological protection area in China. The state strictly prevents Taihu from polluting any enterprise within 10 kilometers.

What kind of environmental protection technology can allow high polluting printing and dyeing enterprises to put into production in scenic spots?

The textile printing and dyeing industry in Wujiang District of Suzhou has a long history. It is a famous textile and dyeing industry gathering area in China. It is one of the 4 famous textile bases in China. There are more than 5000 textile enterprises in Shengze Town, with an annual output of tens of millions of meters of cloth.

Once upon a time, the textile and dyeing industry also created serious environmental pollution while creating a lot of wealth.

Unfortunately, the traditional cylinder dyeing technology, which has been followed for more than two thousand years, uses liquid water to finish the dyeing process. It is commonly known as "washing the big pool". Therefore, textile printing and dyeing has become a highly polluting industry.

It is estimated that a small printing and dyeing plant will produce at least 2000 tons of waste water and 10 tons of waste sludge in 1 days.

However, as a key ecological protection area, in order to restore the water of a lake in Taihu, local government departments at various levels have frequent heavy punches to control Taihu's water pollution. In recent years, a batch of small and medium-sized printing and dyeing enterprises have been forced to shut down.

Moreover, according to National Statistics Department, China is a major producer of textile products in the world. Its revenue in 2016 was about 4 trillion yuan, of which textile printing and dyeing industry amounted to 380 billion yuan, accounting for more than 80% of the world's output.

According to statistics, the total amount of dyed fabric in China is more than 53 billion 300 million meters per year, and 3 to 5 tons of waste water will be generated for every 100 meters of cloth.

The wastewater discharged in 1 years is about 21 million tons, equivalent to 150 water storage capacity in West Lake, Hangzhou.

For a long time, the relevant government departments and enterprises have spent a lot of money on the pollution problem of the printing and dyeing industry, but have not been fundamentally solved at the source.

"Being put into operation on the beautiful bank of Taihu is enough to prove the reliability of the technology of eco photoelectric intelligent printing and dyeing system."

In the office of Di Lian, a company official pointed to Taihu not far away told the Economic Daily reporters, here is less than 5 kilometers from Taihu, is within the scope of strict control of the state.

The reason why the company can go into production smoothly is that Diglia does not have boilers, and has truly achieved zero emissions of waste water and waste gas.

It can be said that the technology of eco photoelectric intelligent printing and dyeing system will make Shengze's printing and dyeing enterprises see new vitality.

According to Qiu Jizhong, chairman of Suzhou Dili environmental protection technology company and the technology inventor of eco photoelectric intelligent printing and dyeing system, since 2010, the company has carried out scientific and technological tackling against the characteristics of traditional cylinder dyeing process which is characterized by high pollution, high energy consumption and low efficiency. After 8 years of innovation and application, the DLN Green Eco photoelectric intelligent printing and dyeing system developed by ourselves has finally changed the traditional process of dyeing and distributing cylinders in 2800.

Qiu Jizhong said with great emotion, "this is the beginning of the" environmental revolution "of" zero emissions "in the textile printing and dyeing industry.

I believe that printing and dyeing wastewater, which accounts for about 10% of the total industrial wastewater discharge, is expected to be effectively eradicated. "

Qiu Jizhong introduced that the core of eco photoelectric intelligent printing and dyeing system technology is to use a new type of dye and photoelectric technology, adopt a momentary coloring mode, completely subvert the traditional cylinder dyeing process, do not need water printing and dyeing and cleaning, do not need traditional waste water treatment, and do not need boiler hot (steaming) gas supply.

Qiu Jizhong said that the technology of eco photoelectric intelligent printing and dyeing system has obtained a number of national patent certificates.

The company has 3 eco intelligent printing and dyeing production lines.

When the reporter walked into the workshop, he saw a large volume of it.

After passing through the drum and dye trough, the product line is evenly coloured on a production line. Then it is sent to the rolling mill and extruded by special technological process. Then it enters into the high temperature oven which can be controlled intelligently and temperature up to 245 degrees.

After a few minutes, the red cloth with even bright colourful colors is continuously coming out from the other end of the oven.

There are no common sewage crossflow, steam and odor in traditional printing and dyeing factories.

The 1 production line only needs 4 employees to control and manage, and the site is in good order.

Qiu Jizhong said that the various millions of meters of finished fabrics printed and printed by Delian company have been tested many times by authoritative bodies (SGS/BV/ITTC, etc.). The quality indexes such as color fastness, color difference and safety of chemical auxiliaries of printing and dyeing fabrics have all reached the national and European standards.

Due to its excellent ecological environment, the company has become a model of local ecological environmental protection. The emergence of eco optoelectronic printing and dyeing system has achieved zero discharge of printing and dyeing wastewater, bringing new vitality to the local printing and dyeing industry.

According to Qiu Jizhong, such an ecological intelligent printing and dyeing line will not only achieve "zero discharge" of waste water, but also reduce the production cost by 25%, save 50% artificially and reduce the floor area by 80%.

In traditional printing and dyeing enterprises, 8 dyeing VATS produce about 8000 meters per day, and the daily output of this new process can be increased by 8 times to 72 thousand meters.

And each production line is equivalent to 8 dyeing vats, 1 sets of machines and thousands of tons of waste water treatment equipment.

Take the Wujiang District of Suzhou, where the company is located, for example, according to this standard, if the technology of eco optoelectronic intelligent printing and dyeing system is widely applied in the local textile printing and dyeing industry, the direct economic benefits created annually will exceed 100 billion yuan, and all kinds of ecological benefits indirectly will be immeasurable.

In today's world, the general trend of technological innovation is rapidly impacting and changing our social and economic life.

As an important measure to promote the strategy of manufacturing power in China, intelligent manufacturing is to build a strong textile country and realize science and technology.

The important path of green textile new positioning.

Qiu Jizhong said that Darien will continue to use technology innovation drive, strengthen standard support, realize the digitalization, automation and intellectualization of textile dyeing process, help China's textile industry intelligent manufacturing, take intelligent workshop as a breakthrough, form digital driven factory, promote integration, and foster intelligent manufacturing ecology, so as to eliminate pollution of printing and dyeing wastewater and make progress towards "green water, green hills, and Jinshan Yinshan".

According to Qiu Jizhong, they are currently working together in Suzhou and Henan and Xinyang to build a new large-scale ecological printing and dyeing factory, in order to further enhance the environmental intelligence manufacturing and pform the traditional printing and dyeing industry, and accelerate the progress of demonstration construction.
