Wujin Supports The Technological Innovation Of Enterprises And Brings Them Back To Life.

Spin

It has always been recognized as a heavy polluting industry.

Against the backdrop of a good fight against pollution control, Changzhou, Jiangsu, took the "263" environmental remediation special action as the starting point to stop and consolidate several enterprises.

In the throes of pain, textile and dyeing enterprises continue to seek a way out.

Changzhou Yun Da printing and dyeing Co., Ltd. (hereinafter referred to as "Tatsu dyeing and printing") developed anhydrous printing and dyeing technology, pforming the original pollution industry into a low energy consumption and no water industry, and embarked on the road of green development.

Big polluters must pform

Wujin supports enterprises to take the road of pformation and upgrading of technological innovation

Gathering in the printing and dyeing industry

,

In the two provinces, the output of products accounts for almost half of the total output of the country.

Data show that in January 2017 ~11 months, Jiangsu chemical fiber production was 13 million 538 thousand and 600 tons.

There are many textile and dyeing enterprises in Wujin, Changzhou. With extensive development mode and heavy industrial structure, many problems have been brought to industrial planning, industry management and pollution control, and the ecological environment has become an obvious short board.

Although Wujin has shut down a number of enterprises in the previous environmental renovation, how to pform and upgrade printing and dyeing enterprises has been a problem that the government and enterprises have been thinking about in the context of stringent environmental requirements.

This reporter has learned that Yun Da dyeing and printing is located in Hutang town of Wujin, mainly engaged in weaving, denim finishing and dyeing of white cloth. It has 28 dyed cylinders and produces 2000 tons of fabric annually, producing 200 thousand tons of printing and dyeing wastewater.

The traditional printing and dyeing process must be treated by high temperature and high pressure, resulting in a large amount of printing and dyeing wastewater and exhaust gas. Such a printing and dyeing enterprise was once listed as a closing list.

On the basis of widely soliciting opinions and suggestions from enterprises, Wujin District first introduced the two documents of "shutting down enterprise support policies" and "safety shut-off guidelines" in May 12, 2017, clearly supporting enterprises to take the road of technological innovation pformation and upgrading.

As a result, the printing and dyeing industry has embarked on the upgrading road through ecology.

No need for a drop of water for printing without water.

Dyeing and finishing auxiliaries were developed by Yun Da printing and dyeing, and clean dyeing without pollution and zero discharge was realized.

As early as the "263" special action started, with the continuous improvement of environmental protection requirements and continuous high pressure, Wujin's printing and dyeing enterprises have realized the environmental bottlenecks they encountered and began to seek the outlet actively.

Since its beginning in 2016, it has been working with experts from the China Aerospace Research Institute, East China University of Science and Technology and Jiangsu University to develop polymer dyeing auxiliaries.

After tens of thousands of experiments, Tatsu dyeing and printing has solved the problem of dark penetration, and successfully achieved the breakthrough of non water printing and dyeing technology on chemical fiber fabrics.

The traditional printing and dyeing process must pass through high temperature and high pressure to produce a large amount of printing and dyeing wastewater and waste gas. Without water printing and dyeing, the whole dyeing process does not require high temperature and high pressure, nor does it need a drop of water.

According to the national garment quality supervision and inspection center, all the indicators of dyeing cloth using this technology conform to the national standard.

So far,

Eliminate 28 dye vats in one fell swoop and pform from a traditional printing and dyeing enterprise to an environmental protection enterprise that promotes anhydrous printing and dyeing technology.

"I have calculated an account. The traditional process of printing and dyeing one ton of cloth requires about 100 tons of water. The printing and dyeing without water can save 70 tons of water per ton of weaving, plus steam, electricity and labor costs. The cost per ton is more than 2000 yuan.

For an enterprise, saving electricity and saving coal may add up to millions of dollars, but if it is in the whole country

The promotion of enterprises will contribute greatly to reducing energy consumption and reducing pollutant emissions. "

Zhang Anda, chairman of Yun Da dyeing and printing, said, "after that, we should continue to study and extend the technology from the present polyester to cotton, nylon and so on, so that more printing and dyeing enterprises can use anhydrous technology."

Many companies hope to try.

Hutang printing and dyeing industry actively integrates resources, pays attention to environmental protection and green development, and forms resources sharing.

The dyeing and printing technology of Tatsu printing and dyeing has been favored by many enterprises.

"I have been looking for technological upgrading and upgrading space."

Hutang local enterprise and broadside group leader said, "I heard that there are

Technology, pollution-free, energy saving and environmental protection, our enterprises hope to have a try. "

The head of Guangdong song Xingtai weaving company was also delighted to see the printing and dyeing after the on-the-spot investigation. "Under the situation of ecological environment protection and green development, enterprises are also faced with the problem of the reduction of pollutant emission index and the restriction of production capacity. The anhydrous printing and dyeing can effectively solve the problems faced by printing and dyeing enterprises, and we believe that this technology is worth promoting."

It is understood that at present, Guangdong printing and dyeing enterprise, song Xingtai weaving has reached a cooperation agreement with the Tatsu dyeing and printing company, and the trial production has been successful.

The Broadway group has also carried out docking with Yun Da printing and dyeing.

Chen Zhihua, President of China printing and dyeing industry association, said that the promotion of anhydrous printing and dyeing technology will be applied to the whole province and even the whole country.

The industrial structure and resource conservation and utilization have great value.

In February 4, 2018, the Hutang chamber of Commerce reached the "printing and dyeing ecological co construction million light fund".

Zhang Anda said he donated millions of yuan to set up a fund so that more printing and dyeing enterprises can see hope and get out of the predicament.

This is only a microcosm of cooperation between Hutang textile and dyeing enterprises.

At the local level, textile printing and dyeing enterprises are actively seeking a way out for the whole industry. In addition to actively integrating resources and achieving resource sharing and complementary advantages under the leadership of the Hutang chamber of Commerce, enterprises are paying more attention to environmental protection and paying attention to their green development.

In the town of Hutang, there are such a group of enterprises, hoping to rely on excellent facilities and good environment to become the leading sheep of the industry and the benchmark of green development.

"If enterprises want to develop and survive, they will not rely on themselves but pform and upgrade."

Local entrepreneurs said.
